Just drill a hole in the head Eugen. Install a spark plug. Run gasoline to it. Have a monetary switch in the cab. So you can fire the cylinder, when needed. Problem solved.
Aren’t I some helpful, hmmmm.

Great idea Noel!!! This means you tell me I should do a compression test first right?

Yessir! I wouldn't want to do all that work to put a spark plug in and not have enough compression right?
Oh, but look what the cat dragged in!

Nice kit. Heavens no, I don’t want to put you through all that work first before you do the test Eugen.
If you need any more helpful ideas, just let me know.

@Eugen that kit makes me want to add another tool to my box. Then I will kind of remember there was one, but did it get loaned out, or which box is it in, or did it ever exist.
I did that with an industrial Hobart welder yesterday. I remembered it as a 600 volt 3 phase. Looked on the net for a 208 v, single phase, then took a stroll though the yard and untarped said unit. It would have been used a couple of times this winter if only....
Too many tools in the toy box.

@Propane57 keep the ideas and rambling coming!

It's all welcome!
@Spike188 no need to buy this kit, you can always borrow mine if we meet in Toronto. Mind you, after this backhoe is gone I probably won't need it, but it fill a clear purpose right now. I'll see if I can do the test this evening after work, and then I'll know for sure there's a gremlin in the engine.

Of course. Not renting Dave, you can just use it.

@Eugen I was just kidding out needing a test kit. @DavidBarkey has more need for it than me.

Cylinder 1, zero compression.
Burnt valve?

valve, hole in piston, or head gasket. I would rig up airline to cylinder with piston at bottom of stroke. That would have both valves closed. If air discharges from oil fill port it is a piston issue, if from exhaust then exhaust valve, if from intake then intake valve, if rad water bubbles head gasket.
Also check the compression on the other three for a benchmark before tearing down. It would give you an indication of how far into the engine you want to go. This may be a sleeved engine so doing a single hole might be an option.

Zero compression. Jumpins that’s not good. Valve would have to be wide open and burnt I’d say. Just guessing. But there’s a big problem some where. Hole in piston.
