ok just did a cold start of my blaster.hasnt been started for 3 weeks. took about 6 kicks with full choke to start. very unusal/ usualy starts on 2 kicks with half choke fnallyit does start it smokes ALOT more than it should and smell ike something is burning.i mean smokes goes everywhere. then it dies on its own. will try to get a video. just put a BRAND NEW spark plug in to. do i need to get the top end rebuilt?
 
A leak test and compression test will tell you a lot and both testers are very useful tools to have.
A leak tester you can make your self for ~$10-15 and a compression tester can be had for ~$20. I highly recommend everyone to have both.
 
i havea compression tester. the blasty has been running on 95 psi for 4 years now no probs. ok IGNORE THIS THREAD. it scared me but i let it idle and the smoke went away back the the regulars blue smoke thansk for your help though.
 
95 is REALLY low. A good condition, stock head, top end should be ~120psi
You need to have that checked out for piston clearance.
If its out of spec that top end is a ticking time bomb. Piston will be able to move too much and could break the skirt off.
 
im gonna pull the motor out this witer and tear the top end apart and see when i had it apart a year ago it looked perfectly fine
