I hate carbs!, I have to convert if F.I. for my big 4! Options

Webers are brand new and seem to fall out of tune(especially part throttle) very quickly. I know nothing about carbs so this is very frustrating. I feel much more comfortable with electronic control and tuning. I am looking to talk to the guys who have an aftermarket system on a flat four and have had good luck with it. Can this be done for $2500? Also in the mean time where do I look to learn a bit about these damn Webers and some rookie tuning instructions.

Signed, Carb ignorant.

That explains alot... One problem with the huge bores is unstable running...
The carbs are showing you an engine issue and illustrating it with the adjustment issues..

mammoth expansion during the heating cycles causes the issues that you are experiencing now. The carbs may be slightly out but you'd be suprised at what they would do on another engine.

There is no port work done to the heads?? WOW, holy port velocity!

I'd like to see the exhaust system, as that is also a huge contributing factor to carbs that are unable to be adjusted on a TIV engine. Exhaust is key, and most of the "custom" systems that muffler shops and etc whang together kill engines.

in this case doubt the carbs last, they can only do what the engine will let them do.
