good luck... but your number says craftsman all over it. have about go to sears and type in that model number... your Tecumseh number would be like an LV160 or something similar

You can find a free diagram at www.sepw.com, use the part number of the carburetor as a model number under tecumseh brand lookup. Your carb part number is 640065a.

Have you checked to make sure the flywheel key is not sheared? If sheared it throws off the timing and will backfire when you try and start it. Somewhat common on those engines. If you have the engine model number I could look up a parts diagram to better answer the carb question.

I believe the carburetor part number for your model is 632631. I have the same TroyBilt chipper/Vac. It has a Tecumseh H50-65582W engine. A good parts diagram can be found at

If this is the right part, you can buy it at Jacks Small Engine parts for $79
Good Luck!

You may have better luck in identifying the engine type and manufacture (Briggs & Stratton, Tecumseh, etc) and get the number of the engine vs the machine itself, if possible. If you are able to do this, you can search ebay or the net for a wider range of possibilities for a purchase.

If it has a float type carb, open it 1.5 turns. If it has a diaphram open it one turn. If it has a Walbro carb, there is no adjustment. Once you get the engine started you may adjust the carb to fine tune. Open until it begins to lose RPM's then close until it starts to lose RPM's. Return to a point between the two. Good luck...Lee

The float needle in the carb isn't shutting off the fuel and it's pouring out the vent. This is a common problem. You should tear the carb down and replace the needle and seat. You should check the float to make sure it doesn't have fuel in it (if you shake it and hear fluid inside it, it's shot and you'll need a new one.) Parts for Tecumseh engines are readily available from most decent lawn mower shops. Be sure to take you model numbers from the engine to the dealer to get the right parts.
