What the fork is this thing? (pictures included!)

here are the piccies
Resting out of its plug. Scooter runs fine.

it usually fits on the black tap thing here. Scooter coughs and has a hard time running.

back off again. scooter runs fine again.

My scooter is registered as a 'nifty fifty' 1985 model. No real name like 'elite' or whatever so I'm not 100% as to what it is other than it IS a honda build, however the pictures on each of the manuals do not match the same shell mine has. Which is odd but anyway, to the point.

To the left of the air filter shell, is a single tube that loops from a lower point on the engine to another point slightly above. It situates itself behind the kickstarter and, for some reason, if connected to the (what I assume is) correct part of the motor, causes the motor to start with alot of difficulty, however if i REMOVE the pipes loop, letting it rest outwards, the engine often starts on its first kick (battery is nearly dead,. starter doesnt work, engine still runs well on its alternator etc.) and it runs best without it connected.

This tube doesnt seem to contain any liquid, nor does it seem mostly important as the engine continues to run. Is it an air intake valve or something? Its very difficult to figure out *scratches head* If anyone can shead some light on this it would be great

Okay. I'll probably upload pictures later if people have trouble figureing out what I'm trying to describe.

The Nifty 50 is the same a a Honda Spree, I don't know alot about the Spree's so I will let somebody else try to answer your question. But as far as I know the Nifty 50 is just another name that was used on the Spree's. I believe it would be a NQ50.

SB50 and some US Elite 50 carbs have those tubes, but that said I have no idea what they are supposed to do either.

[Ziraya]

it doesn't really seem to fit there all that well

if you can, try to adjust the part you left it on to get rid of that kink

[XaNtHuS]

Even with the kink pressed out it doesnt do much different. The entire fact that the engine doesnt run at all rather than restricted. It has to be something to do with air flow... It still runs fine without it though so blegh.

[XaNtHuS]

c'mon fellers theres gotta be someone out there that has some sort of idea.

[Clivester]

Is there a bystarter anywhere on that carb?

Almost looks to me like someone stuck that odd-shaped tube into the bystarter recess. Could this have been done because they bystarter was removed and this was just shoved in there to allow it to run????

The other tube would maybe just be the float bowl vent that was modded with the metal L connector. If you ever remove the carb you can tell because that tube would connect to a hole at the top of the float bowl.

I thought i read somewhere on this forum that nifty 50s have a manual choke, if so thats why its in the bystarter's usual spot
