Hey all, my Gurtner issue was multiple. 1) vacuum fuel tap was bad. I replaced it with a new one, set the air/fuel mix to 1.5 out and away we go! 2) the lines on the tap were reversed when i picked it up. I didnt know. I do now! 3) the elec-choke works on the bench but is suspect on the bike. Although the scooter runs well enough, i think theres a wiring issue to it.
Indeed. Thank you. The little Minarelli 50 rips now! I still need to sort out the start button, and the cracked front mudguard, but that doesn't belong here. This was about the PY12. Thanks for the replies!
