Welcome! :welcome2: What a cool project. Keep it gas, it will be easier and cheaper. Build it with the grandkids and make memories while learning them stuff.
Oh you’re using the yack grease rice fiber belt. There’s your problem you melted it and now it gummed up everything. Get a GENUINE COMET BELT!!! And clean up those clutches.
Is that the correct belt (COMET BRAND). What is the foreign substance on the clutches? Is it on the belt? Is the belt smeared all over the clutches shieves? Is the belt on correctly?
