Rcmk 29.5 is in, rear dom on, 990 carb, and belt drive. Did a test run last evening and I got say holly crap! It was a quick short run as im still waiting on a few parts to complete. The engine is rated at 6.5 hp and it shreds grass better than my lawn mower! Def think it was a good decision.! Once complete I will work on a vid.
