--Here's the thing: I've been thinking of getting one of those silly gasoline powered blenders. Trouble is, they've all got one of those pull-cords to start the little engine (the tend to be cantankerous too..). Well, since trying to start a crummy genny a while back I'm now nursing a torn rotator cuff so pull-starters are a no-no. Has anyone seen plans for a kick-starter floating around? I'm guessing there's gearing inside to accelerate a footpedal output to a rotation rate needed to start a small engine; i.e. it's not a 1-to-1 gearing..
The old maytags used a sector gear on the pedal to drive a pinion on the crank. At a guess, something like 3 or 4 inches of throw to get maybe 2 turns of the motor. Maybe you could chop up an automotive ring gear and weld a section onto an appropriate pedal and add an adapter to the motor to take the drive gear from the matching starter. Your pick on how you want to do the ratchet. Alternatively, maybe a socket adapter and a cordless drill...? --Glenn Lyford
We had some old Briggs and Stratton motors when we were kids that used a piece of roller chain to engage a small ratcheting sprocket on the crankshaft's outer end. The kicker had a spring return, so the chain was well out of the way when inactive. If there's any interest in such an idea, I could go into more detail off list. Some of the basic parts are on sale on ebay right now, see:

I googled "briggs and stratton kick start" and got about 5000 hits.
Go to this site to see the one I'm talking about and two or three other designs, too:

You reminded me of a joke here, Chris. ;)
--snip-- Those Clever Americans!
The FAA has a device for testing the strength of windshields on airplanes. They point this thing at the windshield of the aircraft and shoot a dead chicken at about the speed the air- craft normally flies at it. If the windshield doesn't break, it's likely to survive a real collision with a bird during flight.
The British had recently built a new locomotive that could pull a train faster than any before it. They were not sure that its windshield was strong enough so they borrowed the testing device from the FAA, reset it to approximate the maximum speed of the locomotive, loaded in the dead chicken, and fired. The bird went through the windshield, broke the engineer's chair, and made a major dent in the back wall of the engine cab.
They were quite surprised with this result, so they asked the FAA to check the test to see if everything was done correctly. The FAA checked everything and suggested that they might want to repeat the test using a thawed chicken.
--- Chaos, panic, and disorder--my work here is done.
There are many variations on that joke. I went to a lecture once by a guy who did some of this work originally, and he had footage of just about every kind of bird being fired into an engine. Kind of gory actually!
