I have a 2004 Nissan 40 HP TLDI tiller model. It will not start and continue to run with the throttle all the way closed. With the throttle left on the closed or START position it will sputter and die after catching within a second or so. If I turn the throttle half way open or more, I can get it to start and continue running. However, I cannot get it to run below 2000 rpm (I connected a tach). If I try to ease the throttle down even after a good warmup below 2000 rpm it dies.
I reset the TPS according to the service manual and replaced the 3 spark plugs with correct (expensive) type. I also ran the diagnostic.
Diagnostic shows 1000 rpm on Tach with the center and right two warning lights steady ON. When this is looked up, it means engine hours are between 95-149 hours. It does not correspond to any component failure in the service manual that I can see.
Fuel is brand new fresh and in a brand new fuel tank as well.
BTW, the tach I am using is a Teleflex and the switch on the back is set to the 2 pole position. Is this correct?
Any ideas?
