Re: 10 hp with a hiccup
Taz.... The hiccup problem, if it seems like that is coming out the carburetor throat, usually refered to as spitting back (sounds like a mild backfire), that would be due to a improperly adjusted slow speed jet. Instructions to adjust follows below.<br /><br />The jumping out of gear would be due to an improperly adjusted shift (leaning towards more reverse than forward), or worn shift lobes on the shifter dog and forward gear.<br /><br />(Carburetor Adjustment - Single S/S Adjustable Needle Valve)<br /><br />Initial setting is: Slow speed = seat gently, then open 1-1/2 turns.<br /><br />Start engine and set the rpms to where it just stays running. In segments of 1/8 turns, start to turn the S/S needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running. Eventually you'll hit the point where the engine wants to die out or it will spit back (sounds like a mild backfire). At that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting. <br /><br />When you have finished the above adjustment, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway.
