Restarted, but needed chock to stay running...well, idling fast. Throttle is not smooth, but rather touchy/jumpy. Any suggestions on where to start troubleshooting. My thoughts:
1. Fuel pump.
2. Trash in carb idle circuit.
I don't think carb is flooding as chock is required to keep it running. Still starts easily, so probably not ignition. | | | | | Joined: Nov 2002 Posts: 2,766 Carburetion specialist | | Carburetion specialist Joined: Nov 2002 Posts: 2,766 | Trash in the idle circuit is a possibility, however:
Carburetors go bad over years, even decades.
Ignition systems go bad in the blick of an eye, especially the electronic ones.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify.

Sometimes that draws a big slug of liquid gasoline through passages that normally only see vapors or gas/air emulsion. Can't do any damage, and sometimes a small chunk of trash will get flushed away.

In addition to this kind of incite, there is also his mild mannered temperament, always polite discourse, and his caring and comforting demeanor. Let me know if I left anything out.  Carl

You were almost poetic, in using incite instead of insight to describe Jerry's style of posting assistance. Your double entendre was almost poetic. | | | | | Joined: Jan 2013 Posts: 1,084 'Bolter | | 'Bolter Joined: Jan 2013 Posts: 1,084 | That's a sweet fix Jerry.

Jerry, I think they are trying to 'roast' you in absentia.
But to what Mr. Lane stated...+1.
