Hi, Bill.<br /><br />Welcome to iboats. <br /><br />Model 4416 is a 1947 2HP, Bill.<br /><br />Spark plug is Champion J8C gapped at .030". Set points at .020". Use a 24:1 fuel mix.
If you will settle for under $350 use the iboats Thrifties.<br /><br />If it looks good and will start and run well it ought to be worth a couple hundred.<br /><br />If it is pristine, like new, I would check with AOMCI.<br /><br />Good luck.
