Thanks,
This past weekend I prepped and painted the new engine. It was nicely painted with a shade of blue with metal flake in it, not original and not something I could easily match with a spray can. because I removed some parts and needed to fix a few things it needed at least some paint, so I elected to paint the whole thing "alpine green" also not an original color but not very far off.
Before
After (did not repaint air cleaner)
Then Sunday I removed the old engine and put the new in.
It runs, flushing the cooling system here.
Made a little "dashboard" for the oil pressure gauge.
Also I found a new place to get the crankcase pulses for the fuel pump (I forgot to modify a cover prior to painting). See the hose going to one of the bolts on the water pump, it's a hollow bolt with a piece of 1/4" tube silver soldered in the head of it. This way uses a much shorter hose and it looks a little cleaner than the previous method any how.
Sorry for the shaky picture, it must have been running....
That's all good.
The bad part is it's not "new and never installed" like I was hoping and as the seller thought, as he had been told by the previous owner. While prepping it for the swap I had to rearrange the shifter on the transmission, remove thermostat housing, water pump, and remove the injector, change the oil, and chose to look in the crankcase. Most every part of it has been assembled with the old gaskets and a small amount of clear silicone. In the crank case I found a little water and some metal flakes (I made and installed a magnetic drain plug as a result). The injector however looked pretty near brand new, but signs that it had been removed at least once if not several times, the hold down clamp had also been installed upside down. The water jacket had some rust and crust in it and the thermostat and housing had white deposits on them, perhaps calcium. The head surface where the thermostat housing attaches is pretty well rusted and pitted. On the outside of the crank case are some severe rust pits mostly filled in and painted over, were hard to see when it was in it's wooden stand.
Worst part is the transmission has a little noise, perhaps the source of the metal flakes, and something I'll have to swap out soon, the other/old one seems quite good.
On the plus side is the whole thing even with a few hours on it appears to have had much lower use in comparison to the old engine. Between the two of them I should be set for spares and such for years to come, and I still think the price was reasonable given the apparent condition.
Now how it runs,
This one seems to also have good compression while hand cranking. But when starting it struggles to run, like the children's sorry about the train "I think I can. I think I can. I think I can...." eventually it will get up to speed. However if I press the cold start button, which allows more fuel to be injected, either prior to starting or while it is "thinking it can" then with a little black smoke it quickly starts and or gets to speed.
It also seems to me that it won't idle down as low or as smoothly as the other engine.
Could these be signs of overly advanced timing?
