I've seen several threads on this but nothing that actually has a fix. My speedster is relatively new and came with a completely new engine build with dual carbs. Cold start is always perfect, but after my engine is warm, I have to crank it for probably 10+ seconds or so until the fuel/carbs sort themselves out and the engine starts. Pretty embarrassing when everyone is looking at your cool car and it barely starts.
I've tried the various recommendations on pedal to the floor, crank it until it catches a spark and then feather the gas... Still nothing that gets me a clean start when the engine is warm and it has been this way since it was new. To be fair, its never not started for me, but always takes alot of cranking when warm.
Here a picture of my setup with the fuel regulator while the engine is idling. Let me know if anyone has ideas on an actual fix I can do. BTW, my engine is a thing of beauty isn't it!!!
