Hi everyone. So, heres the rundown just got my first moped off my neighbor its a Puch Maxi luxe 1HP the only reason i know this is the covers and vin plate say so. the throttle cable was broke when i got it i was able with dumb luck to get the right part from ebay. my first question is what year is my moped the vin plate says manufactured in 1977 does this mean its a 77 or a 78? if it helps the vin# is 9418218. Next question the filler plug on the side of the engine how do i check the level of the MYSTERY fluid thats right i have no clue what is in there or what to top it off with. How much should be in there if i drain it. Any and all help for the newby is gratefully accepted.
