one more merc 225 ?

[jsr21]

Hi..when I have my 1994 225 idling with the cowl and carb cover off, the upper right carb butterfly pops and spits about every 5-10 seconds. I think I remember reading once this might be a reed problem? The only one that does it is the top right one. thanx

G,day<br />Could be one of a number of problems.<br />sounds like the carby is running lean, I would strip the carbys and clean, reassamble. If it still spits then try richening the fuel mixture. I think that this model had adjustable idle jets.
