Might want to print this out.
ABC Engine break in: 1) Find a large parking lot
2) Remove the body. leave it off for break in.
3) Use the same fuel for break-in as you would for normal running.
4) Set the main needle valve according to the engine manufacturer's specifications (e.g.,2 to 3 turns counterclockwise from closed.)
5)Open the idle needle several turns so the engine shuts off abruptly throttled back.
6) Start the engine
7) Advance the throttle to 1/2. Listen for 4-cycling. Lean the mixture to a rich 2-cycle operation.
8)Run the car in a 100 foot diameter circle. Keep the throttle at 1/2 and listen for 4 cycling. DON'T LET THIS HAPPEN! If it does immediatly lean the main fuel needle a little at a time until the engine produces a clean, steady 2-cycle sound. Run the car in a circle for 1 min. Do this up to at least up to 20-25 mins to be safe to be extra safe do 30 mins total.
Hope this helps.
