Wore out three sets of tires already!
You are working with a 2 strokeoitboard so think outboard. Way back in this strung I posted about the AOMCI Antique outboard club. Go to their website. Join, post in the blog the model of your Evinrude and find out what carb they used. Great group of guys, Bri and I both can attest to that. Post the model and ser# of your motor here, I might be able to help. I have tons of reference litersture and contacys. I have a few NOS champion plugs for 30's 2 stroke outboards of various heat ranges too....I don't really think I want to sell it just yet. After what I spent on that little engine I'd like to find a carb and take it for a spin at the very least...
