Hasn't been running since 1963. Use to run like a champ up until put outback under a pile of old stuff. Had to clean the points plunger but after that fired up on first pull just like the good old days. That old girls idles down to a really nice putt...putt.There are just a few questions I have about it. 1. The lean/rich lever where should that be set after it warms up? In the middle or all of the way lean? Or do you futz with it til it seems right?2. What is the gas oil mixture. I have seen everything from 40:1 to 20:1. I can't find the recommended ratio for that particular motor. 3. Where does the grease or crank oil go into the case? I can't find anything that looks like a plug let alone a dip stick.4. Does anyone have a manual for this model or recognize it from the picture. It was made by Gale for Goodyear but that's all that I have been able to find out about it. I think it may be the 3 hp model. The model number and serial number has gone by way of the rest of the paint.5. Which leads me to my next question whether to repaint it or not. Is it a sin to destroy the years patina?Thanks as always,Frank
