The necked-down part of the rod is polished as if it was turned on the finest lathe.(see picture above) It is amazing to me that it could polish/turn so evenly.

Thank you, Walt

I will do that. That is very generous of you to offer.

I am still working on this.

Need a little help. Parts are here...found valve cap missing...thanks to reminder note in tinkerer200 (Walt) instructions.

One rod is aluminum and one is steel.

I believe these were/are in the wrong position in the head.
The aluminum rod was on the top.
When I cranked it before finding the problem it backfired OUT THE CARB...
Doesn't that indicate the intake valve was moving? Yet, the aluminum rod was collapsed and off it's rocker.

were the rods in the wrong place?
That is my question....thanks


I am now waiting a valve cap I ordered....no one has one in town.....next week to fix it.

Steel rod goes to the exhaust, alloy rod goes to the intake.
I pull the steel rods out of blown engines to replace the alloy ones.
Never though to turn them around, so thanks Walt I will do that in future.

Installed, adjusted valves as instructed by tinkerer200 and started up fine and mowed.

Success!
