I was able to adjust the carb to get the engine to stay running, had the idle at 1800 rpm as the book suggests to warm up the engine before making the finnal adjustments. After about 5 minutes, ity stalled out. Rpms dropped to nothing. I think it is 1 of 2 posible problems, maybe both together.
The carb got too hot from the manifold,( I haven't purchased a heat shield yet) or due to my terible exhaust(which I plan to replace later this summer, i hope) the engine was pulling in more CO than air. (not enough airflow in the garage) seems like the CO was worse than was in the past. Bieng in the garage it just accumilates.
So, I got some insulation from work which holds up to 500degrees F + to place behind the carb and I am going to place a couple fans in the garage to blow the CO out and see if I can keep the engine running this time.
Oh, and once the engine stalls out, It won't start back up until it cools down.
