Alky carb won't idle

[stryker69]

Will run great before heat race then won't run unless setting idle at 2 grand rpm. Fuel seems to be hot in the fuel cell.

How much fuel pressure at idle? What type of bypass are you using? etc...

[stryker69]

With idle set at 1300 it's at 4 psi and 6 when I have to idle it up to 2000, have a kse belt drive pump with a blp bypass regulator

Check your float levels and air bleed screws. What type of carb is it?

[stryker69]

It a blp 4150.... Should I raise the floats up?

Check for an air leak in the fuel line somewhere(mine was at the fuel log going into carb). I had one did similar and i think it was sucking air once it warmed up, had the wrong size hose on a pushloc fitting

Also check to make sure its not getting to high of a fuel level in the bowls after you get done running and that is when your problem is I have ran into this a lot if it will start coming out of the boosters as it gets too high and if it continues it will come out of the vent tubes sometimes its the floats sticking and most of the time it will be the needles sticking and not closing back off causing the engine to flood hope this helps good luck
