Hey any of you Iseki guys.I am looking for some info on the 2AA1 Isuzu engine. I am trying to get my Bobcat 533 skid steer going. It has the same engine. Parts are ridiculous to find for these engines. I did find some from Dessco and some from Ebay. I got engine back together but have some parts missing and am needing some info on some parts. There is a spring going from the throttle lever on injector pump to a bracket which I don't have either of them. I can probably buy a spring and make a bracket but need to know how long a spring. Pics would be great.And some other parts. Can any of you guys help me out.I would greatly appreciate it.
