I've read through prior topics regarding the 6hp to 8hp carb change. On my model J6REIA the manifold ,exhaust ,leaf plate are the same as the 8hp model. (According to part #'s) The carb and the cylinder/ crank appear to be different. If I put a 8hp carb on my 6hp will I get more top end speed or is the different cylinder/crank a deal breaker? Can anyone point me in the right direction ? Thanks for any assistance
 
No one has any experience with this? The 6 and 8 are the same except for the carb and the cylinder/crank. Will I go faster with the 8 hp carb? Thanks
