WH nut 553 #5 Posted May 7, 2013 See post above, there is a reason and sequence for trouble shooting What you are describing with the way it bogs and spits gas at full throttle tells me the exhaust is plugged Share this post Link to post Share on other sites

tunahead72 2,402 #7 Posted May 8, 2013 Before you do anything too drastic, check the muffler carefully for anything that might be plugging it up. I once had a mud dauber nest inside the muffler of a 2-cycle tiller engine, wouldn't run for more than a minute or so before it would die. Poked out the nest with a paper clip, and it ran like new again. Share this post Link to post Share on other sites
WH nut 553 #8 Posted May 8, 2013 If you dont mind the looks and a little more noise just put the salt shaker type on it and run. Share this post Link to post Share on other sites
