Not married yet and already got solid grounds for divorce she doesn't know I've bought it!

Anyone got any tips/info on care and maintenance for this type of engine?

i'd say you need a rolling road but some old school mechanics can tune these by ear and not be far off the mark .

Twin Webers = lots of noise and lots of petrol, lots of drama .

The car in question looks tidy and has some morsels but it is not a recipe I would recommend for somebody who is not too techy when it comes to turds :o

Anything not running webbers. Perhaps a relatively modern lump like say...a 318iS?

you could just swap the webbers out for the standard carb set up it had on when it left the factory for not alot of outlay :idea:

Do they make a big difference? I had an is before I wonder how it''ll compare to drive. I wouldn't want to swap them out if it strips the performance too much.

Best to set them up using a Gunsons Colortune and Carbalancer, as shown here:



If you can't get it to run right, they may need rejetting to suit the engine.

The Colortune is screwed in place of a spark plug and lets you see the colour of the combustion flame, so you can set the mixture to the correct light blue flame - not strictly necessary (you can just go on the colour of the plug tips), but helpful.

The Carbalancer is a gadget that shows you the amount the carbs are sucking, so you stick it in each barrel and adjust the carbs so they are drawing more or less the same amount of air - this balances them.

Unless the mixture and balance are set properly, the engine will run roughly, be down on power, and probably use more fuel than it should, so it pays to get them set up right.

Welcome back to the e30 fold Paul. That car looked to be a bit of a bargain. I would say find a good mechanic familiar with carb setups. I can recommend a garage down my way that specialise in rally cars and cars of the older variety.

They are actually fairly straightforward carbs once you get used to them. Just a collection of emulsion tubes, jets, etc., that atomise the fuel/air mixture and direct it around the carb ports.

However, setting up a pair of twin Webers isn't for a novice, so best to let someone who knows their onions look at them.

Take it to someone with a rolling road and gas analyser and ask them to set it up properly. That's the only way you'll get them spot on. Get the ignition timing and valve clearances done whilst you're there as they'll play a large part in how it runs.

With a dizzy with a good ignition advance unit on it, and the right jets, 120HP shouldn't be too hard to get out of it, along with a big bag of torque between 3.5 and 4.5k rpm.

Don't listen to the doom mongers, I've had twin webers on 3 cars, never had any reliability problems on any of them. Twin factory downdraughts on a 205xs, never had to touch them in 38k miles of use and twin 40 dcoes on a pinto engined westfield (sub 20 mpg thirst, but thats what happens when you squeeze as much as you can out of one of these lumps) and twin 40's also on a van engined 924 with a home brew manifold, economy wasn't much worse than my other standard one and performance seemed better. This one did need a tune before every MOT, but thats probably more to do with them still being jetted for the Lotus they came off.
