Re: Rebuilt the Warrior and still no compression???
Don't know much about Warriors (although I do know I'd like to have one), but are you sure the valve clearances are set right? If they are too tight, a valve may be "not closing". You did set the valve clearances after rebuild, right? Does a Warrior have a built in compression release for easy starting? That could also be a cause. An old trick I learned from my brother- whenever you have a 4-stroke head off of an engine, turn it upside down and pour gasoline (don't tell OSHA) in the pocket (what else do I call it? the combustion area of the head), let it sit a bit, and look for gas leaking down into the intake or exhaust ports- this gives an indication of how good your valves are. A little leakage is normal, but a constant trickle or flow is not good. Hope you figure it out. Ed.
