I have a tentative plan for the access cover, but before that, starboard carbs are resisting achieving correct pop-off.
Manual spec is 40-56. Port, one carb with new parts came out at 48, and the other was high until I used one of the old levers to match.
Updating this post as I keep screwing with it and get more info:
Starboard MAG with all-new parts popped at 60+. Old levers were even higher. Bending the lever up to get 55 makes it contact the diaphragm and not hold pressure. But, the old needle pops at 56 with a flat lever. Short spring from the kit pops <40 (same as the port carbs), so that won't work.
Starboard PTO is off-the-charts high and won't pop at all with any combination of parts and the spring that's in there. The short spring and the old lever from the MAG carb (bent very slightly down) pops at 56.
So that matches, and is barely in-spec, but involves using two different springs.
It looks like stock part #270500267 is supposed to be 80g?, and based on
I'm looking at 95g in here right now. So that could explain why pop-off is higher than port (except IIRC my port springs were also silver and intermediate-length), but I have zero idea why all else being equal, PTO is so much higher than MAG.
Thoughts?
