Where are you located mate? Dee Why says it's an hour away from you on Google Maps, but I guess traffic is a factor also.
The only way to learn is give it a go, so don't worry I played around with carbs many times and had no idea what I was doing, but slowly you figure it out. Of course thanks to the Internet it's much easier to find info on tuning them than it was 16 or so years ago.
What is the F3 by the way?
Give me a call 0434 520 498 we can have a chat, might be able to come down this weekend.
