The Fox .36 R/C was one of Fox's best engines. You will like it.

Be sure to use a fuel with lots of oil and with some castor in it.

If the carb has a flat plate instead of a rotary drum, it will adjust backwards from other engines. Tell your helpers, if you have any, to open the high speed needle 1.5 turns and then adjust the low end adjustment until the engine runs well. Then you can adjust the high speed adjustment. Doing it the other way around, like standard engines, will make everyone swear up and down that Fox engines are junk and that the carbs are not good. I used to get more free engines from people simply because they assumed they knew it all and didn't bother with the instructions.

Have fun.
