ya hit it with heat gun while its sitting on the box. there isnt many motors that you will be able to turn over by hand when they are new.

also just follow the instructions for breaking it in

i dont have a heat gun either but a hair drier gets the job done, i can get my engines heated up to about 180-200 degrees.

Do a search for Competition Heat.....it's the best money you'll spend, and your motor will thank you for it.

What starter box are you using? I've got the blue top Ofna....the one that you can almost start a small block Chevy with, and I had a little difficulty when I was first starting my motor.

You're likely just getting the top of the head to 200 deg., not fully saturating everything to get it to expand. Try a lower heat setting, but leave it on the motor longer. Once everything expands, it'll be easier to start.

Like I said though, look at Competition Heat. I haven't used my heat gun once since I bought my heater from Eric...good product.

When they are new I have had them get stuck at tdc, turn the flywheel with a screwdriver to get it loose and be sure its at bdc and heated up before you try to start it again. The flywheel does spin freely up until it gets to tdc doesnt it?

Good point. I was assuming that it did....if not, you've got something bad going on.

Mine was the same way, get it warm, and make sure your starter box battery is in tip top shape (charged)

It will go, just takes a bit to break in a motor.

So I finnally got it started I had it running for about a min and pulled the glow igniter off and it died. And I haven't got it started yet. As for the starter box it's a cheap one. I didn't think it made a huge differance with what one you got. I probably should get a good one. Ne ideas?? And my motor does turn really hard at tdc
