Re: engine smokes

Does it smoke at all RPM's, speed, ect? If so, it's time to check the compresssion and see what's going on inside the motor. If just at idle, that is probably normal..<br /><br /> Fuel Mix

Hi John <br />It seems to me I was reading a previous post of yours where you were having trouble adjusting your carb or getting properly reassembled. It sounds as you my still have a problem there. You can allways expect more concentrated smoke while running in a test tank.

Re: engine smokes

Also. while you have it in that barrel, I would do a decarb. As Alcan said, they always smoke more in a barrel(Sometimes alot more). Good idea to take it out and run it on the lake and blow some of that cr*p out of there. Here's a link for decarbing:<br /><br /> web page
