Got the truck up and running on the road...new problem. I traveled about 4 miles from home, when it was warmed up and it died at a stop sign. Started up with a few cranks. I found had to keep the RPMs above maybe 2000 to keep it running. Anything below that and it would die. When it had died, and I started it back up, then it would idle until I brought the RPMs back up then it would die again under 2000 RPMs. When cold, it will now run fine again. Being a COE, it does have the updraft carb, and I believe it has a governor on it (small aluminum little divice between the intake and the carburator)? Anybody experience something simular to this?
