4.3L Carb Alpha w/ TKS Serial #: 0W615760
all temps taken using a known to be accurate no contact IR thermometer
After engine is warmed up ...
Also noticed what I believe to be excessively abnormal exhaust smoke wafting through the air (it was a calm day at the ramp today). It did seem to go away after some time passed. (picture below)
Also alarming to me but maybe normal, there was a hot spot on both starboard and port where the manifold meets the riser. Temps were at 200 F at this spot. Maybe this is OK for a small hot spot like this, I don't know. (picture below)
My greatest concern is the starboard riser is 100 F higher temp than the port.
Does any of this sound like it needs to be addressed and what would I be looking for?
Thanks in advance for help.
