Crud in the rear carb pump
This is what was inside of the rear carb pump. The screws weren't even snug, They were almost loose enough to turn by hand. You think this would cause a "no plug color" symptom on that plug? We went from 1.25 out to 2.5 turns out & the color was always a light pinkish color while the other plugs ( cyl 1 & 2) were light tan @ 1.5 out.
All jetting is the same:
shiney silver spring (85?)
Looks like water was getting in there 'cause I see water stains on the carbs on #2 & 3 carbs. #2 carb was similar to this but not as bad & only 2 screws were not very snug. **note pic rear carb 4.jpg.** If you look closely you'll see the valve has a small crease in it & is lifted up from the surface. Will this need to be replaced?
I'm an idiot.
This is the front carb.. WOW, this makes things even more confusing now. The front carb was showing a nice tan on the plugs at 1.5 out. But then again, this cyl has been worked on 2 times now & maybe this is why? Sorry for the mess up..

That check valve needs to be replaced. Replace them all while your in there.

Change your filters at least once per season, and use some thread sealant (not locker) on your screws in the future.

Reassemble and pressure test the carbs about 3 pounds less than the pop-off and make sure it holds it. My experience after lookingat an oring like that is that it needs to be replaced.
