220 NHH Glow Plug in intake?

That could be, I rather doubt it. I dont ever recall a 220 having one...its been a while though. I would expect a compression release to be found for sure.

Cummins.... NHH Glow Plug

Yep, the Crown Cummins did use a single glow plug. Cummins have always been a bit fussy starting at cold temps. The wiring is missing from your bus and almost all others. Usually there is a transformer located near the small electrical panel near the engine under the drivers window. That panel usually has a switch labeled glow plug. The sequence is at drivers seat, engine ignition on, outside to side compartment, hold glow plug switch for a 10 or so count, then push start switch while holding/opening throttle. This start method was marginally effective. When the temps plunge here in Idaho, I use that glow plug port to squirt in some start fluid as engine is turning. Starts great even at -22 degrees. My remote start switch is wired to spin engine merely by pushing the outside button.
At the same panel, there is also a small pump for adding fuel when a start is attempted. Starting fluid or a gas laden rag does a better start job. Frank

Starting fluid is fine...IF you know how to use it properly. Of course, not with a glow plug or manifold heater.

Not from where I am sitting.

my crown has most of this still-- there is a pump plunger ,a push button and a big red light ... as I understand it - you push the button, the light glows, after a time you pump the 'handle in and out to spray fuel onto the white hot glowplug coil, it burns and heats the intake manifold and air . basicly , you start a fire in the intake ........ crank while doing all the above .... motor may start ... got this from some oldtimers at the historic truck site .. and like I said all this stuff is still on mine .. looking in the parts books reveals that on most 743 cummins engines the comp ratio is down around 13-15 to 1 ... not high by today's diesel specs ..

Note: Liquid Wrench is a whole lot easier on the rings than ether. Since WD40 was reformulated a few years ago, it doesn't work well as starting fluid anymore.

when starting mine up from dead cold, I do it the way my dad did it on the 190 in our hay truck : hold the compression release lever down, start button, spin the engine until it starts to spin up- you can hear it speed up slightly, then drop the compression lever---- brumm-- running .. Once it's warm - then I just hit the start button inside , hardly cranks , and it's off... I use 3 grp 31 batts in parallel, got rid of the 2 giant 8d's it came with..

What does Liquid Wrench do to the air filter element?

Rich

you spray the starting fluid, etc after the air filter.. or in manifold port..

Interesting aside on all of this hard starting talk...

My buddy, Stretch, has an M35 deuce and a half military truck with a multi-fuel engine. He is running straight used motor oil as fuel, which makes the truck naturally harder starting. Once, when it was cold out and he had misplaced his starting fluid, he had me plug the end of the exhaust stack (while he cranked) to force the compression, hence heat, to build up. Never would have guessed something like that would work, but it did.

I have multiple ways of helping a diesel start. But, the ones I have are 22-1 compression, and start at 10 degrees without any help, if you are running diesel fuel in them.

That being said, I run straight motor oil as fuel. (M35 military truck with multifuel engine)It's a lot harder to start. It will start above 70 degrees or so. Used gasoline in a spray bottle to help, ether, or plugged the exhaust.

Truck comes with a spark plug and a sprayer, you push a button while starting, and it makes a flame in the intake to help it start. I have no idea how well it works, due to running oil in the tank. On diesel it probably works fine.

I bought a ether start kit to install, haven't done it yet. You pull a cable or push a button, and it gives the engine a measured shot of ether to start. Uses a bottle that looks like a propane bottle. Supposedly you get 200 starts out of a bottle. Google quickstart.
