regardless of what the instructions say, the proper way for an ABC/ABN 2 cycle breakin does not change. so even what they suggest may not be ideal. give it the correct non-4 cycling 2 min run heat cycle cool down runs. even if the directions say to 4 cycle it, savvy engine folks know thats wrong. even most of us know OS 4 cycling breakin method is totally incorrect for abc/abn 2 stroke engines. go with the 2 min runs at a semi rich non 4 cycling and let cool down fully between runs.
