I run my line trimmers on 25:1 even though the sticker recommends 50:1,I use a cheap 2 stroke oil and retune the carb for 25:1 ,I think they
last longer that way .

Hi Mowerfreak ,The mower is a total Bitsa ,I made it from rubbish,the gas lines are from old barbeques ,the four gas line
connectors are from a car wreckers,the gas regulator was a air compressor regulator,I put the barbeque
bottle in a car battery box with the gas tank mounting cradle made from old right angle steel from an old bed.

All up I did not spend over $10 for the complete mower with the gas conversion.

I have a forklift gas tank that I can fill at the service station and then I just transfer the gas from the larger tank
into the smaller BBQ tank.
