Part needed for McCoy No. 2 .049 engine

I googled "recoil spring wen Mac" and along with this thread a few others show up. Here's a interesting one from 2008 where the guy disassembled the starter, bent the broken end back to shape and had a working starter.    http://www.modelengine.org/phpbb4/viewtopic.php?f=18&t=4636

The "rivet springs" and larger diameter Rotomatic starter springs are from carryover of Wen Mac parts inventory. Testors later decreased diameter of Rotomatic assembly and replaced rivets with a bend in the ends of the springs. The new version springs can be made to reload into older Wen Mac style starters and work fine. Sometimes a little snip/bend is needed where spring anchors to housing. Rebuilding/reloading Rotomatic starters takes practice and can cause you to advance several levels in cursing and swearing until you master it

Best cheap source of new version Rotomatic parts are from pipe bomb engines. And you can usually get a good glow head to boot. One caveat though: The crankshaft and clutch assembly splines are a little coarser on some or all?? of the Testors redesigned Rotomatic starters. Use magnifying glass when in doubt.

Thank you to those who have replied to my request for assistance to find a recoil start spring. My spring was found to be broken off where the spring end attaches to the center bushing that rotates around the snout of the engine when I disassembled the recoil starter. This spring steel is tough to drill and I had little success in putting another tiny hole into the existing spring in an attempt to rivet the parts back together which has started my search for a new one. I guess I'll just keep looking on Ebay until something less costly with a functioning spring starter comes up. I appreciate the input. prostreet.

There should be another hole opposite the broken rivet in the drive collar. If you don't find a replacement spring you MIGHT be able to put a small Z bend in old spring and make it work.

I don't think a z bend in the spring would work in the large hole opposite the original riveted location. There's very little clearance between the collar and the shaft that it turns around so I think that the piece of spring on the end of the z bend would cause binding and prevent the collar from turning. The original rivet was center punched inside the collar to expand the rivet end to prevent it from coming out. This kept its profile low which allowed the collar to turn freely once the spring was secured in place on the outside of the collar. I appreciate the suggestion though.

Is this what your looking for?





If yes, then I will strip it down to the case and starter and send it to you. Just PM me your address.

What do you want for the rest of the engine?

Probably not for sale Victor. I'm always looking for the spares for this type engine, needle etc. The spring starter is good, but the case is trash so if it can be of use to someone I'm willing to let it go.
