Hello all, i recently bought an Rv-9a with 300 hours on it. Super excited but need help, and maybe you can point me to the correct thread. This plane runs hot on take off and climb. After 15 seconds from take off with a climb rate of 5-800 fpm at 5000' elevation, i go right to 420 degrees fast, if i shallow the climb to 2-300 fpm and pull power i can get it to stay under 425. My setting is almost full rich on take off but at 5000 feet field elevation, it doesnt run great full rich. It is carbureted and only producing 10 gph on take off mostly full rich. it has the Titan 0-340 in it. I understand that this engine can operate at 425 on take off and cruise, i have the same engine in my carbon cub, it just goes to that temp almost instantly. I flew it yesterday and the temp was 58 degrees outside on take off and it still went high quick. Note, this is only on 2 of the 4 cylinders. Any ideas on how to cool this beast down on take off? Maybe not enough fuel, maybe a different cowling ect.. Thanks in advance
