HI guys,
I am going through my just arrived 1968 JD350 crawler loader, looking after all the neglected maintenance items collected over the years, and am now working on restoring normal power to the machine.
When she's cold, she smokes grey, and as it warms up, smoke turns blue, then after working the machine for 10 minutes, the smoke all goes away. In those first 10 minutes though, it's a gutless wonder, at almost full throttle, just opening the clam shell almost stalls it. Putting it in 3rd and rolling away same thing. Smoke also changes color as the load changes, from grey to greyish blue. After it thoroughly warms up, it seems okay, although not as snappy as my other first gen 350. It almost seems like the governor is stuck, it comes up to speed very slowly after a load is applied, sometimes never comes back to full speed.
Things I have checked so far.
1. Air intake system...filter was rusted, plugged and disgusting. Removed that and cleaned everything. No difference.
2. Tank drained and all fresh fuel.
3. Checked fuel supply to the IP, pumps like crazy at the input to the IP just cranking the engine.
4. Checked output fuel flow from the IP while running, flows clean. Removed top cover of IP looking for mouse turds, none found, clean.
When I refilled the tank, I added about a cup of ATF to help clean things up, also put a little in the crankcase. I haven't checked the timing. The IP looks like it has been serviced at some point in its' life. It comes up nice and clean with just a blow nozzle. Fresh safety wires.
The machine has sat for the last 3 years with no movement. The fellow started it once in a while but never drove it around.
I have run it around for about an hour or so in the last few days with no real change.
What else should/could I be looking at?
Your thoughts?
Thanks!
