Hi everyone. Normally my motor runs at about 5300-5400 RPM (on my gauge) Got it out this spring and now can only get 4200 RPM out of it. Had it out again yesterday and noticed a tiny little hiccup (for lack of better term) every so often while running up the lake. was pretty subtle and only for a split second but did it several times. I use good fuel and add marine stabil. Can anyone tell me what may cause either of these issues and if they are related? thank you very much.
