RE: thunder tiger break in
of course they are allowed to disagree with me.......thats fine, but you miss a very important point- read #2 and I do say 'high rpm and rich'. Refer also to my prop diameter, smaller than flying propeller, we have to get the heat up very quickly for expansion of the liner.
Contrary to your commets I believe a fair amount of cleansing does occur at the initial running, anything offensive left in the engine at time of manufacture will be tossed out the exhaust port in a similar way to the gloplug element disappearing- have you ever found one inside your engine, coz I certainly haven't! I use enya #3 plugs................ trevor h[:@]nz
