From: mr.gsun@gmail.com

RV-List,

I've had issues with overheating on my 2004 RV7, IO 360 with about 560
hours.  I had the cowl off for other reasons and did the "coke bottle test"
and measured the fuel coming out of the injectors with just the electric
boost pump on and the mixure & throttle full in.

At 28 psi as registered on my Skyview system, I got:
#1 110 ml in one minute
#2 115 ml in one minute
#3 108 ml in one minute
#4 112 ml in one minute

I had cleaned the injectors by soaking them in Hoppe's cleaner as per
Lycoming instructions less than 8 months ago and the spray pattern was
identical in all four.
So I swapped #3 (the lowest) for #2 (the highest) thinking that if I ran
the overheating cylinder a bit richer, my problem would be solved.  I
soaked them again, inspected and dried them before installation.

Does this seem reasonable?

do not archive
