AR3910 gap size clone?

[kartracer1979]

Hello does anybody know what the correct gap would be for this plug on a purple plate clone? Thanks

Try .030 and see how that works out, I dont have alot of experience with that plug though, I use the 3910X plug

Use the 3910X as well, as per engine builder.
