The cowling is final back from the paint shop. =C2-He does good work; he's just slower than molasses. =C2-His specialty is custom cars and hot rods so he's always backed up on those. =C2- Regarding the carb heat test: =C2-I may have mentioned on here that the st ock set-up with a PowerFlow didn't pass the carb heat test. =C2-The way th e test is run, if it's hot outside, it's damn hard to pass the test. =C2-I missed it by 4 degrees. =C2-I'm hoping for 30 degree air. =C2-Then I on ly have to do one test. =C2-You see, even though I didn't change anything in the path, since the carb heat source is 'inside' the cowling, the FAA see s it as affecting carb heat. =C2-I need to get a 90 degree temperature ris e out of it. =C2-On the stock cowling, I missed it by 4 degrees. =C2-By- the-way, I did find a couple of cold air leaks. =C2-Fixed those. =C2- I'm going to install the first production cowling today. =C2-I need to cre ate the installation procedure of the cam locks as I go. =C2-That should b e fun. =C2-Cross your fingers that I don't have a Grumman fly in on an eme rgency. =C2- Also, I've been fixing fuel leaks in a 2-seater. =C2-I hate those things. =C2- ________________________________________________________________________ aol.com ________________________________ Message 2 _____________________________________ Time: 02:19:51 PM PST US From: Bruce Smith Subject: Re: TeamGrumman-List: Cowling update Gary, OK, I'm not the smartest person in the world, but wasn't the carb heat source inside the cowl for the original cowling? Why would your new cowl, which has better airflow through it, cause a difference that would make the FAA go bonkers? It seems as though every obstacle you overcome, they throw up a new one.
