Hi, I am brand new to this board and Vespa scooters in general. I have looked over several threads in the past few months but I couldn't find what I am looking for.

My friend had this 2005 Vespa ET4 150 from shortly after 2005, as the second owner. In 2011 or 2012 someone tried to steal it and did a find job messing up the the lock barrel. Without any money to fix it is sat sadly, for 4 years. Two months ago she moved out of state and asked if I wanted to purchase it. And I did, but after all this time she lost all the keys.

I have taken care of all the key problems and have all new keys, immobilizer, and lock barrels. I did some MX including and changing the plug, oil and brake fluid.

I drained the gas and it was a pretty green color. I cleaned the carb and included the dirty carb pic because I was impressed on how dirty it was. So I have put it all back together and once I got gas in the bowl it starts right up.

However, I ignored the settings of the main jet and the idle jet and just screwed them all the way in. It idles a wee bit rough (only I seem to notice) and seems to accelerate fine.

So...I know I should have recorded what they were set at and put them the way I found them, but hindsight is 20/20. Does anyone know what the factory settings for the idle and main jet?

Thanks in advance.

I was visiting a town that had a Vespa dealer and service center so I stopped in to ask the question. If anyone is curious, the main and idle jet, but they may have different names, are both tightened until snug.
