Jim, the effects that lowering the cylinder has on valve train geometry can be measured and profiled. Maybe I'll do a before and after profile for valve lift if I'm feeling energetic but I don't think I'll see a difference in geometry if I don't cut the pushrods. If I end up running out of adjustment and have to cut the pushrods I think I will see a change because the pushrod angle will change.

yes of course, I guess I should have said, if you do both mods at the same time you will not see the difference between the outcomes of each mod..

you know after you guys started talking about increasing compression I had that thought about my 100, but she is all together, and the 125 carb will help fill the C-chamber anyways

For those thread members deeply concerned about 'the pope' aka el popo/chapo here's a recent selfie he posted while in rehab.
Dave a quick question...are saito pushrods only heat treated on the tips cause i was kinda thinkin about cutting one in half and re welding it just for fun.Would this make the pushrod shorter? but my big worry is will the welding process affect the hardened tips of my rods??

Pete, that I do not know, I suspect they are, the big block push rods appear to have hardened inserts in the ends and are hollow, the small block push rods may be solid. I may cut a small one in two and peak. I don't think I have any extra large block push rods. Placing the push rod in a small steel vice may bleed enough heat away to be safe.

Great guy, the pope. One of the BEST! Too bad he doesn't drop in here often.
I have a few spare pushrods lurking about . Need to take one apart and do the shortening operation. Does not appear that it will be difficult.
Jim,
The fellow in your video and I have worked at a couple of the very same places

Looking at the small block one-piece steel pushrods I don't see any evidence that would indicate that only the tips are hardened eg flame marks or color change.
Anybody have a set of Rockwell tester files?

Even high speed steel drill bits "cut like butter" with a diamond grit wheel
Geekster, those tips may have been polished after perhaps induction hardening and may show no color change. Even a drop of nitric acid may show a border between normal and hardened areas.. Wouldn't take much to make a small block Saito pushrod to just about any length desired.
Will have a look at the big block rods tonight.

The last 2 weeks have been absolute hell but I’m finallly back. My mother had a heart attack while on vacation in the Dominican Republic and I had to go there to basically rescue her. Her insurance was not accepted there and the hospitals wanted cash or credit with some signed statement up front before services begin. Fortunately, through my work (I fly a corporate jet) I had a local contact on the island who paid everything up front and saw to it that all charges were legit. We finally arranged for an air ambulance to get her into a hospital in Miami (another week) and she finally made it home 2 days ago. Here’s the big lesson: when traveling outside the country “get primary travel insurance”. Even if you’re young and healthy you can still get in an accident. For a few hundred dollars more it can save you thousands.
So yesterday, to get my mind off of things I ran my Saito 65. I used 15% Omega fuel instead of 15% Cool Power and it ran much better. Bad fuel??? I richened up the low speed needle a bit and it runs like a champ. It’s now ready for my profile Kat

Wow, near nightmare scenario. Hopefully a full recovery. Thanks for the heads up on travel coverage, now if we can only be assured the coverage is always accepted!
Getting a Saito up and running is great therapy too. Does "E-Power" supply props for liquid fueled IC engines, or is that an electric intent prop?
The Omega fuel would be my choice over Cool Power in any case.
Best wishes, Gary

my friend Jack, built thousands of oval arcing engines here in Vt, he built a Winston Cup engine for some guy (sorry that was 20 years ago, can't remember names), well Jack took the engine to be dyno'ed and it produced 18 HP more than another Winston Cup engine that was their the same day, months after the race Henderson Motorsports offered Jack a job, offered him good money, it was all in the newspaper, Jack turned down the job to stay in Vt.. poor Jack, life threw him a curve ball, after 30 years of helping people and not having his own car he started collecting parts to build a Hot Rod, he had the car, and as he was building the engine he got sick, he built the engine, a blown 700 HP Chevy 350, soon after he died, I was so upset for him, it was not fair

I know exactly what you are saying too!One thing for sure, the older I get, the less upset I am about making a mistake. Amazing how much a mistake can teach you...
....if you are old enough to listen...

The important thing is my mom is fine now but this was potentially bankrupting. My local contact pulled some strings to get the lowest possible costs. Medicare pays for nothing outside the US. Luckily, after 1 1/2 hrs on the phone her supplemental ins. covered the cost of air ambulance to the US.
Primary travel ins. covers everything up front and secondary reimburses. So unless you have deep pockets primary is what you want.

Quikturn, I am happy to hear your mom is back home and getting better, there is nothing like being home when you are sick !
Gary, when I was 15 a kid I went to school with stole a dirt bike, he told me about it, well the police found out he told me,,, oops,,, my father had a call, my father told me I had to go to court for accessory, I asked what's "accessory" I didn't even know I broke a law,, 2 things happen, but just remember 2 wrongs do not make a right.
a) never arrested, my right were not given to me, I didn't know my rights, and I did not have a lawyer, but I went to court and I was found guilty of accessory
B) I got the same punishment as the kid that stole the dirt bike, 6 months probation, haahaa the kid got off probation 2 weeks before I did, go figure,
the moral of the story, 3 wrongs do not make a right ether !!
boy I tell you, "ignorance of law" sure learned me some things,, in all the time since I was 15 I have never had another run-in with the law, but that kid has a police file 5 inches thick
my poor brother, he stole a car once, I was 14, he never came home again, he was 17, yes I have learned

Welp that was exciting I know he said it but with this Missouri blood I have, I had to see it for my self.
The 180HC doesn’t like glow plugs WOW!!!
Manage to get it to run 18-6 wide APC turned 8800 rpm’s, cool but it doesn’t idol so CH ignition time.
How ever the 150S GK ran great if I had a servo hooked up for throttle I could probably do better at the idle but at least I got som number’s and I can send it down to be put in a L4.

So I was able to find some time early this morning to cc the pig. Took 3 readings for all measurements and averaged. Largest deviation in volumetric measurements was .15 cc.
Combustion Chamber: 1.80 cc
Glow Plug (Type F): .030 cc
Mechanical Swept Vol: 13.97 cc
Effective Swept Vol: 11.4 cc (58° ABDC)
Mechanical Compression: 8.634:1
Effective Compression: 7.229:1
More later,
Lonnie
