Modern Vespa

Anyone experiencing a similar problem. This bike was always a one or two kick to start even after being stired for months. Had the carb apart today cleaning it and everything looks good. Even started when I primed with fuel. As soon as the fuel burned off though that was it. Tried to remove fuel tank but the fuel on/off switch seems to be in the way of removing tank. Dont want to break anything. It seems maune the fuel line is clogged or something. Any quick fixes, or suggestions to get me rolling again. Thanks.

Still best to pull the tank. You just have point the fuel tap handle straight up and tip the tank forward a little when you are taking it out. There should be a rubber grommet around the fuel tap rod, take it off before removing and you will see that there is plenty of room for the handle to pass thru.

Yeah thats what I was probably gonna do. Thanks for the feedback about the fuel tap handle. Im gonna try that on my next day off.

Another tip: when you are going to reinstall the tank, point the lever straight up again and tie a piece of string to the handle end. Run the string thru the hole from the inside so when you are lowering the tank into position (tilted forward of course), have someone else pull on the line to get the handle thru the hole so it does not jam up against the body.

Take the fuel hose off at the carb end (again) and blow up in to the tank. You should here bubbles if its full or air if its low
It takes a hell of a lot of crap to completely block a tank/hose..and youd see this down the hole

with the hose off the carb you can also play with the lever to see when it flows or doesn't.

Its quite common to reinstall the lever 18O degrees out....no biggie...it still works....but the C and R will be in different places.

with the hose off (and cup to catch it)establish which position allows it to flow..or even just dribble...then get on to cleaning the tank.

Ive done road side bodges by sloshing it around and then lying the scoot down to drain the fuel ( and crap)..then top up with good stuff

"Tipping and blowing will get you going"

Pulling the tank is more civilised

I tried that yesterday. The tipping and blowing method. It must be real clogged because even moving from c to r I was getting no fuel at all. Not even a little dribble. So I think the removal of the tank is the next step. Thanks again.

I had similar issue... It ended up being the flywheel keyway woodruff key had sheared & flywheel had spun around

??Looks like SEB is replying to another thread..the flywheel is not related to a blocked tank.

Once the tank is out you will see the base of the fuel tap....some have a bowl held on by wire clip and a wee wheel for tightening..pretty logical

Others have no bowl

Behind the lever on all taps , held by two screws is a mesh filter.

Im more concerned with whats blocking it ....if its dirt that ok....if its rust then the tank will need attention

Yeah i hope its not rust. The bike has been sitting for a while with no fuel. I know when the fuel sits for a while it seperates. So hopefully it wont be anything major. Will find out tomorrow though.

Just had tank off and the fuel selector switch was all clogged up. I had to clean real good and drain fuel. When I got it all done the fuel began to flow again. No rust the tank was a little dirty but I cleaned it pretty good. The old bike started right up like usual but then the throttle cable broke. So now on to fixing that. Oh well I guess thats how it goes. Thanks for all the help everyone.
