This is the correct flywheel (PN 6616) for all the 206 Briggs engines with the stock crankshaft and PVL ignition. It has a steel adjustable hub for making timing adjustments without taking the flywheel off or using an offset key. The aluminum fins are an integral part of the flywheel (not plastic bolt on fins) It has much stronger magnets that are capable of producing a very strong spark. It is a very nice piece!
It does not accept the ring gear for the onboard electric starter used on the World Formula engine! It also does not accept the cup for the pull / recoil / rope starter. It is designed to be used with a hand held electric starter.
Please note: Once it has been installed it is not returnable! No exceptions!!
