Well I found the problem. Thanks for all the advice here, you guys are the best. I had my 6 year old crank the engine while I put my hand over the airhorn on the carb...suck...suck...suck...suck...blow...blow. That didnt seem right and there is the answer to the gas blowing back up through the carb. I popped the valve cover and turned the engine over again. didnt really see anything until I looked at the push rods. #5 and #6 push rods are bent and out of place and obviously not allowing the valves to open and shut properly. Whats my best way to deal with this issue now?????
