Hi, im working on a buddies lt80 that dont run. I have figured out what it is i think. There is a black spacer in between the reed cage and the carb. Well the reed cage has a groove around it for a o-ring(witch is missing) and then the black spacer has a groove for a o-ring then the carb bolts go thru it and bolts the carb to the cage,with the spacer in between the two. Well it would not run but i did get it started and i think it was not making a good seal do to not having the o-rings in place. So my question is there suposed to be 2 o-rings?

Next is i have seen this thing run in the past and noticed a loud grinding type noise comming from around the rear gear box area. Has anyone ever heard of this before? It only does it when the ride it. Once it get it running ill be able to locate the noise better.
