30hp Chrysler only starts full throttle

[icedogg]

I am not sure, but I think its a 1975, 30 hp. Serial # 1270. Model # 307h2e. Motor will only start and run at full throttle. Spark is good. Compression is good. Carb has been rebuilt. Choke is working fine. Fuel filter and diaphram look good. Head gasket has been replaced. Could it be out of time?? I am running out of ideas.

The main jet in the carb has small holes in it.That is the idle feed.They must be clear.The air screw.Turn in till it bottoms out,then out 1 and 1/2 turn.Start the motor and let it warm.Then turn in the screw until it coughs/bucks,misses.Then out 1/2 turn.J
