I believe the OS venturies also work on GO and Novarossi engines as well.

I am not real sure where everyone gets that you have to replace bearings in V-specs but I have had 4 of them and I have put 25 gallons in 3 of them so that is 9 gallons on two of them and 7 in the last one and then I got a lemon on this last one and it lasted about 3/4 of a gallon but I have yet to do anything to those other three
