    Thanks Fix. The valves are supposed to be at .004" so my gap is huge. Could it being this far out of adjustment be causing my problem? I would just adjust and try it but I tore the gasket when I was taking the cover off and will have to wait until tomorrow to get another one. The carb doesn't have any adjustments. In the mean time if there is something else I can check I would like to so it can be ready to go first thing tomorrow morning. Thanks

    If that is an overhead valve engine with stamped steel or aluminum cover you should be able to use "permatex gasket maker" on it . Available at any parts store. That could very well cause popping and missfire.

    I adjusted the valves and used the gasket maker last night. Fired it up this morning and it sounds much better. It is still smoking a little when I engage the blades, but it is definately usable. Anyone have any ideas how to eliminate the smoke?

    Just run it a few days and see if it doesn't stop with the smoke.

    How much smoke are we talking here? A small haze or a cloud?

    I figured out the problem. When I took the main jets out I didn't realize they were different. One was 136 the other was 140. I switched them and now it runs great. The other change I made was on the gasket between the carb and air filter. The gasket provided by the dealer blocked off 4 little ports. Not sure what they are but I cut the gasket to free these up. Not sure which change made the difference but it is running great. Thank you all for your help.
