perfect, thanks! Think I may be after 140 jets instead of 145. Will have to check.
The carbs are going on a tohatsu 50 so need rejetted to suit.
I'm going to get it running on the current jets but I've spoken to guys using yamaha 70 carbs on a tohatsu 50 and they're using 135 or 140 main jets.
The carbs are from a 1997 model yamaha.
