OS 46 LA/ OS 46 FX- What's the difference?
FX has ball bearings and a real carb! LA has no ball bearings and a dinky carb.
FX makes horsepower and the LA is a slug.
Problem I see with the LA is flyers are always trying to get more power out of them so they keep leaning them out and end up ruining them. Look and see how many post there are on RCU asking , "How do I get more power out of my LA?"
Get a 46fx. A great engine!!
