chr1969 1 #1 Posted March 8, 2011 :thumbs: I have A K301as on my tractor I use for plowing. Went to put it away today and it backfired after that all it does is crank its getting spark and gas. When I put my hand over the end of the exhaust it feels like its blowing and sucking. Could that presure release thing inside broke or something.The serial# is C001145 and spec # 475903 any help would be creat thanks Chris Share this post Link to post Share on other sites
