    OK guys, here is my problem. 1 year ago I replaced the engine on my walkbehind. I replaced the old B&S engine with a new B&S engine, it is an Intek, 13.5 horsepower, I use the mower 2 times a week and it was fine until recently. The problem is I run the mower for about 1.5 hours and then it boggs down and finally cuts out, like it's out of gas. I then let it cool down for an hour and it will then run another 1.5 hours and does the same thing. I tried gasoline additive already. Any help would be appeciated. Thanks.

    Might be a weak coil breaking down when hot..
    Do the easy stuff first...Tune Up...Check valve adjustments...
    Not sure what kind of warranty Intek engines have on commercial walkbehinds...

    I was thinking it had something to do with heating up. Thanks for the advice.

    Check your gas cap and make sure it's venting properly......
