With retirement and a move from Houston to N. Colorado, I have not given my Sunbeam IV much attention for a good while. Now that I have some time to drive it, I am having starter problems. The starter cranks well, but the instant the engine fires, the starter disengages the flywheel and whirs to a stop rather than continuing to crank the engine until it starts. I have tried 20 0r 30 times in a row with the same result. Sometimes I get lucky and it starts, but usually not. Any ideas? I have a 1725 with a standard choke.
