Default Wheel spin at idle

When the wheels spin at idle it means your idle screw is to open, correct? Or is it the LSN that is to lean?

It could mean your idelling too fast, which could be either the idle screw or the low end needle. Get the idle consistent, so its not bogging or dipping up and down with the low end needle, then alter the speed with the idle screw.

Great little vid here

Or it could be your clutch is dragging. Either a bearing going bad, not shimmed properly or broken spring. Just something else to look at.

It is a new clutch, so I may be able to eliminate that. I will play with the needles some and see if I can get it to drop. It could be shimming on the driveshaft. I will report back tonight.

You could try pinching the fuel line 1cm before the carb after your engine warmed up for 30seconds. If the rpm's do no raise the LSN is too low. And the engine should bog when you accelerate.

If the LSN is set right, just screw out the idle needle.

the pinch test is not that simple this is where people get mislead full operating temperature make sure excess fuel is out of the crankaseafter warmup set vehicle on something like starterbox so it wont fall rev a couple times to clear out them after second or third rev as soon as it is ti its idle pinch the lineif it revs immediately too lean richen low speed try againshould be approximatelt 3-5 seconds before reving when line is pinche,monty if you read thiosi and I am wrong plz advise but this method always worked for me
