Re: Exhaust chirp

[Steve Stegmann <stegmann@domain.elided>]

Ken,

My chirping almost sounds like pinging but not quite.  Is that the same 
for you?

I have a 345 currently with Tquad in need of overhaul.  I have the close 
ratio gearbox, 3.07 gears, and 237/75 x 15 tires.  Works out to abou5t 
2300 rpm at the 65 mph I was traveling.  I was making a point of keeping 
my foot out of the carb, too.  This is critical with the Tquad.

Oh yeah,  I was using Mobil premium and had the timing static advance set 
to 15 deg BTDC, no pings at all.  I was pretty pleased with 16.4 
considering the state of the carb.

If I find out what the part number of the plugs is is I will post it.

Steve
