Is there anyone who manufactures 21cc Echo conversion parts? I am looking for prop hubs for EI, mounts, and mufflers. I have a good source for engines, but I don't have the tools needed to build the parts. I'm considering a converting pair, for a Nosen 310.

This isn't exactly what you are asking for, but here is a way to do them...

If the engines are from a leaf blower, they come with a nut/stud that you can use for a prop hub. Using a hole saw, cut the center out of the flywheel. (This only works if it is an aluminum; not laminated steel, flywheel.) You can then drill a hole in the center piece of the flywheel for a magnet. Make up a bracket to hold your sensor. I just use studs screwed into the back of the engine to mount it right to the firewall with flat washers and nuts. Gut the muffler and leave off the little bolt on exterior baffle. Bolt it all together and you are good to go. I have done several this way.

Otherwise, check with www.ch-ignitions.com to get your ignition, and see if they have a prop hub. www.wackerengines.com may also help, and they are others here in the forum that make mufflers and parts.
