The engine model would be our question. The 200 Ficht engines really are/were not bad motors. The 200 carb engines were a little thirsty, though fairly durable. We did not sell many Ficht engines, though many are still running in the 200 size. Other sizes are different in the expectations. If that is a 150 carb engine (Intruder), then jump on it. They are great motors. BCB
