force 50 1987c wont idle or start well when hot

[daveinmichigan]

Can someone give me a couple ideas what makes my 1987 50 force not idle and tough to start when hot.... when its cold it starts as soon as i crank it.. i rebuilt the motor it has good compression and i have run 4 gallons of gas thru it to try and let it clean itself out but its staying the same. Fires right up when it sits a while and i can force it to run if i crank the starter and give somethrottle right away it just will not idle when its hot it does still do the same overall speed when wide open hot or cold.

thanks dave.

One other thing is i found the idle mixture screw 3 turns out ...does it effect differently from hot to cold at all?

If your Idle mixture screw does not make a difference ether you have a plugged passage in you carb or you have an vacuum leak in the carb/engine some where.
