Jim in reply to your post #47400, it seems you are not the only smelly closet two stroker cat on this thread. We've all seen a cat sprint across the road only to change it's mind and try to go back = one flat hairy pancake at the roadkill restaurant, would you like a large fries and coke with that?? 
. It would be good to see a vid of an old open rocker fa30 running.
ps woke up at 2am this morning in a sweat, what a nightmare buddy, i dreamt my fox terrier saito was digging a hole in the back yard for the next door neighbours cat and unearthed two long buried fa125's.
pps capt nice pic of the fa120 fathead, huge barrel/head eh?

Hey Lonnie, I just thought of this, why don't you take that blower off that YS and try 2 things, no, not what you'r thinking>
1) run the YS without the blower and see if it's as powerful as a Saito of the same size.
2) put that blower on a Saito, then you may have some thing

More punishment (fun) for me, my newly acquired low time FG21 runs like $#@! beween 5k and 7K. Idles fine and peak is fine although the hsn is a little quirky. Doesn't seem to meter fuel evenly.
Checked the tank and lines, nope. Swapped the ignition, nope. Swapped the plug, nope. Swapped the battery, nope. It's sound mechanically. Hmmmm, carb? Checked it and all passages clear, diaphrams aren't torn. Hmmmm, more fun.
My other one runs perfect so I guess a carb swap is next.

No carb swap necessary, runs perfect now. Had debris plugging the end of the spraybar. Why would that only really affect the engine between 5K and 7K? Don't ask me, I'm not a flipp'n fluid dymanics engineer.
Bearings for the 120 Fathead should be here tomorrow or Monday. Now that's an engine I really look foward to running!

In that photo the author is showing the importance of ensuring that the rotary valve is indexed to the crankshaft properly, that's important as well.
Dave Shadel at YS got kind of peeved at me for disassembling my 91ac back plate assembly and explained how to reset the friction (drag) between the rotary valve and backplate while tightening the set screws that retain the brass pin. It must be done with the parts cleaned and dry and only a tiny amount of friction (drag) should be felt when rotating the rotary valve by hand.
Too much drag will load down the engine, too little drag will allow for leakage out of the inlet side of the carb during the two supercharging strokes which will cause loss of boost pressure.
Saito, saito SAITO!

In some situations, new won't do.
I am currently offering my very last. assembled engine. A Saito Fathead 120.
The remaining Saito, saito, saito engines that do go will be torn down and sold as parts kits, as- is.
YS of course , hanging on to those gems.

If it doesn't sell on RCG by noon tomorrow, I will make a video of what it looks like after squishing under 100 tons!
Tee her hee!
Doomed Fathead ???
