I think it is all the same 10,000 or 1 post there's no difference fwiw the same was for me I never saw that compression testing from HF it was always a cheaply automotive type but then I don't shop HF either

That Harbor Freight testing injector looks like one for a Cummins 855.  I'm not sure if you are getting a correct reading, and maybe damaging the copper in your Detroit head when you torque it down into the tube.  I have two Kent-Moore DD 2-stroke injector testers and the dummy injector has the same shape as the 2-stroke injector body.

Doesn't look like enough taper for a 855 Geoff it looks identical to the one A&E and NTX Tools sell for the 2 strokes probably not as good of quality the Chinese use a yard stick for measurement  fwiw both of the above are made in the USA and cost around 500 bucks for the set lol

You like scaring me Geoff?  I hope I didnt damage the head.

Bus is driving awesome...up the hills in the ozarks and into northern Oklahoma.  90degrees and pulling up big (not too long) hills in 3rd.  Temp holding at 185/190.

Seems to be running good...probably put about 800 miles on last two days.

Well were about 1800 miles down the road.  So far it hasnt acted up again.  I think i replaced a bad injector with a slightly better (but still broke) injector off the mecganics shelf.  Now qith a new (reman) injector from a shop im good.

Thanks all for the help and input.  Slowly making my way to tucson right now.

     That's good news -- between the leaking fuel and the broken pieces, I was afraid that you were in for some serious repair bills.   Hope it keeps up OK.
