I'm a new member I recently purchased a diamondback bike with a GX35 Honda spindle drive on it. The engine was not running due to cam timing prob.I set timing the best I could with out any info and got it running,but it seems to be a little sluggish. Hoping some one could shed some light on the method for setting it correctly. I'm a fork lift mechanic by trade I have many years of experience with small engines from 8 years of lawnmower shop employment and 11 years in rental yard as mechanic. I have many gas powered scooters and now 2 bikes.
