I can't get these carbs to pop off right at all.
1996 seadoo GTI.
Problem is, the needle and seat won't seal up right. I rebuilt them once before with SBT kits. When setting the pop off pressure, it always leaked just a little before the pop off pressure would hit. I didn't think it was a big deal because it was just a little and only a few psi before target pop off. Threw them back on the ski and its got a no start now...I'm assuming the engine is flooding because the needle/seats are leaking.
Came here and did more research and bought genuine mikuni kits. They do NOT come with the needle/seat like some people say. So I bought the needle and seats and the springs from SBT.
I bought 1.2, 1.5, 2.0 needle seats as well as all 4 types of springs. Tired of waiting on shipping.
I have literally installed every single needle/seat into the carb with at least 95-115g springs...and they STILL leak right out of the box. My lever arm is even with the chamber. I fill the seat with WD40 before I even put the needle in. I then fill the ENTIRE chamber with wd-40. And it STILL leaks with like 5psi. I have to remove the entire needle (removing the lever too) and literally just try reinstalling it about 4-5 times each before it won't leak below 10psi. Yet, it always leaks a bit before target pop off.
WTF. Are the SBT needle/seats really just that terrible garbage? Am I doing something wrong? Where can I get better quality needle/seats?
