Swapping engines in a piece if equipment. Taking out 300 inline 6 ford gas and putting in a 329 deere diesel. Throttle now pushes and I need to pull. Whats the easiest way to achieve that. I was going to change the linkage but where it is is a very limited space to work. Al.ost like if I could mount a box in the engine bay that converts push to pull. Is there such a thing?
