Hi anon, the usual ratio for most 2 stroke engines is 40:1. The 1 being two stroke oil

Hello,

On that particular sparkplug the gap should be set to 0.025 inch (0.635 mm).

Hope this helps,

If it is a 2 cycle motor, then use an appropriate 2 cycle oil. I use a synthetic oil that 1 bottle is mixed with 1 gallon of fresh gas.

Don't know that exact trimmer, but I always run 40:1 in all my trimmers, chainsaws, etc. That is 3.2 oz. of 2 cycle oil to one gallon of gasoline. I rebuild these machines daily and run that mix in everyting, except when it's actually specified on the machine.

Straight Gas no mix for a 4 cycle.
