I have a 02 yamaha 200 2 stroke. I added some fuel cleaner octane boost and idle jumped up too high. I have since added 30 gals. to fuel tank. I run chevron gas and standard tc3 west marine 2 cycle oil. I am wondering if anyone has had a similar experience and if there was a way to manually adjust the idle. I also need to get the owners manual. Any suggestions would be greatly appreciated.
