"Hello, some advice please. I have recently purchased a boat with a 2.3 liter Ford OMC stern drive (don't laugh to hard the price was right). I have done some work and it is running pretty good but from about 3/4 throttle to full throttle it pops and miss fires a bit, when I back off a little it smooths out and runs good. I have put a new rebuilt carburetor on the motor as the old one was in such bad shape (big improvement). I have put new points,spark plugs,rotor and dis. cap on it. Pretty sure I have the point gap right but my dwell meter craped out and I can't buy one locally anymore. Set the timing. I have done just about every thing you would do with an engine tune-up. One funny thing I have noticed though my dash tachometer seems to read the right RPM at idle and up to maybe haft throttle, then it goes off the scale at 3/4 throttle, whats with that?
I have being reading a couple of posted threads here and am thinking I may want to upgrade to an electronic ignition system from Petronix to improve my engines performance, hoping not to have the problems sum others have had. Ignitor 1 or Ignitor 2, flame thrower coil 2, hmmm. What are your thoughts on this gentlemen. Should I get it running good through to full throttle before trying the ignition change?"
