I just read the following on another forum talking about someone elses carburator:
"The main jet is in the center where the middle bowl/mixture screw goes into. Up inside there is the main jet, it looks like a flat headed bolt with a hole in the middle and a groove for a flat head screw driver. Unless you are buying the new jet, do not remove it. A couple other guys referenced a bread tie wire or the likes, they were talking about using a small wire to go up inside there and clean it out. If it sat with gas in it for any length of time, it will probably be plugged with old gas build up which then causes rpm surge while running as it's starving for gas."
It makes me wonder if this may have been removed from my carb but not replaced. I know that there is a fuel shot off, a sediment bowl, then the carb and everything before the carb was plugged solid.
Alan, I am not sure just where the settings are at this point, as it is finally running really well, except it seems like it needs a little more gas and a little less air. It even starts pretty easy. I have started it with 2 or 3 pulls at a cold start. If I get time today or tomorrow, maybe I'll try to make a short video. Anyway, if I try resetting the adjustments, I will check to see just where they are at this time and maybe start keeping a record to help myself.
