Question, and new results!
First the results:
tighten the loose throttle cable upgrade
1/2 tank of fuel
Which is better than my last 69.5! Just running better today i guess!
Now for my question. After i got the jetworx and pump plug kit, i notice a high pitched whine when i take off slowly. Just for a second. I dont know if maybe the impeller is ringing off the wear ring or something like that? i dont know if this is normal or not. Please advise.

still no ideas on that little whining noise? I should note that it goes away after i ride through its frequency (rpm level)....

wish i could, but ive got to work. Im sure it'll be fine. If something flys off, or catches fire, we'll know we've got a problem.

That type of noise is usually the pump bearings going out. Remove the pump and spin it by hand and see how it feels.

agree with fercho
i had no rpm loss..just the above and my engine ran slightly hotter. I pulled it apart and water poured out of my pump brgs. Fixed it properly , corrected the cause, and whine went away. Chk'd my pump last week (after last yrs rebuild) and it's perfect.

Its possible, but I had the pump out a couple of times and they felt fine.
