I had problems with this recoil. The Ardisam site no longer had any parts for this vintage. The Tecumseh motor is a TC300. There are parts and diagrams available online. That plastic “dog” wore out after 2 years on ours. It would “skip” for 2 or 3 pulls and then would catch once. We had used it for an additional 7 years with it working like this, but I never completely trusted the auger because of it.
Last night I replaced the recoil with the updated one from Tecumseh. This has 2 metal “dogs” that drive on the cast flywheel and a new pulley core. The flywheel is not threaded from the factory. The bolts are 6mm 1.0 threads. The aluminum flywheel tapped easily. The other modification that was required was cutting the metal cap that sits below the recoil pulley. I cut this down with and aviation snips so that it did not block the dogs from engagement. The metal piece would bind the pulley so I shimmed the metal cap with a 1/4″ lock washer. The pulley could be champhered prior to instillation and this would not be necessary. I would recommend not taking out the recoil spring. If the spring looks good and stays in the housing then use it.
The new recoil has a good sturdy feel and works very well with no “Skipping” like the plastic “dog”.
