perry 82 #1 Posted September 15, 2013 Tucky problems - watch the video . engine runs up & down . just put this replacement engine in and it wont cooperate . The carburetor i am using came off the original engine that ran well until it blew a rod. The carb is cleaned and been adjusted numerous times . tried two different fuel pumps as well. I have had this engine running smooth a few times but not for long. I have also changed the head & gasket and still no change. fuel system has been flushed twice and fresh gas added i bought today.

illinilefttackle 399 #2 Posted September 15, 2013 Perry- just a guess but I'd say its running too lean. Richen up the main jet until it smooths out-governor is compensating for rpm drop. Maybe silghtly low float setting-Good Luck-Al Share this post Link to post Share on other sites
