I have a JD 350 has been run hard and not serviced for years. When I got it I went through the basic service and replaced many worn out and damaged parts. Ran great 6 years. working on pond sudden loss all power would maybe run at fast idle no odd noises. Has CBC injector pump. That being said I went through the fuel system all appears well. no bubbles leaks etc. Now not running at all. Found a 3164 out of a wheel tractor has a JDB331MD2406 pump I am starting with pump rebuild then engine rebuild with swap to 3164. Pump has an extra spring that was inside item 93 fig 10-10-75-DB (SM 2045) it is 5/16 dia 1 3/16 long it is not item 90. I can not find anywhere that it would go I don't know if it just got there by a bad rebuild or what. Also I need help with item 128 same figure. I believe it is in the photo but it was installed large end toward inlet.[/img]
