Combines Want to turn up the fuel on 1680

The fuel can be turned up on the 466 quite easily. One quarter turn on the fuel screw will get you about a 10% bump up without causing any problems, any more than that you better be careful. Been there, done that on a 1480,it works.

I have a 1440 with a 436 no turbo, will this engine turn up the same wayIJAlso where is the fuel screw located on the pumpIJ thanks junkman
