Ted Williams 7.5 Outboard

[rscholar]

A few weeks ago, I noticed gas coming out of the top of the bowl below the carburetor. I ended up buying a used float, because the used lawn mower place didn't have a new one. Not long after, the same problem happened, but instead of going and getting another float, I put some "seal-all" on it where I was sure it had a hole in it. Well, yesterday (11/4) I took my boat for a little spin around the lake to test a new electric trolling motor, but since my battery wasn't strong enough, I cranked up the ole Ted Willliams, knowing it was fixed. NOT! It was still throwing gas out of the top of the bowl. Before getting a new float, I was wondering if that is for sure the problem. Any help, much appreciated.

Even though the weather has been warm, here in Michigan the past few days. I guess I'll have all winter to get this question answered. I went out yesterday, to test drive a new/used trolling motor, then cranked up the ole 7.5, and gas is still coming out of the float bowl. My guess is it has to be a bad float?

Re: Ted Williams 7.5 Outboard

Well, I went to the Sears website, and ordered a new float bowl and float. It only takes 10 minutes to change out the float, so I'm hoping this is the fix!

Re: Ted Williams 7.5 Outboard

I received the new float from Sears yesterday. The float is made of either plastic or nylon...hmmm, hope it works. There was a little spring that came with the float, but the paper states, that if your carb. didn't have one to start with, don't use it. Any helpful hints from the mechanics out there?

Re: Ted Williams 7.5 Outboard...Still NEED some help, Please!

The new plastic/nylon float is installed, but the gas still flows out the top of the bowl when motor is running. When installing the new float, I noticed a small (less than 1/8 inch tube or rod) coming out of the carb. I couldn't install the float in the down position, without first encircling both the tube/rod and the other thing the float goes around. At first I thought the float was too small, but it did go around both things. I just think that the tube/rod thing (comes down at an angle) that it has to go around, hampers the float from rising all the way up to close the seat. I don't remember ever seeing this tube/rod before, but then again my memory is poor. Did this tube/rod thing fall down from some place in the carb., or is it suppose to be there? Can I bend it so the float goes around it freely? I sure could use some help on this frustrating ongoing problem! Thanks!!!!

Re: Ted Williams 7.5 Outboard

I reinstalled the float and new bowl. Since it has already begun to freeze and snow here in Michigan, getting on the lake to test it, isn't smart. I found a plastic 55 gallon drum, filled it w/water and ran the motor for about ten minutes, with no more gas coming out of the bowl. Maybe I got it FIXED! Yesterday, I purchased some Seafoam Deep Creep, sprayed some in the motor gas tank, sprayed some around the carb. (have no idea where the air intake is), and sprayed some in the spark plug hole, then pulled on the starter rope three or four times. I then put some new gear lube in the lower unit, covered it with a plastic tarp, and will see how everything goes in the Spring. Guess I did things right...got NO help on this forum though.

Re: Ted Williams 7.5 Outboard

Sorry you didn't get any help.Unfortunately your problem was pretty straight forward yet not a common problem with those motors thus no experience to be added. Your thinking was correct, but repairs didn't solve your problem.
It appears you have now solved your problem. Please give us another chance if you develope any more problems.

Re: Ted Williams 7.5 Outboard

Thanks for the reply Steelspike! I assure you, if I have another motor problem with my ole Ted Williams, I'll be asking questions/seeking answers. I'll even try to throw in any help I can with motor problems, that I encountered, and through hit and miss by golly fixed! Being on a fixed income (SS), I'll fiddle with anything, that I know won't totally destroy my little motor, with you guys/gals helping me. I threw in that little gripe when I noticed all the replies were mine. BTW, I still can't find the "air intake" on that carb.. I just sprayed Deep Creep in the throttle control slot (in front of the carb.), hoping it got into the carb./motor.

Re: Ted Williams 7.5 Outboard

Air intake is right where the choke plate is.90% of small outboards have a similar carb lay out with a choke plate and a throttle plate behind it.

Re: Ted Williams 7.5 Outboard

I'm sorry, but another problem, another question. The other day, I replaced the seat, valve needle, and both bowl gaskets. Ever since, it refuses to run! It will run, if I squeeze fuel mixture into the carb, but stops when just connected to internal or external gas tank. I took off the carb. and blew it out, I blew out all the fuel hoses, but no luck! Several days of trying to fix, and I'm totally perplexed!!!! (and frustraded) Any HELP?

Re: Ted Williams 7.5 Outboard

Possible solutions:

1. You may have the seat for the needle installed improperly. That carb uses a soft seat that must be installed properly, using a tool to press it up into the pocket where it goes. Also, if the old seat wasn't removed, the needle may not behave properly.

2. You could have a defective fuel pump element. That's the red rubber bladder that fits into the back of the mounting flange on the carb. It should be installed with the slot at 10 and 4 o'clock.

3. The thin fiber gasket/valve behind the fuel inlet flange may be defective or missing. It controls the flow of fuel from the fuel pump. If its leaves are curled or broken or stiff, the fuel pump won't work.

On the second two issues, the engine won't run after it uses up the fuel in the bowl, even with the internal tank. All that fuel pump stuff must be in place and working properly.

Good luck.

Re: Ted Williams 7.5 Outboard

Thanks Admiral! I only had gas coming out of the top of the bowl. So I went to get two new bowl gaskets. (one for the top of the bowl, and one for the screw at the bottom.) While at the shop, I decided to buy a new seat and needle valve too, even though I thought that wasn't the problem. I bought a punch to install the seat, but I think I pushed it up a bit to hard. I went to retrieved the new seat, and I think I put some cracks in it. I tried using it again anyway, but when it didn't stay running, I decided to put the old one back in. The problem is, when I went to get the cracked one out, I couldn't find it! I took the carb off, blew air in and out of all the fuel holes...still no seat! I put the older seat back in, and now it still refuses to run on its own, only when I spray gas in the carb with a spray bottle. Did I jam the new seat into someplace that I can't see it? I don't think I have a fuel pump.

Re: Ted Williams 7.5 Outboard

That seat is still in there. It's pretty deep in that cavity. The only way to get it out is to bend a very short hook sort of thing in a piece of stiff wire. It can be a real PITA. But keep trying.

You do have a fuel pump. It's that bladder that fits in the back of the carburetor flange where it attaches to the engine.

Re: Ted Williams 7.5 Outboard

Removing the viton seat: I would not recommend stiff wire, tends to scratch up the brass tube wall and can cause the needle valve to stick, preferred method would be a no.4 crochet hook or if your a brave soul you can use a drywall type screw, I'm speaking from experience here as I have gouged the heck out of the first one I ever changed and it cause the needle to stick.
My wife gets these little plastic crochet hooks she uses when she frost her hair that work great. also air pressure can blow them out pretty easy.

In the Eska service manual, they show a photo of the hook made of stiff wire. It has a very short 90% bend on one end...that's all. It worked great for me, with no scratching at all. But, then, I had the photo of the tool, so I made it exactly as it was shown. I can see how what you say could happen, though.

Re: Ted Williams 7.5 Outboard

Some viton seats come out real easy...just a little compressed air, old hard ones (like me)...lol you have to almost dig out. the long course drywall screw works real good for old hard ones...and the crochet hooks are the tool to have

also if you buy a kit with an already hard viton seat chances are it will leak, you want the new one to be kind of squishy

Re: Ted Williams 7.5 Outboard

Okay, I think I got the needle valve problem worked out, BUT now gas is coming out a hole on the top of the carburetor (like a bleeder hole). This is what the whole thing started over, I think, cause I saw gas coming out of the top, but thought it was the top bowl gasket. Do I put gum in that hole to stop the gas from coming out? The motor now runs, but I can't have gas spilling out the top!

Re: Ted Williams 7.5 Outboard

Check the float level and needle setting, that "hole" lets air in, an atmospheric thing, should only lose gas when turn upside down or tilted forward, what did you set you float at?

 

[rscholar]

Re: Ted Williams 7.5 Outboard

You are probably right. My neighbor is the one who discovered that the bowl has to be on just right to get the gas flowing. I saw him squeeze the tab on the float to hold the needle valve on it better. I didn't see how high the float was, but will check it out in the morning, and you guys know the outcome.

Re: Ted Williams 7.5 Outboard

I have the float set parallel to the carb. body, but still getting gas through that hole when running (while motor is in running position, not upside down).
