Questions?? jammin' jpx .28 not turning over???????!!!!!

i got a jamin .28 for my mugen truggy and i have a ofna chrome top 12v motor with a gel pack. i let the charger stay on charge for about 10 hours. it has 1 gallon of fuel through it.

It might be that the engine is still not fully broken in.

What your experiencing could be the "pinch" at TDC.

If it has a true gallon through it, a strong starter box should have no problem turning it over when cold though.

The Jammins are very tight motors. My dad's .21 has over a gallon on his and he still heats his up before starting. It's tight still.
