Hi, I have an 82 Renken with the Chevy 229 v6. It has points(which are probably the source of all my problems) and a rochester 2 bbl carb. Here is what has been happening. The first time out on the boat, I ran it for around an hour to an hour and a half. Then, it started losing power. It slowed itself down, and the motor sounded bogged down. Then it started pinging and backfired, which cut it off. The temp had risen too. I had to crank it back up because I was in traffic and at idle, the temp went right back down. When I gave it gas, it just sounded bad, but didnt actually accelerate. It seemed like a fuel delivery problem. I changed the fuel water separater(twice now) and rebuilt the carb. Took it out twice since then and the same thing keeps happening, but quicker each time. It only took 45 minutes, then not even 20 the last time. I changed the coil this weekend and it sounds better, but I have to get it on the water to get it to do it. It will run when it is doing this, but not hard. It will not go on plane although the temps dont seem to rise as much, but that may be because I am not holding the throttle open since something is clearly wrong. I set the points to .18 and the timing to 10 degrees, like it says in the book. It was at 8 degrees, but that would make it knock more, not less, now that I have set it to factory spec. I used a marine carb rebuild kit and set the float. The other odd thing is that at idle, in the yard, you can hear an occasional miss and giving it gas, sometimes it will just stumble and miss real bad, but other times it just revs up like it should. I was thinking of changing the fuel pump, would and automotive style be acceptable? Also, before I bought it, the man had his mechanic put the points in and they are from the car parts bin. Could that be part of the problem? It was doing this with the previous owner too, but he thought changing the points, wires, cap and rotor had solved the problem.
