Hello Forum, please forgive me and redirect me if this topic's already been covered. I've seen some reference to my problem, but not exactly....
Tractor is a JD650 (it's 2 cylinder Yanmar diesel). The throttle is tough to move at startup, but it seems to loosen up a bit once the engine's been running for a while. The linkage is fine, it's the control arm on the injector pump which is tough to move. I've always used a diesel additive to lubricate the pump, so I don't think it's my fuel?
Is there any fix for this, or am I destined for a pump rebuild/replacement?
Thanks for your help...
