 20 hp loss compression Hunted saturday and my go devil ran like a dream. Sunday I launched and it wouldnt start. Got it started for like 2 min and died and never started again. Normally the compression is so hard that if u pull in the wrong spot it will rip ur arm off. Sunday I could pull and pull with no kick back. Anything I should check first thats easy before I completely rebuild the engine?

Re: 20 hp loss compression Check the valves sounds like rockers they just need adjusting.

Re: 20 hp loss compression Found out a pushrod had come off the rocker arm. What could be the causes of this? Does it just happen some time?
