ok i rebuild my hpi .15 fe and has great compresion but wont stay running . when i prime the fuel about 3-4 times fuel starts coming from behind the flywheel underneth ? why is it leaking ?
 
You probably have a leak in the bearing that supports the crankshaft. Check it out, you may need to replace it.
 
how do i get that bearing out ? what do i look for i can't put no more money in this mill i should of bought a new 0.s.12cvrx o well .

i sucked dirt into the mill and scratch where all over the crank is this why ?
 
Well if you got dirt in your mill and you ran it after that you're gunna have a lot of damaged internal parts. Anyway, yes dirt in the engine could be part of your problem. I don't know how to get the bearing out cause i have never had to do it.
 
just put a screw driver (flat head) through the back of the engine and catch the race of the bearing and tap the screwdriver with a hammer. Dont be worried if you damage the bearing because your replacing it anyway.
