I’m after a bit of help…
Some history, I had a VP 260 (AQ151 with 290 SP-A leg) in a 16 ft speed boat. Took this engine and installed it into a 23 ft cabin cruiser (Invader 2200).
I serviced / overhauled the engine, new head gasket; seals etc… spark plugs and leads, coil, alternator, etc, cleaned and rebuilt the crabs (twin solex) I replaced the timing belt, checked and rechecked the timing several times (all the notices line up as per the VP workshop manuals and Solec manual), she idles fine but under load I can’t get anymore than 1500 to 2000 rpm. If I rev her out of gear she revs fine, any ideas?
Could my timing be out by a couple of tooth on the top pulley, and she is just off when the valves open?
Fuel starvation / carbs issue?
Wrong prop ?
Any help will be much appreciated as I’m going round in circles!
Cheers
Stu
