I will be glad when I get my new parts so that I can make my motor come alive.(roto start- pull start sucks!!) I leaned it down about 1/8 to 1/4 turn already and I have noticed an increadable amount of power gain. My friend did a temp reading yesterday and I was running around 260f after running 1 tank of fuel through it.( this is after the break in process) I did all that was reccomended by sts and you guys for break in. I am sure that I should use more 50-80 percent throttle before going full blast. There is no drag when I turn the motor over without a plug in it. I did notice that the motor , while running rich, likes glow plugs. I have replaced 3, #3 plugs already in less than 1/2 gallon of gas. This weekend should be the final break in process of the truck, after Sunday I should have 3/4 to 1 gallon through the motor. But I still dont see this sts28 pullin the wheels off of the ground on a heavy savage. Just my opinion. I am happy with the motor, However I guess the
OS 21 will be passin me up. Thats bad to let a Tmaxx pass you...
