321 in my 444 misfires @ higher RPM idles fine. Eng has 3hrs on new piston, rings & valves. Just installed new points, coil, condenser with no improvement.(changed cond twice) and bypassed ign switch to coil. Am sure(?) is a spark issue as timing light intermittently flashes when eng sputters. Points @ .020, plug @ .035. HELP PLEASE! thanks, john

dawg I have a 444 with a Kohler 321 also. I had a similar issue and come to find out under my points was a little oil. I disassembled it and cleaned the surface with lacquer thinner and reassembled and adjusted the points and issue disappeared. I'm not saying this is your problem and it amazed me that this was my problem but it did disappear after cleaning.

Keep the Peace

Check where the wire connects to the points. I've seen that connection short out to the points cover.

Did you clean the points contacts with electrical parts cleaner? New points can have a film from manufacturing or oxidization from sitting in the packaging.

Is the replacement coil internally resisted? I have seen the wrong coil coil installed in the past.

Just throwing out free things to check.
