Decarbing a 200hp Evinrude/Finding the Carberator

I admit I'm a moron. Went to decarb my '93 200hp Evinrude, took off the cover and removed the plugs and sprayed decarb in cylinders. The problem is, I can't seem to find a carburator or an air intake to spray decarb that way. Does this engine even have a carburator? Where do I spray the decarb besides in the spark plug sockets? :eek:

I endorse Rickdb1boat's recommendation to use that method for decarbing - I just think it's easier, but don't know if it's more effective than the way you're trying.<br /><br />But even if you didn't need access to the carbs for decarbonization (is that a word?), you'll want to get at them for fall fogging probably.<br /><br />So, to answer your question: Yes, it has carbs you gotta have faith! In fact, it may have three!<br /><br />Unless it's fuel injected, in which case ignore the following.<br /><br />I am not familiar with your engine. But just in case no one else responds (not bloody likely?): My (older than yours) Johnson V6's carbs are covered by a large black plastic air intake. As I look at the engine with the cover off, this black plastic thing dominates the entire front of the engine, pretty much from top to bottom. On the front, it has no openings. On it's sides, kind of slanted rearward, it has 3 large air intakes on each side for a total of 6. It is fastened to the engine by many hex head screws around it's perimeter, some of which are a little difficult to remove and replace because of clearance issues.<br /><br />Under that cover/air intake are the carbs. You can see evidence of them looking around and behind the air intake, but you really can't see the openings of the carbs. It's kind of like a car - the air cleaner covers the carb(s).<br /><br />On my engine, once the air intake is removed, there are three obvious carbs stacked vertically on the front of the engine block. Even if I had never paid for fuel for my engine, just looking at those three things in a row, I would just KNOW that it is a gas guzzler (which it is!).<br /><br />Hope this helps a little.

D.-<br />That's actually very helpful. I think I know exactly what you mean. I saw that large black cover with the hex bolts and I wondered if it might be covering the carburetors; just didn't want to start taking things apart without knowing. I'll give it a try. Thanks.

Don't drop those screws!

Yep, don't drop the screws. I've done that too.<br /><br />You might want to get a manual to build your confidence. I rebuilt my carbs several months back and the manual helped a bunch. Lots of pictures helped as well as the text.<br /><br />I also just decarbed my 50HP Johnson using the technique described in the link already provided. It seemed to work well although I don't think I had too much carbon built up so it didn't smoke too badly when I did it.

I just invested a couple bucks in two screw grabbing things - a telescoping magnet (like a telescoping antenna) and a magic wand with a trigger controlled grabber on the end. On the "bargain" table at NAPA. One of those deals where you just smack yourself in the head and wonder why you didn't buy these as your first tool purchase way back when you bought your first set of sockets. Why didn't my grandpa tell me this?
