Bad idea Bill. The pressure put on the cam gear teeth using this method can ruin them. Better to use a c-clamp on the side of the cam gear while torqueing the nut. This puts no strain on the gear teeth. Mike

The old engine sounds like most old Model A engines without the annoying Knock-Knock it had before.

Thanks to all your suggestions it looks like we may have solved this problem. Now all I have to do is figure out where I have an exhaust leak.

Thanks again.

Well guys, likes I wrote to soon! The "knock" is still there.

To further report on this "knock" I did take the side cover off the timing gear to check it based on some of the comments. I did find the timing gear is great shape all the way around. Also no play with it's shaft going back and forth.

So at this point, I think I will just see how things develop and go from here until something else turns up. Thanks again for the comments.

Was it knocking before the timing gear was replaced? If not, you may want to check your work. It is pretty easy to remove the front cover compared to getting into other areas of the engine. If you check under the cover, don't overlook the plunger assembly. The spring may have broken, or it may be so full of gunk that it cannot move freely.

The timing gear was replaced about two years ago. Had no problem up until about a couple of months ago.

The problem may still be values that need to be adjusted. But for now I think I will let it go and see what develops. It may be just the "Model A" sound.
