Re: identify my carb for rebuild

so no sense in even cleaning the carb just for the sake of it? i sprayed carb cleaner over the summer on 2 occasions.
I am going to check the fuel filter..i have the carter pump so i was going to take the filter out, clean it up and put it back in.
looking at the diagram..i cant find what the choke coil looks like? can anyone describe what it is plz?

Re: identify my carb for rebuild

A simple rebuild is something any boat may need if the engine's been sitting around for very long. The modern 90/10 gasoline breaks down very quickly, and acids produced eats rubber parts.

Luckily, a 2 stroke carb. seldom needs any carb kit, and the parts are very easy to disassemble and clean with carb. cleaner.

Re: identify my carb for rebuild

The coil Don is talking about is the autochoke coil inside the autochoke housing. There are 3 small screws on the housing edge. Unscrew the heat stove riser tube from the housing, then carefully remove them and you'll see the coil, and the arm from the choke butterfly that should be engaging it.

You can do whatever you want to the carb, but it's not going to fix either one of your problems.

i sprayed carb cleaner over the summer on 2 occasions.

Spraying the outside of a carb may make you feel better, but it does nothing for the inner working of the carb.

I am going to check the fuel filter..i have the carter pump so i was going to take the filter out, clean it up and put it back in.

The filter has nothing to do with your fuel pump problem. The problem is a leaky diaphram, that is what causes gas to get into that clear hose going to the carb. When you see fuel in that hose, you need a new fuel pump.

.i cant find what the choke coil looks like? can anyone describe what it is plz?

Here is your picture showing your choke coil. It's electric, no tube to the manifold. You still need to remove the 3 screws and check the spring to see if it's broke, or the lever is broke or it's just out of adjustment. The manual shows the choke and how to adjust it, but you have to actually look at the manual. You should have downloaded the manual to your computer, then you can read it on the computer. Then just print the pages you need.

Quite right... I just checked the manual and there was never an electric choke carb on the 2.5l engines. Which means, he has a newer carb, probably from a 3.0l.... Might answer a few questions.... like why he can't find a number on it...

Well, that's just wizard! The parts manual shows ONLY a heat stove auto choke, but the service manual shows an electric choke!

Both produced by Mercury Marine, go figure...

So, what does that have to do with the OP's question about his '88 120 with pictures that show the electric choke.

Oh my gosh the earth just stop spinning...... Mercruiser Gods made a mistake... LOL

Re: identify my carb for rebuild

I don't know what Chris is looking at, but the choke coil for the 84 is electric, on both the Rochester and the Mercarb.
Exactly the same thing as the OP.
Trust me, Merc makes lots of mistakes. Half the manuals show the wrong wiring on the ignition switch, old and new.

I will pickup 1 of you guys & drive you over to his carb. Good thing it is a simple 2 bbl. It may be running by spring time.

How much gas has he pumped in to the engine from the fuel pump? Did it clean it as well as SEA FOAM ?

Did you not follow the discussion?

Re: identify my carb for rebuild

That doesn't show either one, only the carb. Go to the Fuel pump and Carburetor section both old and new designs and see what you find. Once you find the choke cover, look at the part number. That number is for an electric cover.

As for the rebuild, not sure you can get a kit. You may have to piece one together.

The choke stat/spring whatever is listed under "carb & linkage". I found it by accident intentionally looking around! Vintage was 83 -84.

Re: identify my carb for rebuild

I am a novice mechanic. When I rebuilt the carburetor from my 4.3L V6 (I think it is a Rochester /Merc two barrel) the hardest part of the job was getting the screws loose that held the top of the carburetor on. Had to go to auto parts store to get paint remover to remove the black coating. The screws were really tight. Two mechanics told me I needed the custom width screw drivers from Snap-On to best remove the screws. Managed to get them loose but it was a tremendous effort. One of the screws was pretty beat up. Lucky I didn't have to drill it out. Any suggestions on how best to approach?

Re: identify my carb for rebuild

I had my carb "rebuilt" (Mercruiser 4.3 engine) by a marine mechanic and it still leaks. I've been told by another (mercruiser certified) mechanic that the majority of marine carburetors cannot be rebuilt properly and I'm better off buying a remanufactured one. I guess if you are going to do it yourself it's worth a try but i wound up spending almost as much to have mine rebuilt as it would have cost to buy a remanufactured carb and install it myself.

Leaking internally or externally? What type of carburettor?

BOLLOCKS!!!! Not a lot of difference (but the differences ARE important) between a marine carb and an auto carb. Most use the same kit.

Seen that a few times! Friend of mine had to have his done while I was away. They charged him over $750. A new Edelbrock 1409 is only $599.... Rip off merchants!!!
