Well I never got that bad. A little engine foam and she is clean again. Now the problem is that the drive sprocket on the motor keeps coming loose but I didn't have time to look at it. I think its the pin that hold it all in one place but not sure.
hmmm. thinking.... lots of loctites about all i can think of.
did you pull it off at any point? they have a key, and...i dont see how they can undo their own thread...maybe on the coast/compression braking, yes...but...iunno!
loctite! araldite! glue!
never had one come loose. the exact opposite... never been able to get one loose!
