Re: one week old motor wont start
i thought the same with my motor, exhaust and oil but it was infact the cranckcase seal on the magneto side that was leaking onto the exhaust....just take off the magneto cover and if there is oil in the case then you need to replace the shaft seal - a common problem
the motor looses pressure in the crankcase when this happens and could be giving you greef? good luck with that.
Going fast is easy it's stopping where our greatest challenges lie !
