I like to make some comments about the Grubee. 1st off the 49cc china is a blast no engine problems. The gears scream until broke in. The gas tank cap leaks should come with a cap w/breather or cap off a good weedeater like echo. If it ever falls over make sure you check alignment. The rack is weak to sideways movement. Customer support is poor. I have a lot more to say but will leave you with this I love the setup despite the problems. I am working on some improvements. You Grubee boys need to return e-mails. Ok go ahead and slay me now.
