2 Cycle Walbro Flywheel

Hello all and Cheese! I'm finally back in the shop half days after my 2nd back surgery. I am building a quarter scale car for fun...NOT racing. I have a really nice chainsaw engine but I haven't a clue what brand it was used in and I have never known how to determine the engine manufacturer? It has a Walbro Flywheel with G-57 which was in the casting! I can't find any stamped identification. This flywheel has a built in key that is sheared off therefore I need to replace it and I haven't a clue where to look on-line ? The only other destinquishing feature is the fact that it has NO pawls. I chose this engine because the pull cord is at one end of the shaft and the Flywheel is at the other end, perfect for my needs. I have another flywheel that matches this one but I can't get the engine to crank with it...Timing is off? WELL, where can I possibly find one of these ancient creatures? Thx, Ron (Sure hope all is well with you, cheese, as well as the family and businesses)

Since Walbro 'wheels were used on many brands it will be near impossible to determine the brand you have. That is unless you can submit a photo of it (the entire engine...at different angles). I likely would be able to ID it then.

An Answer & More Questions

Well, with all your help I have figured this one out...Finally! I was wrong it is NOT a chainsaw engine. This 30cc unit is out of a John Deere BH30 Blower. The Walbro G-57 Flywheel/Rotor has a sub P/N UP03856. NOW ANOTHER QUESTION OR TWO: They want $44 for this flywheel. Ubsurd! Where can I buy parts at a reasonable price??? Can a flywheel like this one be repaired? I have Flywheels running out of my ears. I have several that I can fit on this shaft - Can I get it to run with almost any flywheel as long as it fits onto the key properly and is the same size or will there always be a timing problem without the exact flywheel called for? Thanks again for everybody's help, Ron

The 44 fish sounds like a good deal...my suggested list price is $58. The key in relation to the magnets is what determines the timing and it better be on the money or you're going to fry the engine.

Many Thanks

Thanks for the info on the cost. I found a company that this item (NOT OEM) would cost me about $23 IF I Qualify and sign up as a dealer of their products?? I guess I may have to bite the bullet and do it. Anyway I really appreciate your insight and help! Thx, Ron

Hi Ron!

Glad to hear you're back at it! That blower is not very common, so finding a used flywheel may prove to be difficult unless you can find a different piece of equipment with the same one (which is definitely possible, but I don't know how you'd ever find out without visually checking dozens of engines). You might get lucky on ebay. I think I'd go for the new one. $44 isn't bad.

Sounds like a neat project (the car). Keep us posted on your progress!
