Corvair Forum

Hard to diagnose without driving. It could be carburetor or ignition issues. Is it a hard jerking when trying to accelerate? Hard acceleration or light acceleration? I have seen a bad coil cause a very rough engine during acceleration but run smooth at part throttle. I have seen coils that only caus...

This may not be a yes or no question. There are several ways to synchronize carburetors depending on who you ask and how picky you want to be. As far as disconnecting the balance tube and plugging the lines this can be considered optional. I have tried it both ways and found that disconnecting and p...

Another thing to check is that the battery is putting out positive from the positive terminal. It is possible although rare that the battery could of been charged up backwards reversing the battery output. This can happen if the battery was completely dead and a charger connected backwards. The batt...

A long time ago I had a similar rocker failure at the ball pivot area. During my recent rebuild I thought new rocker arms would be wise until I saw the information from the Covair aircraft conversion group about the Chinese rockers failing prematurely.

Engine temperature on each bank is influenced by rich or lean mixtures. Not only that the carburetor part number be matc...

Idling issues and the 1965 engine you have caught my attention. Have you checked out everything others here have offered here that could cause idling issues? If you have eliminated everything else and are still having an idle issue I would add that the last thing on the list to check is the carburet...

I had experience circle track racing small block Chevy engines years ago and always thought the Corvair was cool. I built a custom Corvair powered motorcycle some time ago after my racing days. I am now in the process of doing a rebuild of the bike (The original build was mostly used parts). Any inp...
