    I have a 10HP little wonder blower that keeps bending the push rod. I always check oil before use and add if needed. It doesn't smoke and has great compression. I've changed the push rods twice and the head with new valves once and still have the same problem. Could it be a bad lifter? Any help or advice would be great. Thanks in advance.

    One of the valve guides may have slipped in the head...usually on the exhaust valve.

    That is what I thought. That or a sticky valve. That is why I changed the head (intek motor). Any other ideas? Thanks.

    I had one do the same thing. I cleaned the guide and put some loctite on it and tapped it back into the head with a socket. Once in place a punch scored the area around the guide so it cant work back out. Its been if for a long time now with no more bent pushrods.

    no timing needed when replacing push rods. just adjust the valves accordingly and should be ok.
