Re: quits after idleing
The motor dying at low speeds and only shifting without dying at higher speeds sounds like it's either leaning out (wrong carb setting) or has a dirty carb. (You are running 50:1 gas

il mix, right?) First, try adjusting your carburetor. Hopefully this fixes your problem. The slow speed needle valve is that Rich-Lean knob you see. (instructions below) Second, try cleaning your carb thoroughly (soak it 24 hours, blow out all passages with compressed air, remove metal plug to clean out idle passages and replace with new plug) and rebuilding it with an OEM carb kit. <br /><br />Thank Joe Reeves for these awesome instructions!<br /><br />(Carburetor Adjustment)<br />(J. Reeves)<br /><br />Initial settings are: Slow speed = seat gently, then open 1-1/2 turns.<br /><br />NOTE: For engines that DO NOT have a shift selection, obviously there is no NEUTRAL position. Simply lower the rpms to the lowest setting to obtain the low speed needle valve adjustment.<br /><br />(Low Speed) Slow the engine down to where it just stays running. Shift into neutral. Again in segments of 1/8 turns, start to turn the top 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. Again, 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 adjustments, 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.<br /><br />Good luck and report back with your results! An OEM service manual for your motor will be a great help with maintenance and adjustments.<br /><br />Kev
