Hello I am in need of some info on some motors I have.The motors in question are the OS MAX40H and the OS MAX30S.I have 2 of each and both sets are new.I have over the years heard of the 40H being a good stunt motor.Are they run stock?and what size venturi ect.Also I have heard of the 35S being used but not much about the 30S.Is this just due to displacment?Also again what size venturi for the 30S.Thanks for any info ect.I also ended up with some parts new in packages for the 40H if you are in a pinch.Thanks Dennis

The 35S and the 30S use the same nva and venturi as the paperwork in my engine boxes show. The carbs are also the same p/n for both engines. Hope this helps.
