Here we go again.... I was over at my friend Chris' house yesterday and saw his beautiful Summit 3 sitting sadly on the garage floor with cobwebs between the gear legs and flatspotted Tettra wheels.

I've got to get this beauty in the air so I need some help.

Some of you may remember Chris asking for help with his RF-P not running correctly. Just to re-cap, the idle is inconsistant and surging and high RPM varies. Some times you can throttle up and its good (11500) and sometimes it struggles. It also dumps a ton of fuel out of the carb after you shut it down.

We have swapped the 86 carb for a known good 86 carb with no change. Since he obtained this engine used, the previous owner may have messed with the pump (there's no paint on the screws).

First of all, is the SF-P and RF-P pump the same? I'd like to swap the pump from my known good running SF-P and see what happens.
Second, does anyone have experience adjusting the pump to help get this thing back on track?

If all else fails, I'm pulling it and installing a brand new YS .61 AR.
