Carb crud

Think I will go the safe route on this carb and use the Gumout spray . Don’t want to press my luck. Thanks.

You can use the OMC Engine Tuner on any part of the carb. Mercury has their version too. It’s not hard on your hands, but does have a pungent odor (ammonia). My wife actually likes it. It makes the brass look brand new if soaked overnight. I have heard the Pine Sol works well, but haven’t tried it yet. Bought a sonic cleaner so I will be trying it soon. Was that an after market service manual? I would be surprised if OMC recommended Gumout. Never knew them to recommend a carb cleaner of that sort. Interesting?

The 1989 Factory OMC 9.9/10/14/15/20/25/28/30/35 Service Manual has a photo in the carb section of the spray Gumout in use by the person cleaning the carb.The manual didn’t refer to Gumout specifically. It read "never clean a carb by submerging or soaking it in a hot tank or carburetor cleaner. Do not expose plastic or rubber parts to any carb cleaner" and "clean parts with a mild aerosol solvent". In the past i used the Engine Tuner on 3 different carbs,with great results. I wouldn’t use either cleaner on the plastic carb top or float bowl.
EDIT for Correct info

Again, I plead ignorance. 1989 is too new an antique for me. Although it is rapidly approaching the magic 30 years old mark which qualifies it as a aomci "classic".

But from the OMC Factory service manual part number 507758, covering "CE" (1989) Loop V models. Hey, all I know is what I read in the book. Seems to be an awful lot of plastic involved. This info, plus $1.79 will get you a cup of coffee at the Raceway Gas Station over on the corner.

Well there it is! My apologies. I am surprised they recommended an aerosol carb cleaner. I have never seen that done. I spent all my time in the big motor manuals. I stand corrected.
The Engine Tuner & Mercury Power Tune won’t hurt any of the carb parts. Plastic, rubber, or other wise. It is water soluble too.

I’ve been using PowerTune/ Engine tuner to clean carb’s for a long, long time. I spray it through the carb, then follow up with a rinsing of aerosol carb cleaner. My personal preference is B12 ChemTool. Lastly, I use compressed air to check all passages. The Power Tune will clean the worst varnish and gum deposits quickly. It’s nasty stuff so wear gloves and have good ventilation! I have a friend of mine that’s a Mercury instructor…. he used to always say that marine mechanics life spans will be shorter because all of the chemicals and exaust fumes we work around. He may be right.

always used protective eyegear to keep that stuff away from your regular eye glasses

some sprays will dissolve expensive coatings on eyewear if splashed in your face !!!

Not sure but simple green might be the ticket. Call a dealer & let us know.

Very likely he is right.

Never too late to work smarter,using gloves and protective eyewear.I know it’s kinda hard wearing gloves sometimes.
