mcman56 Posted 3 hours ago Report Share Posted 3 hours ago I have a TY250A with two spark plug holes. Did they come that way or could it be an aftermarket head? Online parts lists don't seem to show two but a drawing in the service manual looks to have two. I remember having a DT1 with a compression release but don't know if it was OEM or after market.
