Spits when Hot !

[pastortom1]

I have a mildly built 360, with what appears to be an older Edelbrock "Torker" or something...Edelbrock is in the old script....looks like a mild high rise.....Anyway, the Holley is setting directly on top with nothing but a gasket..........

Shouldn't this have a spacer to help insulate the bowls from heat transfer?

The motor runs crappy when it's hot......step on it and it spits or pops at me like a vapor lock or something..........

I know I need a good insulated fuel line, but I don't think this carb is right without a spacer......gas too hot probably?....You can smell the fuel too when it's hot, and there are no leaks.

Can somebody help out here? :read2:

Tom,

I think an open phenolic spacer would help your problem.

How thick would you say..............an inch or less? :read2:

Kinda depends on your throttle cable set-up and application. If you want a bit more top end power and the throttle cable is long enough, I'd go with the 1". If your only looking for carb insulation a 1/2" spacer should do the trick.

Don't use aluminum as it conducts heat like crazy. Phenolic spacers are pretty tough and seal well. Moroso even makes one of wood but I have no experience with it.
