Re: Now I own *two* DAX GT50r motors........
Sounds like you have no spark to the plug....or maybe a timing issue which is probably unlikely, but always possible.
Yes as John the Chimp mentioned check that the gap between the coil and the flywheel is about the distance of a bank check, this is a good distance on most small engines IMExp.
If starting fluid gets zero response then I say you have an ignition ploblem.......
bad wire? bad plug? bad coil? kill switch wire grounded? air gap between coil and flywheel to wide? check all of these and see what you end up with.
Make sure all engine bolts & nuts are tight and all gaskets are sealing good also, cant be any air leaks on a 2 smoker.
I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
