I have an old West Bend engine, I believe it's a 580 or a 700, I can't find any markings that would tell me which it is, It is missing its fan shroud but is otherwise working, the only number I could find was #2703038 on the cast aluminium base pan where the fan shroud would go, I don't think this number though will identify the engine for me, where should I expect to find the number that will identify the engine?
Identifying West Bend Power Bee engines
I was looking to put a 700 on a bike of mine but was having trouble finding one. I called Power Products and talked to their outside sales rep. He couldn't help me but gave me a number to an old timer that build and raced them back in the day. This guy told me that even he could not tell the difference between a 580 and 700 without taking it apart to see what was inside.
Kenny1- Try contacting Frank at Poohruth@aol.com. I found him on ebay and he is A+ rated. He is custom building me a rare early 60's NOS WB700 modified with a big tilo carb and yes there are engine mounts and 9/16th clutches still available. He has collecting Wb's for over twenty years and he is great to work with. I am expecting my vintage 700 to be a real screamer. I know he has a real nice 580 hardly used in stock and a 820 which is just too crazy to put on any MB. I will post pix when its comes - mid December. Nothing is more fun than a vintage 2 cycle engine on a MB. Bill1
The round barrel 580 WB engines have a cast iron/steel sleeve, whereas the 510/645/700 round barrel engines are chrome bore.An easy way to tell is remove the exhaust and look thru the ports at the back cylinder wall...with a flashlite.Crosshatch on a cast iron,reflection from the lite on a chrome bore.(The 610/820 square barrel models are the same way..........610's have a cast iron/steel liner,whereas the 820's have chrome bore).
Downside of chrome bore is it can flake,no oversizing,and expensive to re-chrome.Upside is it's tough as hell,and lasts a long time if it doesn't sieze/overheat.

Elheffe, 2 inch bore, 1-19/32 inch stroke, chrome bore, 5 cubic inches. They came in two configurations, loop scavenged and cross scavenged (model 50052 and 50054). If the carburetor is on the bottom of the crankcase it is loop scavenged, carburetor mounted on the cylinder it is cross scavenged. They were rated at 4.25 HP. They were not made for to many years. They were used in the rookie class (karts) but were not too successful. and industrial applications, (chain saws, generators etc.)
They have an aluminum rod with needle bearings on the crank pin and wrist pin, the mains use ball bearings. The crankcase is magnesium, the cylinder is aluminum with an integral cylinder head.
