Worst case, if it diesels or back fires like crazy I will just buy a new solenoid.
I won't say that snipping the end of the Anti-Backfire Solinoid is the right thing to do, but I will say that if you check any of the 5 Conquest engines I have, you will find that all of them have the Solinoid Pin Clipped off.
The last run at Busco before the Conquest took her final sh**, the throttle was sticking at wide open. It happened when we put a new driver behind the sticks and it was a mess. We took the handle off at Busco to look at it, didn't notice anything out of the normal. After reassembly, it has perm cruise control. The throttle does not return to idle when you release the handle, it sticks. (But it's the handle sticking, or the throttle cable - the arms and springs by the carb are operating as normal, something is sticking somewhere else) You have to forcefully twist back to idle. I was thinking if I took the handle back off, got WD40 down into the cable, and sprayed the arms and springs in front of the carb that everything would be ok. It's not! lol
Just a thought, If you tighten the little screws on the hand throttle assembly too tight, the throttle twist grip will not return freely.
So does the handle throttle control more than just the throttle valve in the carb? I ask this because there is maybe 1" of movement in the throttle shaft, moving the throttle valve from closed to open. With just a very small twist of the wrist, I can open and close the throttle valve completely. So essentially, the last 80% of my throttle twist does not move the throttle valve. If there is another function the throttle serves fine, otherwise something is funny.
The Throttle cable runs to a linkage on the Governer, when you pull the cable, the governor linkage moves. There is a spring that connects the governor linkage to the throttle linkage. If you are looking at it and testing while the engine is NOT running, it would appear as though there is not much happening at the throttle.
