AAC engine break-in
I know it's probably been asked or discussed a few times on here but I didn't know what to ask for in the search engine....so here goes. Picked up a Collari AAC motor (.21 onroad)new(but no instructions or box)....is there any difference in the break-in procedure for these AAC types versus ABC type engines? I've never owned an AAC engine and I want to make sure I break it in right? Thanks
