Once again this morning the 88 760 Turbo did not want to start. Temperature about 20 degrees and the engine caught once then acted like it flooded. I turned it continually until it caught and finally fired on all four cylinders. There was not the first smoke to indicate a flooded condition though. I am thinking now that this is a combination of problems: worn cylinders, poor spark even under good circumstances, and the fact that with an expansion contraction coefficient about 12 times that of the steel cylinder, the already low compression (8.7:1) is further reduced by a piston that has shrunk several thousands of an inch more than the cylinder wall in the cold, multiplying the wear.(Which would explain why the Non-Turbo B230F motors with 9.8:1 Compression start in cold weather) I am going to do several things to try an help the problem short of putting a block heater in the lower radiator hose. First, I am putting in plugs that are two ranges hotter than the factory ones. That is a good bet for an older motor anyway. An Accel coil with a hot spark is definitely going in, and, if that doesn't work, my wife has given me permission to build one of my chevy motors for it. I'm thinking of a 4.3liter six mated up to the AW71. Anybody tried it?
