Looking for 4S Hot Glow Plug
Looking for a 4 stroke "hot" plug but cannot find one?
Also my 4 stroke magnums seem to run better, idle better with hot plugs. Do 4 strokes like hot plugs better than medium or is it "cool" plugs?
My issue is idle in an inverted 4 stroke and I read at the bottom hotter is better in this case?
Found this.. seems most helpful
