Hi - I'm having trouble with the spin start on my both my buggy and my son's truggy - They both free spin, but don't engage the engine. I've checked the gears and they seem to be meshing and have replaced the one way bearings, but no success. Any suggestions would be appreciated.

Thanks,

What type of engines? You could have oneway in wrong or it could be slipping on the interior of the engine.

OWB's can only work in one direction as previously stated, also before replacing a OWB i would clean it with nitro blast/brake cleaner/denatured alcohol or whatever cleaner you have! then lube it with a couple drop's of ARO and give it another go!

seem's to work for me [&:]
