I have had this machine running and put about 4 hours on it but it would not idle great. Would fluctuate between 700 & 2000 rpm and usually quit at the low rpm. Spark plug would carbon off and have to be cleaned. Throttled up nice and ran good in mid and high range. Machine then quit and wouldn't restart, couldn't get it to fire. Checked everything, had spark, gas, etc. Thought spark may be weak so ordered a new coil. Machine sat for 3 weeks waiting on new coil. Installed coil and machine fired right up. Idled nicely until it warmed up and then rpm's were all over the place. It quit after about 20 minutes and then would restart. If I let it sit for a few days it will start but won't idle.
Fuel/air mixture screw does nothing, can be screwed out or in and no change in idle. Only way to keep it idling is to turn the throttle screw way in and have it revving over 2000 rpm.
As this unit sat for close to 14 years I have replaced the pulse pump, carb, CDI, spark plug and now the coil.
What am I missing? I have done all the ohms checks on the stator, pulse trigger, etc and they are all good. I've took the carb apart to ensure it was clean, reset the float to be leaner as plug was indicating it was running rich. Didn't make any difference. Don't know where to look next?
Also can anyone tell me what these wires are for that come off the bottom of the carb (see pic).
Thanks for the help
