Thread: 1987 Force 85hp motor, carburetor rebuild gonna happen.

a torn diaphragm can sure enough lead to troubled waters .....just saying

When I first got the Other Woman I paid a shop to tear down and replace the needles and seats and any other parts that would become suspect after many years of sitting in used. They took off the bowls, blew them out with carb cleaner and replaced the bowl gaskets, called it done. The second mechanic I took it to had to do them properly and my issues disappeared. The issues they created along with a few other items made me wonder if I hadn’t bought into something I should have left alone. The second mechanic, Buddy who’s now gone from us, took care of my boat as it was his own and I had no issues other than normal wear and maintenance for the ten years I owned the boat. My thought is to do whatever you spend the time to tear into complete and mark it off the list of possible gremlins. So I’m guessing that you’ll open the holes before resetting the gasket this time. Dremel tool maybe? I’m patiently awaiting fish pictures, I won’t lie.

And maybe we're talking two different things. Yes there are tiny wire holders for the needle, but I'm talking about the seat for the needle, which is what I did not replace. They are rubber (green rubber) and held in place with a circular piece of wire. We're getting into the weeds, but if you look at 7:25 into this video you'll see what I'm talking about.

The other part of the reason I did not replace those is the stupid kits I bought did not include them. They looked fine to my eye. So hopefully the real problem I am having is with the torn fuel pump diaphragm which I found.

I see what you are talking about. Looks like a little snap ring that holds the seat in place. Use a pick to remove and a tiny socket to replace.
Piece of cake!! Lol

So why is long before an update. While putting the fuel pump together I tore the gasket and had to get a new one. Since I was ordering a new one anyway I bought new valves and screen and other gaskets as well. Fuel pump is now rebuilt too. Yay

And I fired her up with the hose on the muffs. Ran great. Idles way too high now so I backed off the idle screw link 3/4 of an inch and she ran wonderfully. On the water might be another story but I'm pleased so far. I'll be putting her in the water in the next day or so. Awaiting another part I wanna install before doing so just cause it'll be easier to install on dry land. Hopefully it comes tomorrow and we'll get her wet again. Yay

Glad you got it all rebuilt

Good luck with the whole project. Sounds like you will soon be on a tear for spring crappie.

Good deal, hope she runs good for you.

This is a good story. You brought the boat and motor back to life.
