Thanx Calvin, I don't think that temperature is the main culprit, since the the recent couple weeks that i tryed to start it was in the high 50's and last spring when i bought  were it was warmer.  I wanted to use the tractor as a &quot;working' tractor and to keep using ether would be a little inconvence. I was also woried that over using the ether would damage the engine, however by your testimony of using ether on your 770 i have some ease from that fear.  

Though the engine does have alot of hours, about 6 thousand, and I think that low compression might be the problem.  
And to fix that I would need to rebuild the engine, correct?

Also I was reading a post on yestardaytractor with a guy with that sounds like the same problem.  And he rewired the ignition and starter, to give the starter a little power the starter it lacked on the old wireing.  
What do ya'll think about that as the problem?
