    Had a kid message me on a lawnmower he got to play around with and fix. He asked where a spring went, likely for the governor, and I couldn't find a good clear pic. Your video gave him a perfect show of how to mess with the carb and where that spring went he sent me a photo on. Most people move camera's around so much, you can't see details. Good job!
  • Excellent video! all fix videos should be set up just the way you did. No fluff, clearly showing what you're doing, and nicely marked.
  • It's nice us viewers don't have to fast forward on this one - so boring watching somebody loosen or tighten a bolt in real time. Excellent production Thanks!

    Good job sir, thanks. Fixing an old mower for gift to a new couple that moved in neighborhood. I noticed he rented a mower yesterday.

    You saved my arse brother, even with Stabl it wouldn't start. Carbs are so cheap these days it was easier to replace and then use my ultrasonic for the other that came off to replace next time. This video was perfect too. Right to the point, no mucking about. I added an inline fuel filter since the replacement came with one.
  • thanks Jim. I bought a mower for $25 an the spring and rod that attaches to the governor was a-danglin', and you showed the location !

    The carburator choke and valve is the same and is located on the out of the carburator before the intake pipe. The engine governor controls the carburator choke via a small rod. The second rod w/spring is for set up the RPM engine. The carburator doesn't have any set up. Use only super 91-93 gasoline w/o ethanol. The ethanol produces the gomme. A valve on the gas pipe from the tank to carburator will be a good ideea.
  • Looks straightforward. I'll be swapping out the Tecumseh 640017B Carburetor on my Whisperjet leaf blower this week and this was a good primer. Thank you!
  • Parts are available to rebuild these carbs. Very cheap easy to do , nothing runs like a QEM carb.

    Installing the back side nut is the hardest part😄
  • Hello, That red line sticking out of the carb hole. I recently cleaned up the carb but when I went to out gas back in it gas immediately started leaking out of that red line sticking out of the carb hole. Any advice?
  • @bbtg
    Just wondering, is it possible to clean carb. Or replace??

    Hi, please tell me where I can purchase this CARBUETOR and part number ,thank you
  • I have fuel leaking into the air filter from the red tube of the primer bulb. Any idea why it's doing that?
  • @tonygonzalez9167
    I have a lawn mower Craftsman shuffle pills I got a question it runs and dies out after little time what can be the problem
  • Is it normal for one of these carburetors to have gas leaking out of that red straw into the filter and then out of it? I bought a 4000psi water pressure sprayer dor 6 bucks and I can not figure out if that is normal or not or why it would do that.

    Hi great job there you know the cover / case that goes over the pully area do you know what type of screw or bolt that holds that plastic casing on?
  • @mrBDeye
    Can you tell me where the part number is located? I have the exact carb with red primer bulb on my Earthquake Rototiller.
