motobravo euro classic 150cc help with bottom hose on carb! By chinacrapper (Read 4,414 times)

OK all I just joined and I'm sure I will be a frequent flyer here. The wife spotted this Motobravo online and it was right in our town for cheap so we bought it, it's a 2007 with 1300 miles. Anyway so here is my ordeal someone has been in there blocking off some lines etc. My main concern is I had the second hose up from the bottom of the carb leaking from age. Well I couldn't get any line at the moment so borrowed a piece off of the very bottom hose on the carb. Now here is the strange part that hose (has a spring like thing and a metal piece on the end) was just hanging there not connected to anything hence why I figured it didn't have much purpose so borrowed some of the hose to repair the other. Anyway The one above it is repaired but now the bottom one now pours out fuel! I have only worked on cars so don't know much about scooters or carbs for that matter. I have a pic but don't know how to post. Any input appreciated!

That hose with a spring on it and the metal piece on the end of it is your Carb Drain hose. Now there should be a screw on the end of it. So put that piece of hose left with the metal piece and the screw on the end of it back on the Drain connector at the bottom of the carb. If it fubared then just get a piece of hose and bend it over and zip tie so it stops the fuel from emptying the carb bowl.

Thanks Alleyoop that's exactly what I needed to know! It had no screw in it so was just pouring right through it.

Ok now the pos won't start! I knew this thing would be frustrating lol! Kick stand up, have the panels off, love these great stripping screws of butter! Here is another strange thing when we bought it and started it electric it would not start until you basically stood up and slammed down on the seat could that be? Wife all excited me not so much!

China crapper walk away and come back to it when your not frustrated with it. Look at the library section you might find some helpful info.

[jvino]

Sounds like the starter might be bad. You could try tapping the starter with end of a screw driver might tell you whether it is it.

At this point best is to take pictures of the carb area and hoses. Something may not be connected right.

Good news, the carb was loose and sucking air on the inlet side. Battery all charged up and the thing fires right up. Now the real test how long can it remain problem free! for the input guys, I will post pics next time something arises.

How long can it stay problem free? What time is it?

I'm baaaack! Ok I thought I had a fuel pump problem because the fuel filter would not fill up with much gas. Installed new one and still hesitates and will bog out and die after prolonged full throttle about of 2-3 miles. It's pretty warm here 95+ but I still have not figured out where that metal piece off the bottom hose of the carb goes and it's missing the screw. I just have the hose off the bottom of carb and hose from overflow of gas tank zip tied up to the frame right under the seat. I'm not riding it until I resolve this issue stall along the road sucks lol!And my exhaust just got loud out of the blue as well yeeha!

Loud exhaust. Something is leaking. Check where the muffler mounts to the exhaust manifold. They come loose fairly often if you don't lock them down good.

Bogging down, I think you still have a carb problem and you might need to adjust the valves. I think valves because it does it when it gets hot.

Lets have a couple pix of your bike. And some of the engine, carb, muffler connections.... Stuff like that.

I will take some pics today when I tear it down a bit, it still has the cheap red spark plus as well so will get an NGK in there.

Ok how do I post pics, sorry long hot day so too lazy to use the search function. Tore this thing down, the exhaust leak was that rubber hose thing had gotten brittle and broke. I was able to reattach it but it wouldn't slip on very far due to the thing being old and crusty now. Can I use some regular heater hose type line or do I need to order it, it's a pretty good bend so would kink I assume. Took the carb off pulled the bowl, it's really clean however there was no fuel in the bowl when I took it off, normal? Air filter wasn't bad gave it a quick rinse like it said on the cover so letting it dry. I live at about 4500 elevation so not sure if this would be a factor. I also still need to figure out the metal thing that is missing the screw, can I put any screw that will fit or is that some special screw? Lots of missing bolts when taking apart go figure, these things can really get time consuming when they act up!

Ok hopefully this shows the pics..
