carburator question

[dick2256]

needle valve sticking on my corvair
am using ethanol what kind of additive should I use
to help prevent this?

[John Fenner]

Ethanol as in E10 mix in your pump gas I assume, or are you running E85?
Is it a mono jet?

Hi John I don't think it is E85 I think it is around 80
It is the cheapest gas I can buy
the carburetor is a 2 jet Rochester that came out of a 1963 Chevy I think.
sets on top of a cross over tube that goes to each side to a intake carburetor port

You might need to change needle and seat to an alcohol resistant viton type, doubtful there is a racing steel needle type for dualjet.
