I just got this yesterday and would like to know what size it is.





What are the 2 lines that are circled for? The go to the carburetor.





It runs but I have to hold my hand on the intake and kind of restrict it a little. What should I do to make it run without doing so?

 

First thing you will need to do is get an airbox and filter for it. Looks like the prior owner ( or someone ) replaced the box with a automotive style radiator hose.
Look on the engine.....not sure which side ( probably the right side ) but you should see the engine size CC's.
The two hoses look as if the go to the carb...atmospheric vents.

 

It's a 280cc and the lines do run to the carburetor. The one looks like it was attached to something. It's shaped like it would have a fitting in it, the other is broke off. If there is something I need to put there I need to know what it is so I can find one. As for the intake I'm gonna take the white plastic pipe out and get a radiator hose and rUn it from the carburetor all the way out the top and put a filter on top.
