Clutch engages early, so you just gently accelerate away. sadly having not driven TWC I cant say for her, but I know REV does not hang about if you go wide open throttle so i would not say Gently accelerate LOL (although I imagine in REV's case anway if you started it in gear with WOT it would just bog down and stall like she does when your idling away and go WOT suddenly, as you say from a getting up and go POV its not that much different if you where idling and then just decide to go WOT) on a side note I was told of a story where a lady was upgrading from a villiers machine to a Model 70 and she jumped in and just twisted the throttle, I guess expecting it to be like the villiers machines, shot off, panicked and crashed into a milk float! apparently he (the Invacar repair/garage) ended up having to strip that Model 70 down and replace the chassis on it, surprised it wasn't written off entirely! 46 minutes ago, quicksilver said: I did wonder what would happen if you were to start one in gear with the throttle wide open as there doesn't seem to be anything to prevent you doing that. I had visions of it careering off at high* speed and wobbling into the nearest hedge but maybe it wouldn't be that spectacular. I have no desire to find out for myself though. however otherwise yeah they will run away from you! its one of the reasons you ALWAYS MAKE SURE YOUR IN NEUTRAL! before starting the engine especially if you have the choke on! (as the choke raises the engine revs above the clutch engagement speed, as such if your in gear it will move on its own, DIY Cruise control FTW ) for those wondering the clutch starts to engage from 1200 RPM and is fully engaged by 1500 RPM Link to comment Share on other sites More sharing options...
Zelandeth Posted August 19, 2019 Share Posted August 19, 2019 Yes... starting the engine in gear results in the thing taking off at an alarming rate of knots unless restrained. I discovered this hanging out of KPL and chasing the car into the garage early in my ownership. An interlock to disable the starter circuit unless the gearbox is in neutral is on the wishlist for future improvements to TPA. Admittedly it's less of an issue now with TPA as the parking brake is effective enough that she won't actually go anywhere...but it was plenty unnerving before that was the case.

dollywobbler Posted August 20, 2019 Author Share Posted August 20, 2019 Yeah, ok. It is quite sharp if unexpected. On the start line of Shelsley Walsh, it definitely didn't feel quick! LightBulbFun 1 Link to comment Share on other sites More sharing options...
dollywobbler Posted August 20, 2019 Author Share Posted August 20, 2019 The only time an Invacar has climbed Shelsley Walsh. Well, certainly the only time chased by a lawnmower, a fake NYPD Police car and a crazy VW-based bubble buggy thing... brownnova, RayMK, LightBulbFun and 1 other 4 Link to comment Share on other sites More sharing options...
LightBulbFun Posted August 20, 2019 Share Posted August 20, 2019 very happy to see videos on TWC once more I enjoyed this one very much! BTW did the hard top crack always go round the side like that?, might be worth keeping an eye on and making sure it does not grow in size Link to comment Share on other sites More sharing options...
dollywobbler Posted August 20, 2019 Author Share Posted August 20, 2019 Which one? There are many. Link to comment Share on other sites More sharing options...
LightBulbFun Posted August 20, 2019 Share Posted August 20, 2019 this one, although your right the crack I normally think of as the crack in your hard top is the one on the lower left it may be I just have never noticed the crack going round the side before (I did try and check some older Photos I have of TWC however none of them are from that side so I cant tell if its grown or my mind is just messing with me) Link to comment Share on other sites More sharing options...
dollywobbler Posted August 20, 2019 Author Share Posted August 20, 2019 Ah, that has been iffy for some time. I've actually gaffer taped up the one behind my left shoulder (on the inside anyway). I do need to consider some bodywork improvements at some point, but then have the challenge of not wanting her to look restored.

Zelandeth Posted August 21, 2019 Share Posted August 21, 2019 Get some Fibral, P40 (or similar) and slap it on from the inside. It's a fairly thick paste so easily managed and will stay where it's put. No need to have anything visible from outside, but it will help restore the strength of the area to stop the crack spreading and help keep the weather out. This stuff. Still messy, but it's so much easier than messing around with separate matting and resin and is pretty user friendly. I found (far too recently!) that the best way to get things nice and smooth was actually to just use disposable gloves and smooth it over by hand, especially if you're working inside a tight curve or recess which makes getting tools in difficult. Wish I'd worked that out a few months ago. LightBulbFun, dollywobbler and egg 2 1 Link to comment Share on other sites More sharing options...
plasticvandan Posted August 21, 2019 Share Posted August 21, 2019 the problem you have is you seem to have done it back to front,the fibreglass is meant to go on the inside,then the top filled and smoothed off.this stuff is only meant for little repairs,holes etc.it has no strength in it for anything structural.

AdeMk1 Posted August 21, 2019 Share Posted August 21, 2019 You could do to drill a small hole at the end of that crack, it will stop it spreading any further. Link to comment Share on other sites More sharing options...
Zelandeth Posted August 21, 2019 Share Posted August 21, 2019 For small cracks and holes it's more than adequate. While I've not done actual industrial testing, I've abused some of the repairs I've done with it and ascertained that it's more than strong enough so long as it's well keyed to the surface. Well squidged into a hole or crack in a panel it's plenty strong. Probably stronger than the rather low rent fibreglass these bodies are made of to start with!

MorrisItalSLX Posted August 21, 2019 Share Posted August 21, 2019 The thought did cross my mind that you could only patch the cracks on the “hidden” side to reinforce them and prevent them growing whilst preserving the patina and completely negating the need to bugger about with filler, sanding, paint and all that other malarkey. I’m also pleased for you that the spat spark plug was a relatively easy fix. They can be proper pains, hence why the spark plug in my lawn mower is currently held in with Araldite and string.

LightBulbFun Posted September 12, 2019 Share Posted September 12, 2019 happy to see another TWC focused video I enjoyed it very much (and the NMR one too! ) I also enjoyed the bit where @dollywobbler was explaining what TWC was etc and I like to think you where thinking to yourself "ok what did LBF say again in that ramble of his 2 weeks ago? I better get it right or he will complain again!" very happy to see she is happily cruising at 55-60Mph, did you get a chance to look at the distance of the pulleys? according to the workshop manual it should be exactly 10.25 inches between the centre of the 2 pulley shafts as seen in the manual and in this letter to all approved repairers to RTFM! (it seems people where trying to adjust the belt tension by eye and not actually reading the workshop manual. its said at the start of the Model 70 there were quite a few transmission issues, a lot apparently down to the fact that most repairs had no experience dealing with a CVT system) BlankFrank, Six-cylinder and Eddie Honda 3 Link to comment Share on other sites More sharing options...

Zelandeth Posted September 12, 2019 Share Posted September 12, 2019 Nice to see her out and about again. Just watching the video now as it's the first real chance I've had. Definitely worth giving setting the belt by distance as a test. The reduction in "thrashy belt" noises at speed was quite noticeable on TPA when I did that. Still quite gutted I couldn't make it down...I was still half toying with taking TPA down, though once the wheel stud went ping that was the end of that. She's definitely going to be there next year if I have my way... LightBulbFun 1 Link to comment Share on other sites More sharing options...
LightBulbFun Posted September 25, 2019 Share Posted September 25, 2019 DHSS Workshop Manual For The Model 70 Three Wheeler(OCR).pdf for @dollywobbler as mentioned at the FoD, here's the workshop manual scanned in high quality colour by @Zelandeth and then OCRed by @1970mgb (that means you can search it! although as the DVLA database clearly demonstrates, OCR is not perfect) (I was holding off making this public as I know Zel said he wanted to to tweak a couple things and scan the workshop manual again, but given how busy he is currently I think its best I share the copy I have and then I can update it when Zel produces his final example ) for what its worth the bad quality Manual we had before hand Does mention the 10.25 inch Pulley distance thing so I will leave you with a picture of this Tippen delta davocano and adw1977 2 Link to comment Share on other sites More sharing options...
LightBulbFun Posted September 26, 2019 Share Posted September 26, 2019 BTW @dollywobbler did you do this step when you changed the diff oil on TWC? I dont see you mention it in the video so I just want to double check as it seems like it would be an easy step to miss! (also note the very helpful* guide on how to tension the Triplex chain! *sigh* LOL ) Link to comment Share on other sites More sharing options...

(I did notice you had a couple printed sheets of the manual in the video, did Elmsleigh Invacar print those off for you? I would love to have a rummage around the place and see what they have! I do wonder if a workshop manual for the Invacar Mk12 and such like also existed) (I do wonder what the procedure is for tensioning the chain would be, maybe a Saab owner would know!) for future reference when out and about id recommend saving the manual to your phone or such Link to comment Share on other sites More sharing options...
Jikovron Posted September 26, 2019 Share Posted September 26, 2019 It's probably only applicable to transmissions that are fully dry of oil when new or rebuilt rather than an oil change situation . Link to comment Share on other sites More sharing options...

dollywobbler Posted September 27, 2019 Author Share Posted September 27, 2019 Meh. It sounds like it's going to die at some point anyway. Not much point worrying now. In other news, I got confused between cars, and the Invacar does NOT use the cathedral-style connector for its indicator stalk. That must have been the Fox. I ordered a selection of Lucas stalks as a job lot, and none of them fit. Yay! So, I've tied the stalk to the handlebar for now, so there's no main beam. That'll do. With New Zealand looming, I can't justify any further expenditure on the fleet at the moment. Taking the Invacar on a road run on Sunday. Weather forecast is entirely terrible. Maybe I should have refitted the demister... Link to comment Share on other sites More sharing options...
