So, now i bought bigger carb for the 170cc, and i ended up with 34mm and free flowing air filter. I got no idea what main/idling jet i should start with. I hope theres someone who got same setup :D
doubt there will be, i'd start obviously rich on the main and do plug chops going down in size till its right/you'll feel if it starts running lean, pilot jet probably won't be far off with the carbs origional, the carb will have a setting for how the pilot air screw should be set so jet it till its running properly near that.
