It takes me a little while to start but when I get done tinkering I get it started but when you shut it off and go to start it again it will not start, changed plugs but did not help. Seems like it gets intermittent spark. Thanks

 

>when it won't start...check the plug to see if its wet. It may be flooding
>an easy way to check for spark is...leave the plug in the engine, take off the plug boot and stick in another plug and let it hang next to the engine or a metal area so the threads are grounded...crank the engine. you should see spark jumping across the electrode. As far as it being intermittent, I'd make sure the pug wire is connected well at both ends.
>If it's been sitting for a long time, the gas may be bad. Drain the tank and try new super unleaded. (drain the carb too) Bad gas can foul out plugs and cause flooding real quick. It can also gum up a carb if it's in there too long.
>just another thought, dirty fuel filter?? I dunno
