So finally got it going , still not sure what’s wrong but ... changed crank seal and nothing , so started stripping it , took exhaust off and it was full of fuel , as the bike is new to me i May have left fuel on. , some how it’s flooded the bike , some things wrong but at least it runs now ... going to buy few new parts for the carb ,
at one point this week I had fuel coming out the overflow pipe so had carb apart about 3 times
