I recently purchased a 1965 Vespa 150 with a 17/20 carburetor that has a cover over the jets. Does this jet cover need to be installed? Or can I remove it without hurting the engine?

Are you talking about the piece stamped 140? You definitely want that and the proper sized air filter for that carb. If you dont, you'll get a lot of blowback and could get something sucked into the carb/ rotary inlet.

Yes the part stamped 140 is the cover in question. I just had the air filter removed to take the photo. Do you know why later oem and replacement carbs have exposed jets?
