The flywheel sensors had apparently already been tested and checked out but I decided to test them again seeing as they’ve been mentioned to me by a few people. The sensors are meant to knock out 0.5-2 volts when the peg on the flywheel isn’t directly below them and then go up to 5-7volts when the peg passes by. The output voltages on both were just under 9 volts no matter where the peg was positioned. Is it safe to say the sensors are knackered? I hope so. Just going through this thread and noticed this but not seen anyone else mention it. You've connected up the meter incorrectly. That black wire in the meter should be connected to the terminal marked COM. LightBulbFun 1 Link to comment Share on other sites More sharing options...

SiC Posted October 16, 2021 Share Posted October 16, 2021 Have you tried putting spark testers between the plug and lead? Should flash away while cranking and show quickly if you've got spark. With spark then it's a timing light job to see if they're roughly at the right time. I know very little about these systems, so others may correct, but usually disconnecting a vac line (and plugging it engine side) on an ignition system (both electronic and mechanical dizzy) will cause the system to run effectively static timing only. Simplifies the timing measurements. Link to comment Share on other sites More sharing options...

Lankytim Posted November 4, 2021 Author Share Posted November 4, 2021 I’ve got a few days off work so after finally getting my arse into gear I set about fitting this adaptor gizmo. Stripping the front of the visa away was easy enough although large quantities of organic debris had to be cleared away with a brush and vacuum. A couple of small localised areas require some more welding but I’m pretty pleased I didn’t find any huge gaping holes. The bottom of the front fan cover has been rotted away by the sitting piles of debris but as it’s a removable panel and seemingly only there to direct air I’m not too bothered. I might just trim the corrosion away to smarten it up. Fitting the adaptor was a doddle, I was expecting to drill and tap the block casting to accept the electronic ignition module but I was happy to find that the holes were already present and threaded. After bolting on the backplate with its oil seal the adaptor itself simply slides into the end of the cam and clamps itself in when the centre nut is tightened up. It’s all ready for the electronic ignition module which I’m yet to purchase. I’ll also need to get a 2CV coil and fan as the Visa pulley will now foul the protruding electronic ignition when it’s finally fitted. Buried under the engine was this mystery animal foot, I’m thinking rabbit, does anyone have any ideas? dollywobbler, JMotor, LightBulbFun and 6 others 9 Link to comment Share on other sites More sharing options...

Lankytim Posted November 4, 2021 Author Share Posted November 4, 2021 There's signs of mice living inside the fan shrouding but I can't imagine mice dragging a rabbits foot inside there. Maybe the Visa hit a rabbit at some point in it's distant past and it's foot was amputated by the spinning fan? The plastic mesh over the lower air intake had certainly been dislodged by something. Hopefully I can give the foot a proper Christian burial and "The curse of the rabbits foot" will finally be broken and this Visa will see the road once again! djim, grizgut, Bamboocarman and 5 others 8 Link to comment Share on other sites More sharing options...
Lankytim Posted November 6, 2021 Author Share Posted November 6, 2021 I’ve removed the redundant ignition system (it was kinda redundant anyway), hopefully I’ll be able to sell the working components to another distressed 652cc Visa owner once they’ve been tested. The vacuum advance part seems to be leaking so I’m guessing is dud. It should still run with this part defective but won’t be able to switch to the advanced ignition curve.

I can get an approximate static timing by poking my finger though the upper sensor hole and ensuring the metal peg on the flywheel is directly below. I’m not sure if that will be accurate enough though. Link to comment Share on other sites More sharing options...

Is it possible to set it roughly by the finger method, get it running and then tweak by ear (like turning a dizzy with points) or is the layout such that you cannot do this with the engine running?

MrSteve Posted November 8, 2021 Share Posted November 8, 2021 If you can read french here's the instructions for finding TDC for the adapter I got for my Visa yonks ago (not a Burton one like yours). Looks a bit of a faff hence not done it yet...

grogee Posted November 8, 2021 Share Posted November 8, 2021 Oh man, I SO want this thing to fire up. I would have thought finger/notch method of TDC is good enough to get it running. Then you could use strobe to check timing? Not that I have a strobe. Not even seen one for a long time. Lankytim and tooSavvy 1 1 Link to comment Share on other sites More sharing options...

Lankytim Posted November 8, 2021 Author Share Posted November 8, 2021 I’ve re-read the Burton instructions for finding TDC and I think I’ve got it correct. It doesn’t mention locking the flywheel via a hole in the crank case like the 2CV so maybe the Visa doesn’t have that hole. I’m still waiting for a black 2CV style coil to arrive, I’ve got a pair of brown Visa coils which were pretty hard to get hold of and I’ll be sticking on eBay. As soon as the 2cv coil turns up I’ll have a go at firing the thing up. Once the engine is running the timing can be altered by turning the 123 unit, in a similar way to a conventional distributor. Fine tuning needs to be done with a strobe gun, I’ll have to actually create timing marks using tippex or similar. Talking of the 123 unit, the green light is meant to illuminate as one of the magnets passes under the sensor, however this appears to be reversed with the green light only going off when the magnets pass by.

MrSteve Posted November 8, 2021 Share Posted November 8, 2021 Yes, the 652cc crankcases and flywheels don't have the holes for locking at TDC unlike those on A-series Citroens. Will you be getting the special carb base block with the vacuum feed to get vacuum advance working too, or is the plan just to get the Visa running reliably for now?
