- The fuel fittings installed on the carb are somewhat fragile. You can't place a side that has a fitting face-down and hammer on the opposite side, or something will break.
- Instead of spending $8 on an impact screwdriver, I should have spent $30 (with a coupon) on an electric impact wrench. You will need one or the other, but I suggest the one that doesn't require a hammer to operate.
- Take your time prying off the old O clamps. Pay attention to what you're resting your tool against for leverage, or something will break.
- Although all passages and gaskets were already clean and in good shape, I had a significant difference in pop-off points for one carb pair. 1 was 38psi, and the other was 27psi. I have researched acceptable differences and have come to the conclusion that difference should not be more than 6psi (I'm know that's debatable.) My point here is that although everything looked clean and good, performing the actual tests revealed a problem. So I ordered all new arm springs.
- Don't throw away your old accelerator pump hose until you extract the recharge jets from within the hose.
- If I had to ever do it again, I would sell my old carbs on Ebay and order brand new ones from OSD. In my opinion, the cost would be about equal after taking into account: rebuild kits, new springs, tools, cleaners, blood, sweat, tears, hassle, gas going to/from Harbor Freight several times, time spent researching, and time spent off the water. OSD Sea Doo 787 800 Dual Carb Set
- The experience I gained from doing this myself just 1 time is enough to where I feel very confident attempting to tune and retune the carbs on the water. I know what conditions to look for, and I know how to address those conditions. I look forward to having a true push-button start and smooth idle!!
Big Thanks to all those members who helped me out along the way.
