Alright, when I am at a stoplight and want to start off easy I start in high 3 at 1,200 RPM, it dies down a lot, I go full throttle and about 2,000 RPM I clutch in to go to High 4, and it revs all the way into the black part, and the MPH Tac comes down into the white! Also if I go from a high idle to full throttle under no load it does this, but will eventually govern back after about 2 1/2 seconds, not sure why.
This is on a 1971 or 1973 International 1066 with the DT466 engine, and a rotary pump.
This only seems to happen when it is at an operating temperature, I am running 15-40. If the engine is 'warm' or 'cold' than it won't do any of this, and I can start from idle in High 4....
The fuel is only turned up about 1 turn, It has somewhere around 4,480 hours and runs great, accept for governing.
I feel like it could be an issue with governor spring or something with the weights slipping. Anybody got a solution for this, and what it could possibly cost to rebuild myself or have a shop rebuild it?
