I am going to try some synthetic oil and I am wondering what it will do to my zenoah 23 cc
magneto motor I hear that it might increase the rpm . I am running 25:1 the new syn oil
says it should run at 40:1 well this worries me...... I get some oil on the bottom of the plane
but my engine runs and runs and runs . I bought ACE hardware brand syn oil 40: 1
It is used in alot of out door equipment . When I change to syn oil will I need to adjust carb
Which way richer or leaner
