I have replied to many threads over the years, sceptical of claims of starting in warm weather without glow plugs. I have owned so many of these and even the ones that started good in cold weather still needed some plugs when it was hot out with a cold engine.
Well, I now have one that starts without plugs pretty easily above 70 degrees.
So there.....I was wrong.

I am an electronic engineer. On good days I built spacecraft, now I just redesign old cars.

Theory is great and necessary. But until you "smoke check", you cannot prove your idea.

Not very good for your motor. Gonna take more time to run right. Why not just fix stuff it’s so cheap and easy to re do the whole glow plug system.

I did it to drop compression, so dont have to worry about the boost those twin underside hx35s put out on a unmolested pump. I dont drive it till it gets to a certain temp idling, then drives the same every time. With the old starter if I tryed to use it, it would kill down the batteries too the point of needing a jump. The new stater dose a lot better and may chance it, but need to get replacement tiny nuts for the solenoids. I could charge the batteries if could get this gen set to start, but tried to remove a screw that should not had and now is broken.

Really....
The conditions I was speaking of, the engine started very quickly, like I had used plugs to start it. No smoke or roughness.
And, it needs a whole lot more than the plugs wired up, it needs a truck hooked up to it since it is sitting in the dirt with a radiator propped up in front of it

Interesting. I have a more cold blooded engine it seems. even on 100* days it will start way easier and smoother with the glow plugs. I could probably get it to light off without them even down in the 50s and 60s, but she sure doesnt like it.

"Cosby sause" only on my truck! I gave up on glow plugs trying to fire WMO. It doesn't matter if it's 95° out, and with NW Florida humidity it's almost like water injection! Lol

Most that I have had, basically needed glow plugs used to start at any temp, without lots of short cranking cycles.
