77 Super Glide Won't Run When Hot
I got a 77 Super Glide, about 500 miles on a rebuilt motor. It's a Harley shovelhead bored out 30 over with a s&s super e carb. It starts cold first try every time. Runs awesome, sputters a little bit in 3rd going 30, but I'm sure thats normal at that rpm. However, if I go for a ride then let it sit for more than, like 10 mins, it won't run for anything. It spits and coughs and dies. I have to keep starting it, and after about the 4th or 5th time of running and dying, it finally comes around, and its good to go again. Help??

Flooded! I think what's happening is you're flooding when hot. Float level too high or junk in the inlet valve hanging the float. Info you provided sez starts right up when cold---that says rich mixture--then take for a ride, get hot still runs good?? then let sit for short time.. gas floods into motor- won't start -- let sit longer time, will start, run ok, gas has evaporated from hot motor.
Try this... cold start, run bike along till warmed up, reach down and shut off petcock, keep riding till you run out of gas. Coast to side, turn on gas and start up quickly. Should be OK. Sometimes this will clearthe junk from the inlet valve (Valve opens all the way when you run out, reopening petcock flushes junk into float bowl) By the way, How's your kickstand? a big tilt on the bike will cause the gas to flood down the manifold and flood you out. You want to fix this cause a new motor won't seat the rings right if the gas keeps sloshing in there. Go to S&S site and print out tuning instructions for the E carb. Follow instructions. Ride safe.
