I just purchased an 04 blaster from someone that performed a top end rebuild and gave up because once they got it together as soon as you hit the throttle it just cuts off. So far I cleaned the carb, replaced the reads, and performed a compression test. I found that it only had 60 psi. So I pulled the head and the jug and found that the piston and rings are in great shape the cylinder walls look good. Any ideas I will try anything to fix this thanks
