Axiom Home Page Forums General Discussion The Water Cooler What funny thing are you appreciating tonight?

Just an FYI, dieseling is due to the RPM being to high and the engine keeps sucking in fuel at idle keeping the motor running. Make sure after checking the timing to set the idle speed to spec. With the plug wire back on the engine now obviously runs better and has more RPM at idle. It really isn't a matter of the timing being off as long as the idle speed is correct. You can run the timing 10deg advanced if you want as long as the idle speed is where it is supposed and no other carb issues it won't run on.

Really no need to increase the plug gap, as well unless he has further modified the engine. It's the increase in plug gap that causes the increase in the KV output. The extra plug gap, just changes the flame front and in turn chnges the burn rate in the cylinder, causing some other issues.
