This one has a Presto Lite mag on it....have yet to find any more info on it, everyone i come across has a WICO, and all the manuals i find are for WICO also. I am also hoping that a good tune up and new set of wires and plugs would sure help out on the power issue, not to much fun to have one guy on the ground shooting ether and me throwing the lever from start to compression and back just before the pony chokes down to a dead stop!!!
The old guy who had it before us would pull start it when he needed to use it and couldn't get the pony runnin!!! I never even knew you could pull start a 25ton dozer!!!😊
I'll get some pictures as soon as i get the old girl home, took the camera with me this weekend, but i was so excited to get it running that i forgot about the pic's until i was half way home!!! lol
Lot of things to pay attention too aren't there with these, use care with that ether too. I think Autolite or NGK may be the desirable plug for these, though I forget what heat range is best, that and copper wire. Not sure what the deal is with the magnetos, but they came with Eisemann and or Bosch American if I am correct. There are some internal differences, the Wico X... whatever model that is, is different under the cap.
I always warn or pontificate to great length about those starting motors, keep the oil clean in them, check for thinning with gasoline, change same if you suspect it's been thinned down, the carb can leak down, good to run them out, turn off the sediment bowl, or use a petcock in the bottom of the bowl, drain it down, keep a hand on the governor linkage when the diesel fires, in case it wants to overspeed the pony. You will probably have to clean the fuel system, tank, lines, sediment bowl, if the tank is rusty, put a high rise screen on it if need be, you can clean that tank by putting crushed stone in it and sloshing around, flush out and refill. The Zenith carb is easy to work on, you can clean that out, don't drill any of the orifices, just clean em, they sure like fuel to run strong. I worked on mine and got it running pretty good, would fire from the handcrank, but that electric starter sure makes that pony fire quickly.
