Quick story
Old bike frame broke while riding. The frame had snapped right above the rear mount due to a small crack that got worse after a month of engine vibration. (Vibration isn't bad, I used the frame with knowledge of the crack) During my ride the back wheel seized and I slid to a stop. The engine had rotated to the left around the rear mount. It was still attached to the rear and it rotated and touched my left knee. So I just swapped over to a huffy cranbrook
STATS
80cc motor running Lucas Semi 20:1 ratio was running beautiful
#65 jet ( I have 60-80)
After a few rides after buying this engine i heard a rattling, the small clutch gear bevel screw had unscrewed and was sitting in the clutch case cover. I screwed it back in very tight and it had unscrewed again and boogered up the threads. I ordered a new bevel gear, screw and woodruff key as well as a gear puller.
MY PROBLEM
Engine mounted very well, looks phenomenal. Not a fan of coaster brakes so I am adding hand brakes form my old frame. The first start on the new frame produced a tremendous amount of smoke ( my initial thought was fuel in the engine still) With alot of smoke it was barely any power. I moved the clip to a leaner setting and i got a little more power. Im thinking of changing the jet again, maybe its still to rich? IDK. Im lost. I was getting tremendous speed and power before my old frame cracked and the engine shifted over. I thought it was my throttle assembly because it's old and I boogered it up getting it off the old bike so I ordered a new one.
QUESTIONS
Did I booger up the crank shaft when everything shifted so hard?
Why after remounting the engine did I start running so rich?
Could this power loss be caused by the bevel gear and or woodruff key?
Any help would be greatly appreciated. My daily driver went from 38mph to a wopping 10mph.
I can provide pictures and video upon request.
THANKS!!!!
