Ok ron, the instructions are the same as included in all the other "brand name" kits...I won't get into how that happens!
No real secrets in 'em, just follow the "adjustment" matrix, I've found that to be accurate for the IH apps. Sometimes the accel pump "slot" May need to be changed, you do whatever makes it work best, not what any "spec" sez!
And you've already seen, yours May/May not have all the "extra" add-ons that are shown in the exploded view, just be concerned with your carb!
One tip...tighten the main body-to-throttle body screws so tight you are on the verge of stripping! That is the most essential "secret" to doing these and will make this rebuild last for an extended period of time.
Also, the power valve actuator piston should be removed for cleaning/polishing and inspection, make sure the bore it rides in is spotless! When re-assembled it must run smoothly in and out with no hint of "drag" or "chatter".
Other than that, all parts must be clean as in sterile if possible! Regarding these mixers, it's a fine line between great and crap! Moreso than any other carb I work with!
