Finally got to go to the Bantam Jeep Festival. Roughly 150 Mi round trip. Stopping for gas found Jeep did not want to remain running had to pull throttle out to higher idle to keep running till on the road. Prior to this only short runs around home. Averaging 14 miles per gallon. This long trip 13 miles per gallon. Stock 46 Willys l134 Carter carb. Followed Scout Pilots timing video and she's been running beautifully. Purchased but have not installed the heat Riser flapper and assembly. Can this be my problem?
This Willys runs at 180 degrees all the time does not overheat. Your guidance in the past has been superb. Everything you have shown me has been spot-on. I want to thank you again for all past and hopefully future help.
Sometimes after running in a new engine the valve clearances close up and you lose your idle. Especially when hot. I'd check your valves and adjust as necessary. You also might double check the tightness of your carburator on the insulator block. They tend to loosen the two base nuts. If it leaks at all, you also lose your idle. I put star washer under the nuts to help. I've also noticed a rough idle due to a worn distributor shaft and bushings. The shaft and rotor should not wobble or move side to side. Oilly
I've had all of those listed affect my running. If you put a new insulator block under your carburator, those two thru rivits where the bolts go through need to be crushed down or it causes a gap that leaks. Some base gasket blocks do not have the rivits. Just depends. Doesn't take much of a leak either. Hope you find it. Oilly
