And how did you fit them??? OS carbs are 13mm with the insulator.....Nova carbs are 12mm?? Picco carbs are also 12mm.....
With respect as to which engine is better for a novice on to Nitro, I'd go with and OS engine....I'm not saying with this, if it is a better performance engine than a JL /Picco, or a Nova based engine, I'm just saying that based on my experience OS engine is simpler tos tune and lasts longer....
