Hey Gents,I have a few engines that have come my way without any starter housing which means of course no model numbers.I like to de-coke the engines I sell which means 99% of the time a new gasket is needed. It is always nice to have one atleast orded before I pull the motor down but without model numbers I find it a bit iffy to pre-order. It would all so be nice to give it to the new owner with atleast the right series numbers.Any tips would be muchly appreciated.
