Hi i got a question...I have the o.s. fs120III 4 stroke for my mustang that im breaking in. I set the high and low needles as per instructions but when i try to accelerate the engine looses power and shuts off, i have to back off the throttle just to keep the engine running. i tried leaning the low end but doesnt help.Any ideas? Also the instructions say i dont need a line from tank to muffler.

So would this be equal to about a .25 or .40 (2 stroke)?

This engine runs on a max of 15% nitro based glow fuel..
Its cheap and bloody relieable...

What plane do you plan on or have you put this in. It's a very affordable 4-stroke, have you had any issues with it?
