While using my 642b yesterday it was very sluggish, then completely quit. When trying to restart, the engine turned over fine but would not start. I pulled the #1 plug and checked for spark, there was none. Checked coil for spark with same results. I am thinking of replacing coil, points, condenser, cap and resistor (ceramic is cracked). The problem is that I don't have a Bobcat dealer anywhere near me and I would like to get the parts from NAPA or some other auto store. I would like to match the Mitsubishi 4G32 engine to a car that they can look up. I have tried a few cars with no success. I have used this forum in the past with great results and think that somebody out there has a correct answer to what car matches parts. Thank you in advance.
