Re: Light-Sport Aircraft Yahoo group Climbing EGT

Hello Dave, I have a 582 on my plane, during cold weather I re-jet the carbs for the temps I'm flying in. At about 20 deg I go up 2 jet sizes on the main and the next set of needle's Remember prop loading has a lot to do with EGT. On climb out you are loading the engine thus making it run richer, less RPMs. less air to the motor,  more fuel to burn. As you level out the engine loading goes down, more RPMs, more air to the motor, less fuel to burn. I would be a little concerned if your EGTs are running more than 50 deg apart. this can be a number of things, dirty carbs, bad or loose carb socket, improper cable adjustment between the two carbs (balance), bad probes or gage. A quick check is to exchange the probe leads and see if the in-balance changes cylinders. If you are running more than 50 deg difference I would look for the reason.  Rotax says not to exceed 1200 EGT and 180 on water, Brian at LEAF tells me anything under 200 water is OK. I duct tape my radiators to keep 180 in flight, this gives me good cabin heat and does not allow super cold water to come back to the engine from the radiators. Duct tape is a cheap fix and can be easily added or taken off for the temp of a particular day. Good luck, Bob --- On Fri, 1/1/10, Dave <icgdave@yahoo.com> wrote: From: Dave <icgdave@yahoo.com> Subject: Light-Sport Aircraft Yahoo group Climbing EGT To: Sport_Aircraft@yahoogroups.com Date: Friday, January 1, 2010, 8:19 PM   looking for info on a Climbing EGT I am flying a Titan Tornado 1 with a Rotax 582 If I dont keep me engine above 5500RPMs my cabin heats doesnt function well. In order to keep during a flight today I was running at higher RPMs, I noticed that at full throttle and in level flight, one of my EGT kept climbing, I allowed it to climb to 1160, all I have to do is back off of the throttle a little bit and the EGT will drop. What would you guys suggest to look at or is this normal. I dont run at full very often other than during climb out and the EGT stays normal during this time. Thanks Dave (3M7)
