Lou I cannot discount anything you stated . I got into the newer engines irvines mainly the 53s and 46 conversions and it just became a second nature (TO ME)
larger props fuel economy ) (yes had to pipe the exhaust out of the way)
Just crank and go at field no glow starters ( and yes the spray cleaner and towels)
A lot of folks find that a bother along with the "truck smell". my 4 stroke glows toss
a lot of oil also in the exhaust so cleaning one or the other same thing to me. I guess
my main reason is not having an in flight quit (unless out of fuel) I had a few flights
where maybe I had CRS that they were grossly mal-adjusted but they still ran got
them down and reset the needle compression or both and off again. Then again
my old irvine 40 glow has never let me down and very little clean up, Getting off
the subject a little the irvine 53 is one of the best I have seen great transitions
super no hassel carbs AS GLOW or DIESEL No I am not trying to setoff the OS
fanatics I got a better deal on irvine had it been OS price wise would have been
them (I do have and OS40 and 52 in the 4 strk barn)
