I have an 0320 that I upgraded from 150 hp to 160 hp. I am running lean on climb out and seeing high temps on CHT (over 400) and EGT. (1,300 plus). Fuel flow at 90-95% power is 11gph. Lycoming manual states it should be high 12-13 gph.
I would like to drill out the jet to the next numbered drill size. I have included a photo bellow. What part number actually gets drilled out? Is it the very tip of the nozzle( 1 ) or is it part which is listed as the power jet (4) that appears to look like a gasket. Does the lower part of the nozzle come apart to expose the jet?
For those who have done this, I would love some feed back. Thanks.
