99 1200xl pop-off pressure

[steelroe]

I am currently rebuilding a 1200xl (power valve) engine and carbs for a guy.

Today I started the carb rebuild and noticed that the carb fitted with the acc pump had a gold spring fitted and the other 2 have silver springs.

My question is what is the stock combination of needle/seat and spring. Also what should the pop-off be stock?
All 3 carbs are fitted with 1.2 N+S.

Don't be concerned about the color of the springs. What's important is pop off pressure and it should be 55-60 on each carb. If you don't have 55-60, change the spring color until you do. There are 4 different springs, and all 4 are included in the rebuild kits from SBT. You can also get springs, needles, jets from John at Watercraft Superstore. All I know about the needle/seat combination is that if the rubber cone is in good condition, it's fine.
