one warm, one alot warmer, intake manifords Options

[karmanbuilt]

After installing dual 40's on a '76 2.0, and running the tall manifords. They were set up by Jake, and started up the first time....Semper Fi! Anyway, after a valve adjustment, tweaking the timing, and fine tuning the carbs, took the car out for a fifthteen mile run. Still need to tweak the carbs, but noticed the bank of 1 & 2 were just barely warm. Bank 3 & 4 were almost hot! Searched the oldies posts back to 2003, and found a thread on gaskets. I had installed my manifolds with the gaskets that Jake had sent with the set, but had to remove the manifolds to plug the holes on each side. Reinstalled the manifolds with the FI gaskets. My question...sorry this is so long....was I suppose to add paper gaskets w/the FI ones??

Okay. There are gaskets sold with phenolic plastic between two paper backings. They are about 1/4 inch thick. This is what I like to use, as is stops heat from the head from wicking up the intake manifold and boiling the gas in the carb bowl. Cooler fuel is better then warmer fuel, right?

as to the heat stuff, your 1/2 bank isn't working as expected. Could be for a whole host of reasons. If you just installed the carbs, they are likely not at all balanced or synced, which is important.

You also could have dirty jets, fouled spark plugs, or some other reason causing the bank of carbs not to work or to work far less then the other one.

You could also have leaks, letting unmetered air in, causing one bank to go really lean.

Your carbs might need rebuilding. Are they old? Have they not been run for over 1 year? If they have not been used, the rubber may have dry-rotted and is now leaky. This is just one of those things that carbs do.

Do you have a unisyn or a syncrometer? Looks like this: (IMG:http://www.914world.com/bbs2/uploads_offsite/www.duckyimports.com-1435-1276637651.1.jpg)
If you don't, get one. You will never get the carbs set right without it.
