finger over the exhaust never works for me so i pull the tubing out from the exhaust and blow into it to prime the engine. a more direct method. Just keep track of how much fuel travels into the carb when you blow so it doesnt flood.

Take the glow plug out. Turn the engine over, does fuel coming flying out of head? Probably good idea to wear eye protection to keep fuel from getting in your eyes. If you see fuel coming out, then you are getting fuel clear to the plug. If not, then you are not getting it through your carb into the crank and up. So, if you are getting fuel, then turn in the lsn needle and it will probably start. My guess is the bottom end is too rich to start.

How many gallons of fuel do you have through it? Also if you had fuel sitting in it for some time it may be gummed up and the carb may need cleaning.

Just saying a couple things to check.

fuel is defently getting into the carb and into the crank if i prime it and pull with out the glow plug in i get fine mist of fuel come through. i have not checked the low end needle setting yet , but it did run last time it was out . i have a feeling it may be something to do with the clutch as it is turning the wheels whilst trying to start it . going to strip it down tonight and see if that could be the problem

If the wheels are turning, then that is a good indication of the clutch bearings are bad.
