RBM 12 #1 Posted 5 hours ago Hello...I have a quick question regarding my air filter on my kohler k301/ Wheel Horse 12 automatic...I was recently changing the air filter and I started it while it was off and realized it ran much better even with the new air filter...what should I do about this? Is there a high flow air filter? if so what should I do? 1 Share this post Link to post Share on other sites

A new clean filter should be more than adequate for the engine. Do you use ethanol fuel? How old is the fuel line? Fuel filter? When was the most recent carburetor rebuild and total fuel system clean out? 3 Share this post Link to post Share on other sites
