Should look like this sir.

Just was wondering if anyone has seen these #"s before

We need more info on your setup. Carb size ? Carb number ? Motor details ? I personally have never seen numbers like that..and I'll bet that you'll just end up with a standard 6.5 power valve. But please give us all the info.

i think all of mine are 4.5 if my memory is right. i also have a b&m 250 blower
