I am looking for the gears of a skyfire gearbox from the huashang 4-stroke kit. so far I have tried

1 lawn mover repair
2 transmission repair
3 motorcycle repair
4 motorized bicycle shop

tomorrow I am going to a gear shop

what happened was that the bolt that retains the clutch bell, came loose and broke some teeth and a feather key. I got that fixed and the next thing that was wrong was the chain sprocket on the gearbox was a little too thick for the chain and the chain seized against the engine block and sprocket, braeaking another key and some teeth on the the gears. I have never seen broken gears that look like this before. its almost like pot-metal, reminds me of the matarial that the case is made of.

well everything is in perfect conditons now but the gears are ruined. I even fabricated a simple spring loaded chain tensioner. I could get another gearbox with the same quality but I would rather get better quality gears instead.

so if anyone can help please respond

thank you and good luck.
