Maybe FastJeff can help me out there, I'm running a 76 440 W, but the engine model number is 400BWR is there such a thing as the 400, also have the same 2200 rpm problem, pulled the distributor, cleaned all. replaced advance springs, all is loose & free, new rotor, cap ect..., timed @ 10 deg BTDC @ 700 rpm, new spring kits says advance should be 18 deg @ 1200 rpm, and 26 deg @ 2600 rpm ( full advance ), well none of this worked, watched the timing mark while running the engine up to 3000 rpm, advance moved maybe 5 deg if lucky, is it time for a new distributor? Can I replace this one with a vacumn advance set up? or maybe a conversion, can't find any re-maunfactured, new or any thing for this boat, Dist # IDH-7003-36-4.
Any help appreciated.
Thanks, Abster
