'73 50 hp carb little tiny wire clip lost

[FillupD]

I have a question about a carb and the little wire clip that connects the needle and the float together.
I have lost one of mine off of a 50 hp evinrude and was wondering if I needed to make one out of a thin piece of wire or will it hurt to leave it off?
Also I popped my fuel pump apart and looked at the rubber diaphram and put it back together and it seems to work. The manual says that it is not serviceable.
Did it get ruined after I popped it apart? It is a 50 hp 1973.
I was having problems with RPM's <3000 at WOT so I am going to clean my carbs again and thought I would check the pump too.

your fuel pump should be fine. I have taken mine apart and it still works fine. now the metal clip on the float, I believe that when the carb was assembled when new, it did not have that clip. but the rebuild kits now include it. so you probably don't really need it. but you could also look at it this way, it was included in the kit for a reason. I guess its up to you whether it should be there or not

It is there because the needles sometimes stick, especially after storage. The weight of the float helps to pull them loose.

A dealer may have them on hand or can get them easily. Part #336842.

Thanks alot, I'll get the clip coming today. Thanks for the part number and thanks for the encouraging words about the pump.

Where's the old one you took out? Or are you saying you took the carb apart and plan to reuse all the old parts?

Re: '73 50 hp carb little tiny wire clip lost

I had a freind put carb kits in both carbs and the high speed jet got plugged up with some gunk(I think because it was running slow at WOT) He said new clips came in the kit with no spares. (They should come with at least one idiot spare.) So, I took the bowls off to clean out the jets and noticed one of the little clips didn't look like it was on very well so I took it off and when trying to reinstall it, it fell on my garage floor and it simply disapperared.
He thought the jets where clean when he put them back together but there must have been something in the hose for the fuel delivery. I am replaceing all the hoses before reasembly. Wish I would have thought about that before.
Hope this finally makes the motor run correctly.

I grew up in auto shops. All little spring clips were referred to as "Jesus" clips, based on what you said when they disappeared onto the shop floor or, worse, into the intake manifold.

I finally magnetized the tiny pair of needlenosed pliers I used on those clips. Worked very nicely.

I crawled around yeserday and drug a magnet around and couldn't find that clip. I swept up the floor and it was no where. Today I brought my bowls home from being soaked all day and walked in my garage and there that little bouger was, right in plain sight. Isn't that a gas. Carbs back on and idles and revs great. Taking off to the lake now. If this doesn't run WOT now I may have a motor for sale!

OK, I'm still only getting around 3000 RPM WOT. I moved the Full Advance Stop Screw 15 turns out so the ring advanced more and it made no difference in the WOT RPM's but it still seemed like it ran OK. The throttle is open full. The cam is in the center of the mark.
What can be wrong that it will not run proper RPM's under load?
Carbs rebuilt with new kit
14,000 volts at each coil with no load
Good looking spark with spark tester.

I took this motor from a 15' fiberglass boat and put it on a 16' Lund V-Bottom. A 35 pushed it around great. This 50 hp motor is the same length. Could the prop be way off?

Re: '73 50 hp carb little tiny wire clip lost

My cam and marks look like the photo on page 5-71 #11. I have my flywheel off and I can move the ring when in neutral. There is a screw on the side that will tighten it up but I have to screw it all the way in.
I believe now that my problem is adjustments. I don't understand the sync thing. Isn't it that your carbs open at the same time and the cam is in the center of the mark? Should you be able to grab the linkage from the ring and move it around a little?
I just need to start with what position the ring should be in and I think I can make the adjustments. I don't know for sure what to do at this point. I have done so much with this motor I'm getting really confused.
Would appreciate any help.

Do not move the Full Advance Stop Screw unless you are checking the timing. You now have no idea what your full advance timing is.

Re: '73 50 hp carb little tiny wire clip lost

I set the timing at 19 degree at 3000 rpm. because that is all it would rev to. See my post about milky gas. New problems seem to be cropping up.
