Manufacturer specs may differ but if the engine displacement is around 30cc or is a 31cc 2 stroke, the fuel to oil (2-cycle oil) should be approx. 32:1. 32 parts fuel to 1 part oil
I like the Yard-Man 31cc 2-cycle String Trimmer .
40:1
32:1
it uses a RDJ7Y
32:1 gas/ oil I have one and the mixture was on it.
Suggestions, Increase bore. Increase stroke. Raise compression ratio. Improve exhaust flow through port matching and non restrictive muffler. Install larger carburetor. Install performance camshaft. Balance all rotating parts. Rokcney

I saw online at a lawn/garden website that they are interchangeable.I have 4 troy bilt attachments and I need to know if they'll interchange with the craftsman weedeater also.Because craftsman has a good deal on 31cc 2 cycle for only 119.00 and I'm thinking about buying it.Does anyone know for 100% that these craftsman and troy bilt attachments are interchangeable?
I have a Bolens Model BL 150, 31cc and my Operator's Manual calls for a spark plug gap of 0.020 in. (0.5 mm).
