I had this very engine installed on a GP Giant Big Stick and Scott told me to use the largest metal Du-Bro mount. I belive it is the one for 120 4 stoke engines. They are a little expensive, but will worth it. Makes the installation just like a glow engine and the shock absorbing is a nice feature. Take a look at the pic. I had trouble getting mine started and Scott took it back and I upgraded to a 42cc w/ei I plan on using on the giant big stick. You will need a starter that spins this engine at least 1000rpm to get it started, but once it is started you'll love the power it has.

Thanks
