Re: size of orfice in carb.NEED HELP

You have an '86 engine, the first of the 225 loopers. That year there were various carburetor problems with it and various changes to them over the years. You will need to find a dealer who is familiar with those older motors and has the service literature and service notes from back then.

those orifices you mention are air jets, not fuel jets, so size does make a difference

Are you checking the idle while the boat is in the water, or on a flushing hose? If on a hose, the idle rpm will be much higher and louder.

Have decide on a course of action will order jets that omc parts manual calls for and try them if have problems with them will drill them out until i get the results im looking for 650-700 rpm at idle in gear I have equitment to make jig to hold orfice while drilling etc. IF THIS dose not work I WILL up date hate to leave post open with out problem solved.
