I have a 48cc Grubee. I am just about done breaking in the engine. During the 2nd tank of gas the bolt that holds the small bevel wheel on came loose and drilled a hole through the cover. I took a bolt from a scrap engine I had laying around and replaced it. Now the second bolt has stripped as well. Fortunately, I heard it rattling around before it could cause more damage. Has anyone else had this problem? What should I do? Thanks for your help!
