The Yanmar 1500D is back together with a new clutch. After several trials of air bleeding it started up. Now another problem, the diesel engine runs at full speed. I have tried moving the throttle. Throttle forward is supposed to be slower - back is faster but there is little speed change if any where ever the throttle is set. When started the tach ramps up quickly and reads over 3000 rpm. Thankfully I read some of the posts the other night and recalled that the only way way to stop a diesel is to cut off the fuel. I closed the fuel shut off valve and the engine shut down. I started it again and still the engine ran up to full speed again. I tried to control the speed by the closing and opening the fuel shut off valve but it either ran full speed or died as I tried to maintain a set speed.
Even though the linkage is not binding, I removed the throttle linkage at the connection on the arm where the shaft goes into the engine. Still the same when operating the arm without the throttle linkage or lever. When operating the arm by hand without the linkage there seems to be resistance by a spring (concealed). Maybe something is frozen inside.
I am afraid to run this thing at such a high rpm. I don't want to have it fly apart. I am wondering if I will ever get some use out of it. Any ideas?
