HD-25 plugs and gap

[tanjam]

I have a 1947 HD-25 2.5 horse Johnson . We have gotten the motor un-seized now I need to know what type pug's we need and what to gap the plug's to. I would really love to get this little motor running. Thank's for any info anyone can give....

i do believe champion j6c or j4c, gapped at .030 should be what you need.
