Mikuni Carb/ Rotary Valve

[petron]

I recently rebuilt my mikuni carbs for my 1996 Sea Doo GSX.

During the carb cleaning I also disassembled the engine top end for inspection and replacement of o'rings.

Upon reinstalling carb to engine I got thinking about the Rotary Valve. During the top end inspection I spun engine a few times.

Do I have to spin shaft so the Rotary Valve is sitting in a certain position before installing carbs?

Thanks guys

As long as you never took the RV off, or at least put it in the same location, you will be fine.

Re: Mikuni Carb/ Rotary Valve

It sounds like you are saying that you have removed the rotary valve cover and maybe the rotary valve too ?
If so, then yes, you must retime the rotary valve. A guide to doing that is available here at the SBT website.
