Re: odd fire 225 timing problem - or maybe not
A bad harmonic balancer is not really that common. The few bad ones I've seen over the years on any vehicle usually results in almost if not total separating of the outer hub from the inner. It is worth taking the time to check it though. Two other possibilities are that it's not the original harmonic or not the original font cover. Later odd and even fire 231 parts interchange on the 225. I'd pull #1 plug, bring it up on compression stroke and see where the timing mark lines up in relation to the indicator on the cover and where the rotor lines up to the cap.
