I had a posted a few weeks ago on my 1486 not having enough power and it kind got out of hand. I still have the same problem. I KNOW it's not putting out the power it should. You said the fuel lines, they are the correct lines not home made ones. The filters have been changed, fuel and air. The pump has been rebuilt and also the injectors. I have not had it on a dyno but from running IH tractors all my life I know. I know my 1466 is turning atleast 20hp over but the 86 won't hold a candle to it. When rebuilt they told me they set it up 10% but when I got it back could not tell any difference. the timing is set on 18. I backed out the fuel screw out myself one round and no difference. When you put it under a heavy load it just pulls down. Here is a example, I can pull a hay trailer, 12 round bales, up a pretty steap hill here where I live thats 1/4 mile long, my 1466 will pull the hill in High 4 and keep going and the 86 will have to go down to high 2. Any ideas???
