Yes, the T just shows you that mark is the correct mark, rather than any orhers. Yeah that gap is probably printed on the label somewhete on your scooter (under the seat?)
So, please back up and fill in needed info.
Ok, this scooter is how old, how many miles, and was running just fine ----then you did what to it for what reason?
Or, explain what you were trying to fix, and why.....and still need info on scooter personals (age. Miles, etc)
