Ernest, I think if you clean the plate a little better you will find that the model is a GG 18805a and you are correct, it is a 1963, 40 horse Gale (which was an OMC brand sold mostly through hardware stores etc - Montgomery Wards in the case of yours).
And yes, you can run unleaded gas (86 or 87 octane) mixed at 24:1 with TCW-3 rated oil with good results. However, you may want to replace all the gas lines under the "hood", if original they were never designed to handle the ethanol in modern fuel - it tends to eat the older rubber... |
