[QUOTE="CMOS, post: 432146, member: 15462"] Thanks Pappy. Yes, the motor is keeping a good consistent head temperature. I was regularly placing my hand on the top of the head for easily 10 seconds. With regards to your comments about advancing the throttle: When the idle dropped low I would re-prime the fuel line while advancing the throttle just enough to keep her running. After several seconds I could hear the RPM's increase a bit at which time would back off the throttle to IDLE, and observed the smooth idle. After a few minutes the low idle would return. Rinse and repeat... When the idle was operating normally, the mixture screw is set right where it needs to be per the standard adjustment technique (small adjustment, wait...). So other than fuel availability, I'm not sure what would cause the intermittent low idle. I am using Champion plugs. I will pull the fuel pump and look for leaks. And I will try the next test by ONLY using the primer bulb, not advancing the throttle. I'm so close to getting this baby running. CMOS [/QUOTE]
