Morning everyone,
I was off Monday and decided to see if I could try and figure out the why my tractor (67 Gas Deluxe w/ Z145) would idle well but cut out at Higher RPM's.
I was able to get the choke all the way in at times but generally I had to leave it halfway out and the throttle lever halfway as well. The carburetor's main needle was set at the manual 1 1/2 turns out.
I got into my field and as I was heading home the tractor cut out and I started to do the idiot checklist. I had an extra condenser so I replaced it, cleaned the sediment bowl, there was some slight crud where the gas flows into the bowl from the tank, removed that and it seemed to run better. At times the RPM's on the tachometer seemed surge to a max of 2200RPM and settle down to 1100-1500 RPMs.
There were two things I did notice, the throttle lever did seem to move by itself. I'm about to order the cork and thrust washer and replace them, the other was that when I re-installed the sediment bowl, I had to let the bowl hang and fill with gas and then tighten the knob. Does this mean that my gas cap is faulty and potentially restricting gas flow?
Here is also some video shot with my phone demonstrating what it's doing.
