correct. a good idle does not rule out a carb problem. - Keep looking at the carb. Sounds like it is running a little lean on idle - a little more fuel is needed during transition through the idle transition ports before it will start drawing fuel through the high speed jets if transition ports are plugged up, that's what will happen - idles fine and stalls on accel.jfon101231 wrote:madmantrapper wrote:Are you saying it will idle fine til you turn on the auto idle.

My dad said I had it backwards, and therefore are having the same problem as you that it will not idle with the auto idle off.
@Zacharymc - based on my correction above, I'm not sure the carb is the problem (though I know it might be gummed some, it runs completely smooth at low (auto) idle). The problem is that it won't rev up - with the auto idle off, the throttle tries to open up which kills the engine. Unless a good idle might not rule out a carb problem...
1) Is there a way to test the diaphragm - put vacuum pump on it, time it for opening speed, connect it to power or ground (i.e. to rule out the sensor in the head)?
2) Is there any other thoughts on what might be bad? I'm not opposed to rebuilding the carb if needed, but do the kits come with instructions?
