Hey guys; So I've been trying to get this predator to start.. Rode beautifully for a bit, an one night just died out... I've checked the Pistons, did the timing, cam, carb clean/adjusted cleared the lines, ran new gas, an even cleaned the combustion chamber. It still refuses to fire. Spark is fine as well. There's plenty of compression, yet it won't start unless I pop start it. Even then it wants to dog out right away.. any ideas?
