Craftsman 16 Inch

Hi all,

My buddy has a Craftsman that isn’t running right. It idles so high that the blade turns, but when we adjust the carb to bring it down to a good idle it’s underpowered and doesn’t cut.

Thanks,
Will

    There is two adjustments for idle speed on most of these Poulans. One is a mixture adjustment and one is idle speed. You could adjusting the mixture instead of the idle speed. Depending on the actual setup it can be another problem like an air leak that causing the high idle. A few these saws I need to enrich the idle mixture to slow them down.
     
    We really need the Craftsman model number as they have started using some MTD engines to see how the little chainsaw is setup.
     
    Being a two cycle it would preferable you let a good two cycle tech check out the chainsaw as the problem can be caused by multiple problems such as a simple adjustment, carburetor that cleaning and repaired kit, or even leaky crankcase seal. Either one of these can lead to lean burn problems and you can destroy the engine running it too lean. The same result of straight gassing one except it takes longer to do the damage then it is a new saw.

    It is also important to note that if your carburetor has both a L speed and H speed mixture adjustments that the L speed mixture will affect the H speed mixture adjustment. Initially you set the L mixture for best speed and then the H mixture. Even then when you slow the idle speed you will probably need to fine tune the L and H mixture adjustments again.
     
    On some engines it is required to enrich the L mixture to slow the engine when the Idle speed adjustment does bring the engine speed down to specs. Also it is the same for the H mixture especially on Stihl chainsaws so they don't exceed the max off load rpms.
