I thought I would try one of these MOTOALL carbs. I usually buy AUTOKAY but have a few bad ones lately. I buy DOZENS of these carbs and have tried them all. I just installed this motoall on a 10 hp snow blower engine and it runs PERFECT....not just ok....perfect. I ordered another just now and if it performs this well this will be motoall from now out. If you have an 8 hp engine the number must start with 63. If you have a 10 HP or 11 your part number must start with 64. They are jetted different and a 10 HP will not get enough gas with the carbs that have a 63....... part number.

It would have received 5 stars if it included instructions how to properly set the carburetor. I have included a snipet from another review that was left (thank you, it got mine running right away). Mine would not run until I followed this procedure. Small adjustments can be made as necessary.tank, DOH! Filled the tank and it fired right up. Note: this carb does not come with instructions, but it is pretty simple to setup. First adjust your Idle air screw on the side of the carb. Turn it in (clockwise) all the way, DO NOT OVER TIGHTEN, ONLY TIGHTEN UNTIL IT FEELS SNUG, then back it out 1.5 turns. Next, adjust the Main jet screw (the screw with the spring at the bottom/CENTER of the bowl) Turn it in all the way, then back out 1.5 turns. Start the engine following normal procedures and run at maximum throttle. At this point, the engine will probably run rough, turn the Main jet screw in until it starts to stall, you should be able to do this by hand, it does not require a screw driver. Then back it out slowly, the engine should eventually run smoothly, keep going until it starts to stall. Then the screw should be set at approximately the middle point in between where it starts to stall in each direction. Once the engine warms up all the way, adjust the Main jet again, using the same procedure. Once you are happy with the Main jet setting, turn the throttle lever down to idle and adjust your idle air/fuel screw using the same procedure that you used for the main jet screw. Clockwise until it starts to stall, then counter clockwise until it starts to stall, then set the screw in between, you should also be able to hear the engine reach its highest idle rpm at the center setting. Finally, adjust the idle speed screw SLOWLY counter clockwise to the lowest RPM possible until it stalls, then clockwise about 1/4 turn.This will get you running. Again thanks to the reviewer that originally posted this. Hopefully it finds more people being shared again.

Exact replacement for my snowblower.I like that it shows the measurements on the product's page. I measured mine to compare, and it was accurate.Comes with the gasket only, so don't throw away all your parts.After installation, it fired up immediatly. It just needs some adjustments for air/fuel ratio.

Was having stalling issues with an old snow blower that was given to me. I flushed the fuel tank and completely tore-down and cleaned the original carb, but it would only run for a few seconds, then stalled. Bought this carb and received it in 2 days (thanks Amazon Prime!). Installed it and because I'm a dummy, my snow-blower ran for a few seconds and then stalled, just like the original carb. After scratching my head and troubleshooting for far too long, I came to realize I didn't have enough gas in the tank, DOH! Filled the tank and it fired right up. Note: this carb does not come with instructions, but it is pretty simple to setup. First adjust your Idle air screw on the side of the carb. Turn it in (clockwise) all the way, DO NOT OVER TIGHTEN, ONLY TIGHTEN UNTIL IT FEELS SNUG, then back it out 1.5 turns. Next, adjust the Main jet screw (the screw with the spring at the bottom/CENTER of the bowl) Turn it in all the way, then back out 1.5 turns. Start the engine following normal procedures and run at maximum throttle. At this point, the engine will probably run rough, turn the Main jet screw in until it starts to stall, you should be able to do this by hand, it does not require a screw driver.

Finally, adjust the idle speed screw SLOWLY counter clockwise to the lowest RPM possible until it stalls, then clockwise about 1/4 turn. You should be all set at this point. Hope that helps someone out there!
