It's the TPS .455. Trainer Power System.
The Alpha is a .40 in a .46 case, with a 46 carb and cylinder. It has decent power for a trainer engine.
The .46 has the crankpin farther out on the counterbalance for a longer stroke. The liner is thinner than the Alpha for a larger bore. You can turn the Alpha into a 46 with those parts.
My .455 is my best 2 stroke. Tons of power with an A3. It turns a 11x7 fine.
Evolution made it easy to get the engines mixed up.
