I have a Coleman Powermate model MZ300 and the pull cord snapped up by the handle. I removed the casing and retied the rope but everytime I go to install the casing the rope comes unraveled. Not sure what I am doing wrong...it seems like this should be easy...any help out there is appreciated.

This requires a bit of strength in the hands and the recoil will have a fair amount of tension behind it. Best have a small engine service center look at. Not expensive

SOURCE: want to remove the starter recoil from my powermate generator

I got one of these pieces of junk, and had same problem you described.

You will need to remove the end panel to get to the blower housing. You will have to thread the rope through the handle until you have enough slack to remove the rope from the handle. The end panel should now be free to remove entirely.

Find the 3 bolts that hold the blower housing on, and remove them. Once you get it off, make sure that the rope has a knot in it so it won't get retracted into the pulley recoil assembly. Take a screwdriver and push the rope back down into the pulley (that was my problem). Assembly is opposite of taking apart.

SOURCE: Want to add electric start

To determine if an electric starter can be installed, begin with the model number and type of engine. The engine model number (not generator number) will clue you in on the availability of accessories. In order for a starter to work on your engine, there needs to be mounting holes drilled and taped onto the back of the block to mount the starter. Also necessary is a ring gear on the flywheel and a knock-out plate on the fan cover to allow the nose of the starter into the cover. For reference, find a dealer near you that has the same type of engine with a starter already installed so that you can see the differences. Good luck of upgrading.
