My little project is finished.
The power to weight ratio of these Japanese motors is phenomenal.
This is a 21 cc motor but has all kinds of torque.
Weight is under 23 lbs, the extension is built to go inside flighting.
So it would likely save 3 pounds if take out.
Will post a video of it drilling later.
The China carb wasn't a perfect fit....but the old carb had a hidden single jet. The NEW carb came with primer and visible hi speed jet, but hidden low speed jet.
How can you go wrong for $25.
Runs perfect after warm up.
Next project will be mount on back of SB Assault.
