ya me to, I took my old motor out and was checking it out good. After doing a leak test with some soapy water i found a huge leak around the seal in the front bearing. I would assume this is the biggest problem. Other than that i could not find any other leaks. Was some nicks and marks in the top of piston and the bottom of the head. Could this be pre detonation or something or maybe a piece of a glow plug element went down in there? No marks in the sleeve though. Oh and what should my carb be set at for break in?

Ok thanks. Do u think that front seal on the front bearing leaking that bad would make it hard to start and wont stay running? Everytime i let off the gas after fighting to get it started it stalls imediately, no matter the tune or idle adj. i tried.
 
More than likely. Front seal leaking bad is in no way a good thing and i would imagine that air is getting through as well as oil. Time to break it down and replace the front and rear crank bearings and seal up the rest of it while your at it.
 
ok, i may do that for a spare layin around. I hooked a piece of fuel ine to the carb and put some soapy water around the seal, and it looked like a geiser of soap bubbles. And with not much air preassure either.I might spend the twenty for new bearings and try it out.
 
So i got the new motor in the mail thursday nite and dissasembled, sealed and reasembled thursday nite and finished it up last nite. I am now on my sixth tank and everything seems to be goin pretty smooth so far. No fouled glow plugs. Did get stuck in tdc, but i put the heat gun to it and loosened right up. Gonna take some time today and start to get it tuned in. Already runs better than my other motor and its still not tuned for performance. Thanks to all u guys for your help!!!
