Re: problem with 6hp evinrude
Trail,<br /><br />To reply to THIS thread, just goto the bottom of this thread and click on "Post a Reply" . Now that we've got that handled, lets get back to your problem....<br /><br />You're other thread said:<br />--------------------------------------------------------------------<br />Trail <br />First Mate <br />Member # 34307 <br /><br /> posted October 17, 2003 06:52 PM <br />--------------------------------------------------------------------------------<br />Yes, i did check the advance timing and it seemed to be okay it was in between the two notches.. When i choke it on accelatoring it does not fall on its face.. I can't understand why that carbeutor idles fineand the other carbeutor i stick on it will not idle but accelerate just fine..Could it be something to do to the fact that the one carbuetor is off an 8hp motor<br />very confused Trail <br />---------------------------------------------------------------------------------<br /><br />Seems like you have 2 carbs with different problems. You're original carb may still have a blockage in the low speed idle circuit, that's why it won't idle.<br /><br />The new carb , from the 8hp Rude, may have a blockage in the High Speed circuit.<br /><br />General advice for either carb:<br /><br />Remove and disassemble carb.<br />Remove needle(s) and spray all orifices with carb cleaner. <br />Remove high speed jet ( if so equipped) and liberally spray with carb cleaner<br />Invert carb body and check float level.<br />Check float valve for proper seating.<br />Blow out all passages with compressed air. <br /><br />The fact that you can choke the 8hp carb and get full power without stumbling indicates a clogged high speed jet/circuit or the float level too low.<br />Also check the carb to intake manifold gasket, be sure it's not sucking air.<br /><br />Adjust carb needle(s) as applicable:<br /><br />Depending on which carb you have, pick one of the following.<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<br />turns, start to turn the S/S needle valve in. Wait a few seconds for the engine to<br />respond. As you turn the valve in, the rpms will increase. Lower the rpms again to<br />where the engine will just stay running.<br /><br />Eventually you'll hit the point where the engine wants to die out or it will spit back<br />(sounds like a mild backfire). At that point, back out the valve 1/4 turn. Within that 1/4<br />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<br />them again unless the carburetor fouls/gums up from sitting, in which case you<br />would be required to remove, clean, and rebuild the carburetor anyway.<br />--------------------------------------------------<br />(Carburetor Adjustments - Two Adjustable N/Vs)<br /><br />Initial settings are: Bottom high speed = seat gently, then open 1 turn out. Top slow<br />speed = seat gently, then open 1-1/2 turns.<br /><br />Setting the high and low needle valves properly:<br /><br />NOTE: For engines that DO NOT have a shift selection, obviously there is no<br />NEUTRAL position. Simply lower the rpms to the lowest setting to obtain the low<br />speed needle valve adjustment.<br /><br />(High Speed) Start engine (it will run pretty rough), shift into forward gear, take up to<br />full throttle. In segments of 1/8 turn, waiting for the engine to respond between turns,<br />start turning in the bottom high speed needle valve. You'll reach a point whereas the<br />engine will either start to die out or spit back (sounds like a mild backfire). At that<br />point, back out the needle valve 1/4 turn. Within that 1/4 turn, you'll find the<br />smoothest setting.<br /><br />(Low Speed) Slow the engine down to where it just stays running. Shift into neutral.<br />Again in segments of 1/8 turns, start to turn the top needle valve in. Wait a few<br />seconds for the engine to respond. As you turn the valve in, the rpms will increase.<br />Lower the rpms again to where the engine will just stay running. Eventually you'll hit<br />the point where the engine wants to die out or it will spit back. Again, at that point,<br />back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed<br />setting.<br /><br />When you have finished the above adjustments, you will have no reason to move<br />them again unless the carburetor fouls/gums up from sitting, in which case you<br />would be required to remove, clean, and rebuild the carburetor anyway.
