what can i do to stop or reduce my fuel boiling in the carby???
this is a huge problem for me in the car and i dont want to put a scoop on the car but i was thinking that a cold air intake which surrounds the carb and the air filter with two tubes leading to the front of the car coming from the left and right will suck cool air into the carb and in return cool it and give me more power????

put a bigger spacer on it .. and make sure all the fuel lines are well clear of anything hot!!

Or you could try fuel injection and throw the carby.

Depending on the type of carby, you can run a fuel return line from the fuel bowl back to the tank - this ensures the bowl always has cool fuel entering - the fuel doesn't have time to heat up. It is common on race engines and the parts you need are readily available through speed shops.

already used a 1/2 inch insulator plate and it made a difference but it only took longer for the motor to play up, i was however told that there is some sort of a plate that is used on earlier model holdens that basically works like a insulator plate but also sticks out further to protect heat from going directly off the engine and onto the bowls. how do i change the bowls on the carby around so i dont have the fuel lines running over the engine along the fire wall and if u could explain in detail cuz i aint too good with cars?

What type of manifold are you running?
I changed the iron manifold on an XA GT for an alloy one
and started having vapor lock problems.
When I swapped manifolds I didn't replace the factory
tin oil splash shield underneath it . [keeps hot oil off the
bottom of the manifold]
When I put it back in the vapor lock problem stopped.
Hope this helps..

What problems are you getting to indicate that the fuel is boiling

There is a gasket available that is kind of thick stiff cardboard stuff[great description] that extends out under the bowls..If your fuel line or regulator if you have one runs along the firewall you really need to move it out to the front of the engine bay to help keep it a bit cooler..You can also use some foam refrigeration tube available from hardware shops,to run the fuel lines in...

The gasket is made by Redline and available from all good speed shops also the spacer you need to run should be a phenolic block sold by MR GASKET and has air pockets underneath to stop carb heat ..is avail for spread and square bore carbs..
