" jls" wrote in message ... Cessna 150's came from the factory with 100 HP Continental O-200's. Majoring the engine costs 5 to 10 thousand, sometimes more. How does one overhaul an O-200 for "5 to 10 thousand"? Five thousand would be beyond believable. Ten thousand would be cheaper than any price I've seen. |

" jls" wrote in message .. . You are so right. I like those little Lycomings with their 2k hour tbo's and solid lifters. They last forever but are expensive to overhaul. If OH'd with the proper parts, the Lyc O235 is good for 2400 hours TBO. J Severyn |

It was flown regularly. |

A poor choice, but one often made for a for-sale aircraft..... "A real cherry," 10 hrs TSMO..... Chapter Two is a log book notation of 110 hrs TSMO, 10 hrs since top overhaul..... |

IMHO, overhauled Continental O-200 cylinders don't last, although that's probably not what happened here. If you overhaul Continental cylinders they should have bushings installed in the rocker shaft bosses, they should have new seats and certainly new guides. And probably new springs. Most A&P's knowledgeable about them will tell you they will last 500 hours max. In the meantime, worry about cracks, problems in the rocker box, and on and on. For the money Milleniums are the way to go. Unlike Continentals, the Superior exhaust guides, a big problem with all the small Continentals, are surrounded by the aluminum castings in the heads for better dissipation of heat. And you're not stuck with the AD requiring you to retard the ignition timing from 28 to 24 deg. btdc, and losing horsepower. While Continental cylinders have no choke, Milleniums do --- .002" taper to account for heat expansion near the top of the cylinder. Then Millenium valves and guides are set up to take the punishment which causes Continental valves and guides to wear unevenly, get hot, foul with carbon, and stick. Milleniums come from the factory with rockershaft bushings installed, while new Continental bosses are aluminum which quickly wear and get sloppy. I could go on and on, although certainly not an authority. If you want to know more read up at Sacramento Sky Ranch's website, read the literature on Millenium cylinders, or just do some googling on O-200 cylinders, which by the way are the same for C-75's, C-85's, and O-300's, except for a few variations with springs, valves, and guides. We just installed some new Milleniums at around $850 per unit. They came in big tall foam-filled boxes with pistons, rings, rockershafts, piston pins, gaskets, yep, just about everything you need for a top except the tools, rocker arms, and elbow grease. Noted with great curiosity were the blue inscriptions on the valves and pistons --- the words "Italy" and "Brazil" respectively. Do you suppose these parts were bound to those countries and got sidetracked? |
