Default Re: Engine Misfire Knock

Thanks for the update - glad you were able to figure out. In this case you may have been able to narrow things down quickly by 1st disconnecting the fan belt, would have ruled out the generator and water pump. Then use a stethoscope, or a very large screwdriver, or a broom handle to listen for the noise. Many are not fond of nurex wrench. Personally, it is not as accurate, but is handy to have on the road, if done correctly gets you close enough (have to remember in timing to set the spark lever at full retard).



Get the timing set correctly with the official method, and just for kicks use the wrench to check where the wrench is in relation to the #4 distributor lead post., I suspect that you will only be off by a very small amount, if any.
