Carb for 408
I'm using this one with a 750 DP after having to modify it by cutting a slot for the secondary pump arm, as well as cutting out the middle making it open. Helps, but the primary pump does percolate some after shut down. Never had any heat issues with the Street Demon with polymer bowl, running or parked. That's in my van with the engine under a doghouse which traps heat after shut down, if I don't raise the cover to let it vent.
