The 140-Sport is stronger than the old 140-FZ, It has the  140-L Carb, Piston 
and the new rotary valve now used on the 140-DZ they have  gone back to 
pressure through the crank shaft to the diaphragm which also  improves lubrication 
to the cam area similar to the old air chambers the only  problem we have 
seen, and there are five of them being used locally is that the  hole in the 
throttle barrel on the low end side needs to be drilled out to 1/8"  diameter to 
eliminate the mid range from loading up. we are running Magnum  1-1/2 fuel, 
16x11APC and turning 8400 to 8800 two of these are on Temptations  and two on my 
original designed Eagle One Larry Mercer was third in Advanced at  the Nat's 
with his.
