1994 Wellcraft Nova Spyder with 4.3l volvol Penta. This is building on a previous post about bogging down.
Motor starts and run perfectly every time. Will run up to about 2,800 rpm perfectly. For both of the above it has to be throttled up slowly for there to be no issues.
If you hit the throttle for a hole shot the engine boggs down and will either die or just slow to an idle.
If it does die it will restart with one turn of the key.
Getting past 3,000 rpm and on plane is random. If I can get it to 2,900rpm and just let it cruise for a few minutes it will slowly gain RPM and run upto 4,200rpm and cruise for as long as I want running perfectly as long as I don't back off the throttle.
Getting it to pass 3,000rpm is hit and miss.
Carb has been rebuilt, fuel filter at carb and water separator have been changed. Has fresh fuel, distributor and wires have been inspected and appear to be good but not replaced.
Anyone have an idea of what's next to look at.
