Re: what year is it
TD-20s were offered from 1946 to 1949, so the 1948 indication makes sense.
Great little engine, Kelly. Treat her right and she will outlive your grandchildren.
Modern fuel mix is 24:1, 5 gallons 87 octane gas and 1 quart TC-W3 outboard oil.
Spark plugs should be Champion J6C or J8C (I prefer the J6C) gapped at .030".
The magneto points are set at .020".
Keep in touch, and good luck.
