This bleedin' Lespa (Vespa VBB frame converted for 10 inch, LML engine) I've got has always got somet up with it.
Leaving work last night and engine cut out after a few metres as though fuel tap was set to off and it had just used what was in the carb. I had not set the fuel tap to off but when I went to check it was very stiff and came off in my hand (ohh err matron) when I turned it.
So I need to get the fuel tank out and attach it again. Anyone fancy guding me through the process? Can't find how to do it on scooterhelp.
Ta,
Dan

Remove the 11mm bolts on top of the tank and you 'should' be able to lift the tank out enough to see the tap, there is usually enough slack in the fuel line to do that..
You need another pair of hands to reattach the lever, or balance the tank sideways on top of the frame, the lever is only attached with a D clip which will probably be floating around at the bottom of the frame.
Attach the lever, remove the grommet from the frame where it goes through and guide the lever back through the frame as you lower the tank back into place.
Grommet back in, bolt the tank down, job done!

Hey Bryno,
Yes, I had a go at this. Problem is that there is bugger all slack on the puel pipe (why not use a longer one to allow for this !?!). The tank isn't close to coming all the way out so I can't get to the fuel assembly.
Does this mean I have to in from the engine side and disconnect the pipe at that end? If so, how best to go about it?
Cheers.

Just disconnect the fuel line at the carb end, you need to take the box cover off to reach it, probably just a spring clip holding it on, easy enough to do but a bit of a faff.. yes, a longer fuel pipe would be sensible!

Hey. I just had a go now, had to remove the air filter too so I could get at the clip around the fuel pipe. As I budged the pipe a little bit though a fair bit of fuel came out, do I need to try and bung the pipe straight away after I remove it? There isn't much room to work with is there!
Cheers, Dan.

Depends if the tap is on or off now.. if it's stuck in the on position, I'd turn it off first gently using a pair of pliars on the front of the tap, you then just have the fuel in the pipe to spill everywhere! If you are going to remove it with the tap on, i'd clamp the pipe with some molegrips (and a piece of card to stop them cutting the pipe) inside the frame as close to the carb box as you can get, you've then just got the fuel in the end of the pipe to spill all over the paintowork  |

I'm guessing it is stuck in the off position as just before the lever came off I had the symptoms of it being off, engine ran for 20 seconds or so and then cut out (I guess after using what was already in the carb). Then again I had not set it to off so unless some scruff on the street did (quite possible!), it should be set to on, which would mean there is another problem then wouldn't it?  As I can't get to the fuel tap to adjust it I think it will be safer just to clamp it. Will try and borrow some mole grips from someone at work. Ta. |

Got this sorted eventually the other day. Fuel tap assembly had actually snapped and had to be replaced so the scoot shop sorted it.
Just gave the old girl a clean now and noticed that the large tube between the carb and going into a hole into the body of the scoot is missing altogether. What is it actually called and how crucial is it? (presume it's not just there for show and guessing it is related to air intake in the carb?).
Been on a couple of short runs since I've had it back and it seems okay. Going on a longer run tomorrow so I will soon find out if it's a problem!

The "large tube" is your air bellows, and yes it's quite important as on a standard set up the space under the seat is used as an airbox. Basically you'll find that you're running a bit weak without it.
Either get a new bellow and fit that or a useful upgrade is to fit a different filter (ramair etc,) directly to the carb box where the bellow used to fit. You'll have to upjet slightly but it does give a slightly better intake. If you do go this way you'll have to remove the standard carb filter and make sure you have the rubber seal fitted to the carb box.

Ta Joey. I'll get onto the cowboys at the shop and ask 'em why they decided to remove this part and not bother putting it back.
Last time I'm going there as my suspicions (that the fella is fly as f*ck!) were confirmed when I went down one of the scooter clubs the other night. None of them will go near him, known to be dodgy. There's another place further away that is supposed to be sound so will give them my business now.
