The cast metal spark arrestors are a little taller than those used on the GP-12s but no model is perfect (at least not mine). Prototypically the spark arrestors sat on an upside down ‘|_|’ metal frame which the exhaust stack fit through. To simulate the frame I cut six Evergreen 1” x 10” pieces and acc glued these to the bottom of the casting getting the plastic flush with the outside of the spark arrestor. I still need to make the exhaust piece wider.
