3. I'm really crap with cars and can turn even the simplest job into a nightmare. 

You're learning, so don't be too hard on yourself.

I'm having the same problem with a main dealer.

I'm 38, have been driving 20 years and have owned 104 cars. I should be an expert by now. ?

Carburettors are black bastard magic. I bought my 190 as a carb thinking I was beating the system. Whilst KE-Jet is a bit niche nowadays, when working it tends to stay working. 

Carbs? Like a French workforce.

I'm older than you and beyond topping up the dashpot have never touched a carb. Most people don't even lift a bonnet, so keep learning and stay positive. It's one of the better threads.

[DoctorRetro]

It's all back together, but with a makeshift gasket made of card, like my dad used to do. ?

Seemingly running a bit better. Have set the mixture so it's not too rich and turned the idle down a bit. 

Can't really judge until I get a new gasket on there... 

 

[mrbenn]

That sounds a heck of a lot better!

Like your work.

Does it? I'm at that point where I don't know anymore.

Sounds to rev much more cleanly and return to a stronger idle than before, to my ears anyway.

[LightBulbFun]

Ditto, im no expert by far, but it sounds like what id expect that sort of engine to sound like

where as before it sounded rather unhappy!

Keep up the good work!

[DoctorRetro]

Still need to cure the slight misfire, will order correct rotor arm tomorrow as it is payday. 

Also need to find out why it bogs down, either second choke isn't opening or perhaps vacuum advance isn't right. 

And now the auto choke is kaput, might have to convert to manual

[Parky]

Vacuum advance is easy.  Turn the dizzy a few degrees, nip it up, and rev again,  if worse, turn it a few degrees the other way.  If no better, put it back where it was and make some tea.  Treat yourself to a Jaffa cake too.

[tooSavvy]

I am considering a manual choke for mine... I have bought a 6O" bowden.

Also the whole set-up [working very well *atm] is complicated, with multiple vac controlled funtions (3 vac hoses on the Dizzy advance can) and 'auto power/enrichment' with vac control.... I see a veritable nest of hoses running around your carb too.

If you watch the 'weber upgrade' the VERY FIRST thing is dumping the LOT.... You need a single <unported>Vac hose to the Distributor + Petrol!!

I'm deffo going to disconnect the lot/blank off all holes & go Manual Choke. My main *bug, in the general running, is a tendency to just fluff- fluff-chufff... Die! without any warning at lights - starts straight up but I'm sure the AutoChoke is the root of it

Doing real well with this, m8

[DoctorRetro]

I've found a relatively cheap weber..... 

I don't think I can cope with all this vacuum crap. 

[purplebargeken]

AS Fixing Crew - lets all descend and have a mass fettling session. I can clean stuff.

How hard can it be? 

[tooSavvy]

...... Cant really go wrong with that m8

*a spacer/adapter will make the carb bolt pattern on the Maz match the carb.

[DoctorRetro]

Just need to see if I can afford it now.

...... and I think your insurance will not blink, given you have a twin-choke now and you 'inform them you could not source a factory part/NLS' 

[dozeydustman]

She sounds pretty sweet. Been watching this thread and you've got it a millionty-twelve times better than before.

See if you can borrow a timing strobe once you've put the new rotor arm on, helps get the timing bob-on.

[purplebargeken]

Sounds sweet mate, good call re: strobe though. 

Serious about the fixing crew!

[DoctorRetro]

Looking at the difference between the aisan and weber carbs, I'd need a pretty expensive adaptor, which would be about 50 quid. 

I might just soldier on with the current one. 

[DoctorRetro]

Rotor arm finally done. 

Overdue?

 

Started a bit better... 

 

And after a run round the block. Not perfect, bear in mind that the carb gasket is just a piece of card! 

 

 

[TrabbieRonnie]

Top work!

 

[egg]

If you're doing something to an old car that is stopping it getting worse - I call that progress! 

[purplebargeken]

Sounds lovely, a gasket should have that idle sorted.

 

[320touring]

Great work - top stuff for keeping on at it:)

Trouble is finding one. I've got some gasket paper on order and I'm going to have a go at making one.

I've been trying to find a part number for that, just to satisfy my mind, but catcar.info doesn't go back that far and rockauto isn't helping because I don't believe that the US market ever got the carb version of the b-series...

[spartacus]

Is it the carb base gasket? It should be easy enough, if you can get to the manifold then cut a piece of the gasket paper that's about the right size, lay out in position then gently tap around the edges with the end of a screwdriver handle, it'll score the paper exactly where you need it cutting. Alternatively, lay it in position, then press around the edges with your grubby fingers, you'll have a clear witness mark to cut to.

Apologies if I'm teaching you to suck eggs.

Unless a Weber you find is the specific model for your engine it might be more trouble than it's worth. Carb jetting is not as simple as being the same jet sizes for all  1500cc engines, or whatever. You could still end up with a poor running issue, the only benefit being that Weber jets are more*easily* available than Aisan.

I'm not knocking your perseverance though, keep it up please!

A standard 32/36 out the box is about right for 1.3 - 1.6 engines, but that would mean paying 300 quid plus. I've done this plenty of times before, especially on Ladas. 

I'm going to stick to the Aisan for now, and make up a template for the carb gasket, in case I need to make another. Or 6.
