Re: soft seize?
why are you trying the electric start?
Kick starting always works better.

Re: soft seize?
Greetings:
Sounds like the overheat warped the cylinder. It does OK until it warms up, then the piston grows too fat to get by the tight spot. Super-accurate bore gauge could confirm. Probably needs a bore to the next oversize to run now.

Re: soft seize?
are you using just the stock oil pump to lube the motor?
Nothing like getting stroked!

using a stock oil pump and premix. i have a temp gauge now but that doesn't help the damage that is already done.

Re: soft seize?
is the pump tied open or do you have the split cable to it?

Re: soft seize?
Don't you have two engines now?
Send them both to me....and I'll send one back, boost port matched and running.

Re: soft seize?
I would seriously be sure that oil pump was working, and if you haven't primed the oil lines all the way to the intake, it's just like you described. Seized up right after starting.bakaracer wrote:are you using just the stock oil pump to lube the motor?
You can try it with all premix and just loop the pump back to the reservoir.
