Need some help with my blaster!

[national425ex]

I was letting my cousin ride my blaster over the weekend and it was running good. Had good compression and started on the first kick when we began to ride. It was even running great about halfway through the ride. Then all of a sudden the engine killed and now there seems like there isnt any compression in the engine. I can push the kicker down with harldy any effort. I cant get this thing started to save my life. We even tried push starting it with no luck. I just had it rebulit sometime in Feb. Does anyone know what could be wrong?

Sounds like a hole in the piston maybe... probably over heated it.

it was running pretty hot

time for a rebuild again,sell it once its back together its going to keep blowin up it the nature of the beast with 2 strokes your always jetting or your always blowin up so let it be someone else's head ache you know what I'm saying just let her go.

dont let her go have a custom piston MADE AND RUN DUCTING TO FORCE AIR ON TO THE MOTOR AND BREAK IT IN RYT

Bore the motor out and get a wisco piston

sounds as tho you may have smoked the rings and/or piston. since its on a fairly fresh bore/build you may be lucky and its ok but, i'd check the tolerances for safe measure.

i'm thinking you may have a jetting issue or air leak and leaned it out for it to happen suddenly as it did. when you go back with it i'd recommend that you perfortm a leakdown test to make sure you dont have an air leak at a seal or other.if that checks out then its most likely a jetting issue and you should do an across the board plug chop after ther initial break in.

redridder, im curious as to why you would be so qwik for him to just get rid of it? :huh

blasters rock get it ported to and mill the head to boost comp a lil bit
