Carb question

[Pro Stock]

If you suspect that a fuel line is to close to a source of heat (header ect.) fix that first, put an insualator between the block and fuel pump and make sure that the fuel line from the pump to the carb is isolated from heat with proper routing and an insualting sleeve over it, also run an insualating gasket under the carb this way you will have addressed all of the heat issues at once. Check your float levels while the engine is running, your Demon carbs floats should be set so that the fuel level is halfway up the sight glass, are you running a regulator ?, if not you should be, set he regulator to about 6 1/2 psi, I would also run a BG regulator with a small guage attached to it so that you will always be able to see what your fuel pressure is if your having a problem. When you said that your fuel pump was to big, were you talking about an electrical pump or mechanical ?, if it is electrical and big enough you can take the mechanical pump out of the system and eliminate that source of heat. As stated above correct timing is critical and incorrect timing can show up as a carb problem,retarded timing will also cause the engine to run hot, unless your running a compression ratio above 10.5:1 and less than 92 octane fuel you should be able to run 36* total timing.
