Quick back ground info, I got my 115 faststrike in july of 2013 and hung it on my 681C, It ran well, compression good, idle was good. I ran over 30 gallons of gas through it that summer-fall. But something didn't seem right even through it ran well and did well on my boat. I got 44mph out of it, not bad I thought... But it still didn't feel right, Any else one ever get that feeling that even though all was right, it didn't feel like it was?

Fast forward, its winter I got a new to me motor, I thought I would do a carb rebuild and general tune up. keep in mind I have not done anything to the motor but new plugs, thermo stats and LU oil change

Well I got my rebuild kits for my carbs. I set out to rebuild them, everything was going smoothly, pretty strait forward. Reading my manual and going at it, having fun...

I also bought a set of CCMS reeds, in hopes they give it a little more boost and it also gives me a good reason to look deeper in my motor (because I had that feeling I mentioned earlier). I couldn't justify pulling the whole fuel system off just to look around (even though that's essentially what I was doing)

Got the carbs all rebuilt, nothing out of the ordinary they looked pretty good. So I dug in deeper to get out my reed cages. Everything came apart easily and I set the first reed cage on my work bench and this little guy was staring me in the face (see first photo).

WOW!!! never have I seen this before. Who knows how long its been there, or how it got there. By the up close wear marks I say much longer than I have owned it. I was shocked it didn't make my motor run terrible. The motor seemed to run good, also when looking at a used motor who checks the reed cages before buying? But I will say had it got through that last little bit, myself and the motor would be very sad.

Needless to say I was happy with my decision to get my new reeds

Anyway enjoy the photos.

Your a lucky man! Any idea of its origin?

I have no idea its origin, all my screws were accounted for in the disassembly so it isn't like I was short a screw somewhere.

Here is the crazy part, there is a silencer box on the carbs, its bottom isn't level with the bottom of the carbs. So it had to have a perfect bump to jump in the carb throat.

After the perfect bump to jump it had to go around my main jet in the card, most likely another bump to jump around it.

After the main jet I have a manifold bracket that houses the butterfly valve. Probably at 3/4 throttle is the opening big enough for the screw to make it through, but again it had to jump up to make it past that.

Once past the butterfly valve, the screw has a wide open road to the reed cage. But if you look at where the screw is at, its not the bottom reed pedal, its in the third one up, again this screw defied gravity at the perfect time to have the reed open enough (which is like .05 of a second at idle or like .007 of a second at WOT) to get its foot in the door enough to take hold and make a home.

How long its been there, I have no idea. It could have came from the factory that way, I do not know

WOW! more than likely it came from the factory like that. Like you say the odds of a screw getting to that point are so slim. Although it just teaches one thing for certain. Follow those feelings! and if you feel lucky, on the way to the little lady , buy a lottery ticket FIRST!

I'd say a Factory screw up.... It looks like a screw that holds the reeds on
(similar size, without the washer)
It's weird that the Motor didn't run rougher.
