  1. Carb or brake cleaner and the diaphragms… If you get the cleaner on them, and they swell, set them in the sun for a couple of hours. It's only one out of ten times, that this does not bring the diaphragms back to original condition. If it doesn't work, it's likely the diaphragm was too far gone in the first place. Works for rubber hoses and other rubber pieces, as well.

  2. Gas trickles out of my ZAMA while setting, not running. Not sure what the needle's fulcrum arm should be set at, measurement wise. ……Any ideas? That's the only thing I can think of that's allowing gas to exit the carb without running. It's not a gasket leaking. It's coming from the fuel port/jet in the venture….Any help would be greatly appreciated.

  3. I took a 3in peace of 1/4 brake line grown the outside a little then put it over the jet screw taped it with a small hammer till it went over the jet screw bent the outher end at a 90 degrees that is my jet tool works great

  4. Great detail, and great camera work. Close up video really makes or breaks the teaching. Would like to see you  go thru the tricks to replacing the pin, spring, and arm that are held by the screw. Maybe it is straightforward but I am about to try it and have not seen anyone do it on these "how to" videos.

  5. I cleaned my carburetor and made sure everything was in place and checked the spark plug. And it still won't start. What's the problem?

  6. I have an old chainsaw, it won't start and gas comes out of the spark plug when I take it off. Could it be the carburetor? I haven't cleaned it yet.

  7. Great vid sir. Really enjoyed listening to you in this video. Very informative and easy to understand you. I'm waiting on a walbro carb kit to arrive and I'll be using this video while rebuilding it. Again, thanks for putting this together.

  8. I uploaded a video about my echo weedeater, could you please watch and tell me how to fix this problem, I don't know what that thing is called…. Thanks

  9. I just randomly watched this last night, then today coincidentally found a free unit that needs carb work – Thanks for sharing your know-how.

  10. My dad's working on a friends weedwacker, some Craftsman one, and it requires those special spline idle mixture tools. What did you use to bypass that or where would you get them from? Thanks!

  11. Tip on the fuel line removal. Grab it with pliers where it sits on the brass area and twist a bit to break free and wiggle it off. Less chance of breaking.
