Fired her off, finally. New fuel pump (old made good pressure, but no suction), rebuilt alternator (you could watch the volts drop on a fully charged battery from 13.5 to 11 in 3 minutes, and the alt short load was so high it would not turn the motor over). The cam is not tolerant of a boat type idle speed. If you idle it below 850, it will do it, but dies after any opening of the throttle. Now at 13*btdc for idle advance (36* at 3600), and 3 full turns out on the idle mixture screws, but man, does it jump to 4000 quick when you snap the throttle open. Very interesting idle, too. Much more radical than I expected for a 286 cam with a ground in advance. This is goind to interesting when we get it in the water. I think we are pulling about 300hp if I did the math right. Looking for 60mph at 4600rpms with a 21 pitch prop. Spent today doing the last tweaking on the timing and idle mixture, and reinstalled all the teak wood that we had sanded out and reoiled (took 4 coats before it quit soaking up the teak oil like a drunk with a new bottle of Mad Dog 2020), and did some vinyl cleaning.
