39/8/1: Briggs & Stratton LA One of my in-laws found this so-called lawn mower in an old building on a farmstead he recently purchased. I would appreciate any information any of your readers could contribute. The engine is a Briggs & Stratton Model LA, engine no. 37331. According to information available to me, the engine was built between 1931 and 1932.

Any information on the mower would be very much appreciated. Harlan Ternes, 5335 Fair hill Road, Bismarck, ND 58503-8019; (701) 220-7665.

A: We're betting the mower is a home-built unit. That said, the addition of a transmission (we're assuming it's geared to increase blade speed) is interesting.

39/8/2: Maytag Fuel Mixture? I have been told that chainsaw fuel mix should not be used for Maytag engines. I understand that non-detergent engine oil and gasoline should be mixed, instead.

What mix ratio of oil to gasoline should be used? Also, what weight of oil is recommended? Ron Shipley, 1110 Riley Ave., Emporia, KS 66801.

A: Good question. We've seen references ranging from 1/2-pint regular oil to 1 -pint regular oil (not two-stroke) per gallon of gas. Maytag owners?
