my viewpoints on the use of the type 4,,,,,for reliable service all aspects
must be set up properly ,not guess work or it's close. my type 4 is a stock 71
mm crank, with a big bore kit, the bore size is not important,,the
compression ratio is! i use 8 to 1 comp. to make the engine live a long life,,
8 to 1
comp. or less . also the timing set to 26 degrees or less! also a egt & cht on
all 4 cyls. i run 1200 egt max& 375 cht max sensed on the plugs. another
point is to balance the engine. the prop must be wood & balanced on the engine
too. i run 100ll avgas only& the oil press @ 50psi @ 3000rpm which is max in
flight. i cruise @ 2400 to 2600 rpm. this is my method of type 4 survival &
durability, steve jones n212kr
i almost forgot to thank greatplains for there quality parts,,without the
force 1 hub setup, it wouldn't work as well,,,
