A carburetor takes at least one crank to begin to draw correctly. I didn't even know you could get rebuild parts.... I've put one set of bearings in it. And carburetor membranes. Other than that, haven't needed any. |

Not too many people would change that. mike |

Not too many people would change that. No, actually, I meant 'crank' as in crank. There is no starter rope on this model. You turn it over with a fold out crank handle on the top of the engine...where the traditional recoil starter would be. As for changing out a crank...I've done it. Not on this model, obviously, but I did service lawnmowers for a number of years. The most common failure on Tecumseh engines I saw was spun bearings and cracked crankshafts. One of my experiments a number of years ago, was on a Murray I picked up at a garage sale. It had a Tecumseh motor on it and it needed a tune up and a carb kit. Took about an hour and a half to rebuild the carb and I had it running. While doing the tune-up, I got the bright idea to improve performance by as much as I could get away with. Fitting new rings, balancing the crank/rod/piston assembly, shaving the head, hand lapping the valves, porting and polishing, and rejetting the carb, I got it to nearly double it's full run rpm's, but it required premium fuel. On a smooth payment, it would dance around the output shaft by itself. And the output chute could drive a wind tunnel. It was the only lawn mower that needed a tail rotor. I had to advance the timing by a bit to get it to run smoothly, and put a bigger squirrel cage fan on it to keep it cool. And I put a port fin on the exhaust header, but it started strong, and ran like a monster. Until the casting let go. I was picking aluminum out of the siding on the garage for months. Hot oil flew 50 feet in every direction. And I never did find the spark plug. But, damn, for those two hours, it was something. Never tried to punch up a Briggs, though. |

I once thought of trying to make a hovercraft using a lawnmower as a base. Being a kid, I figured just bending the blade a bit more would be enough. It's just as well that I never tried it, I would have wound up missing toes. Or something. mike |

Or something. mike After the first season of Fireball XL5, I tried to build a jetmobile using two riding lawnmower engines and counter-rotating ducted fans. I got it to lift, but it was too unstable to remain off the ground. I needed to build a counter rotating gyro, but never got the transmission down to a size that was small enough to fit inside the bodywork. |
