I'm going to rebuild the top end and bottom end with some ?????????????????

[0_o]

Ok, when i bought my blaster the seller told me it was "bored 20 over" can i get any bottom end kit and top end kit? and will this get rid of most of my problems i've been having?

or is there one big kit i can get?
or what else should i do to have a new engine trouble free

new parts wont fix your problems if its jetting thats off or an air leak.

that said ...yes you can get new top end kits and crank kits, but there is no point of replacing parts that dont need to be replaced. the crank and rod may be great and you just need a fresh bore and piston kit. Or the top end maybe fine but you have a worn crank bearing/seal....

what are your problems? Never mind, i just read through your posts. Do you have air box vents? Because I had a vent fall through the hole and it didn't let any air into the carb. You also could've made a rut in your piston (which will obviously lose compression) if your gas isn't clean, mixed right, with decent oil, and do you still have the pre mix on? Because they often fail and run ya lean.

i still have the premix on and i mix it with castrol 2 stroke 4oz with one gallon, i dont have any air box vents i took them off and disconnected the intake to put starting fluid and nothing.. the only thing i have yet to try is to change the plug,

it works if you pullstart it with a truck though :-/

Sounds like you need to test the compression. 120-110 psi is ok. Less than that and you need a top end rebuild.

if the compression is very low will that fix my problem though?

If my piston waas 20 over what size should I get there is a whole bunch

diagnostic work first my friend.

You need to do a few things before you go ordering parts and replacing pieces. You need to do a compression test and a leak down test. If you have a leak and it caused your top end to fry, you replace the top end it's just going to fry it again.

If your compression is low, you MAY be able to re-ring and hone the cylinder. There isn't any way to tell without pulling the top end off and measuring the parts.

i think you should try a new spark plug first br8 is the one you want
