Precrossflow gt carb advice

[chinkamon]

Hi all 

 

So finally decided to bolt my proper GT carb on my precrossflow, however I was asked should there b a sandwich plate between the carb an the manifold, when running there's a little " flutter " and we're tryin to get it running smoothly,

I don't believe so - not as std anyway. The sandwich plates were more (an attempt) to stop heat transmission from manifold to carb with water heated manifolds.

That's great thanks very much

It’s a proper thick gasket about 8mm thick.

Normally a black plastic affair with gasket both sides

Thank you guys,

Another thing, I'm running a GT carb on a standard motor, is the mechanical fuel pump man enough?

Only because I see the delivery pressures are different in my book?

1.25-2.5pounds per sq inch for standard

2.75-4.25pounds per sq inch for gt an lotus?

Simple terms yes
