RE: Rules for 2 stroke engine's break-in
I would suggest you remove the cowl, if your breaking in an engine....heat is good in small doses,,,even if you break it in in the air,,remove the cowl....the problem with 4 stroking an engine, is that it raises compression and cools the engine down and just puts more work on brand new surfaces...I have several Norvels, wierdest breakin ever,,soak the engine liner in motor oil for 24 hours, before you crank it up...but after about the 3rd tank, you can actually hear that engine come to life in the air, its like flippin a switch, anyone who's heard it knows......ooop there it is!!....she's broke in now....a week ago I cobbled together a cox .049 out of several engines and if fired up and ran good, third tank, it locked up tight,,but cooled down and still runs fine and I use extra castor in all my engines....just some ramblings....Rog
