bhf, i wonder if you are having starter clutch problems.
Have a look at this thread.

Thanks for the link. The Engine have been sitting with oil in for about 8-10 years and not running before i got it. The oil i got out off it were new but dont now what oil it was. I have put mineral oil 10w50 in it. Can the oil be some of the problem? I was told that bike ran before it were taken appart for nealy 10 years ago.

My experience has been that if synthetic oil is being used where regular oil was used for years, then starter clutch problems can develop. Compounding this is the length of time the bike has sat idle. If you can get it to run somehow and good and warm with regular oil - it might start working enough to use. I'd try running as light of oil as you can to try to free any sticking parts in the starter clutch, but the rollers and springs can get pretty sticky. If that fails, it'll have to come apart to clean and/or repair.

What about a little kerosene or Marvel Mystery Oil or even ATF in place of a half quart of the motor oil Dave? Would that be safe to try do you think?

My thoughts, Nils, are that would be OK PROVIDED the engine was loaded very lightly for a short time. Might do the job. As a sidebar to that, the old-timers would do something similar to that to clean out the old flatheads -- let it sit and idle for 1/2 hour with straight kerosene in the crankcase. Then, drain, and refill with normal oil.

Well in that case I guess I'd try it in an otherwise good-running engine before I tore it apart.

Would that work with an engine, that does NOT have ball bearing rod journals?

Don't honestly know, Mike. While it might, I certainly would not put any load on it. I have never done it. But, I knew several old-timers, including an uncle of mine, who did such a thing. Just thought I'd mention some historic 'trivia'.
