Carbs, Fat, Protein

Time to take a look at the carbs. I have set the timing, valves, and new points, still running hard. New plugs coming this week, but I thought it would not hurt to take a look at the jets.

I went ahead and broke them down them Sunday night to discover some tank flakes, paste in the atomizer's, idle jet, and mixture screw area. I went ahead and used Gunk and Simple Green to clean and blow out everything I could find. The o-rings, and gaskets need to be replaced, but I figured for now, removing the gunk would at least help me continue my troubleshooting by eliminating any gunk that might effect acceleration or lurching effect during throttle.

I meet a guy from Forney, who suggested looking at the fuel lines, petcocks, since the condition seems fuel related. The next time this lurching, and stalling happens, I'm temped to quickly shutoff the fuel petcocks and remove the bowls to see if there is fuel flow issue. The fuel seems to flow fine with the bowls off at rest. The floats look original, but seem to float level.

I have removed the gas cap before thinking it was a vacumn issue, but that does not seem to help.

I will keep trying until it gets better or worse.

The carburetor enrichener parts orientation. The photo on the left side has a dimple on the shaft, hard to see, points to the lever barrel opening. Photo on the right has its shaft marked R, and it is from a 1978 Airhead, RIGHT side.
