Just picked up this 1978 Vespa Grande with only 406 miles on it. It is in great shape, but I have a question or two about how to get it up and running.
First, I noticed a little knob just under and behind the seat post, you can twist it tight or loosen it... what does it do?? I was thinking is a air ventilation hole for the fuel tank...
Also, the fuel valve is entirely missing. Do guys know where I can buy a new one? I'm gonna try looking on 1977mopeds.com and mopedjunkyard.com, my two go-to sites... but if you can help me that would be great too...
Next, if the carb needs to be cleaned (I'm gonna try to run the bike without cleaning the carb first, just in case there is no need...), how do I get to it? Do I remove the big bolt on the front/top of the engine that appears to support it? Kinda like dropping the engine on my Honda Hobbit?
Thanks in advance for your replies,
