^ I dunno, I've seen alotta the hobbit kits just maladjusted and would hit. the wizard kits all did that, the athenas sometimes needed up to 3mm bas gaskets? I dunno why hobbits. on the cheaper kits like the 77 cast iron and the wizard ones I think they just milled the bas to get everything flat, and so some of em the just went very far and you had to make up for it with base gaskets. dumb, but real.
Anyway I've definitely seen plenty of hobbit kits slam a proper spark plug and needing spacing.
