The daily rate seems a little steep if you only get to watch.

High cylinder head temp. --> Yak-List message posted by: "Cathie" Help! Recently acquired a YAK 52. It is registering a high cylinder head temperature of 200 to 205 Celsius on initial climb out and standard climb. It does level out at about 180 Celsius at cruise. This is with the gill shutters wide open on a cool day. Being new YAK owners, we are at a loss. We have been told that this is high. It is a very low time engine. We have tried richening the fuel mixture. But, with no change. Also, the aneroid altitude compensation valve. Also no change. Has anyone ever had this happen? Does anybody have any suggestions. Does anyone know who would be the best person to contact concerning this? We have heard there is someone who can bench set the carbs. Perhaps, this will have to be done. Does anyone have this persons name and/or phone number. Could this be a timing problem? Could someone advise us of the procedure for timing? We do have some manuals. The Colorado Pak has been a great help to us and we do appreciate it. This is got us stumped and a pain in the "tail". Besides, a few bugs, this has really been the only real problem we have had. We would like to expand our cry for help to the greater YAK world.

It's what convinced me to buy my YAK 52. This year I am going as owner, but since I'm on the east coast my 52 is staying here and I still be in my brother's CJ this time with a lot more front seat time, as I start to get FAST qualified. Part of the reason for events like these is to introduce pilots, to formation, and to start the learning process. The ground school is excellent and you'll get some really knowledgeable guys in your back seat. However, you do need a chute. Allen Silver is going to be there and if you give him a call maybe he can hook you up with a chute to be there when you arrive. I don't think you'll be disapointed.

Dennis Savarese" Do both the front and rear cockpit instruments read the same? 200 to 205C is normal on climb out and will not hurt your engine. 180 is pretty good for cruise. Although you say the gill shutters are wide open, make sure the cable sleeve is not sliding in the bracket just behind the shutters. Push and pull on it to make darn sure it is not sliding. A sliding cable sleeve will cause the shutters to partially close during flight. Something you'll never know until you check the cable sleeve mounting. If you want to really learn how to properly maintain your Yak 52, you should consider taking my maintenance training course. You can read about it on my web site, www.yak-52.com. We also teach you how to properly time your engine. Dennis ----- Original Message ----- From: "Cathie" Subject: Yak-List: HELP!

Paint your CHT gauge with the limits of yellow (100 to 130), green (130 to 185) and yellow again on the top end (185 to 225). I never run anywhere near the top end of 225 and I'm in the Mojave Desert...... So if you're below 225 it's all good. If you're still worried about high cyl temps per American standards then just change your oil regularly and run an upper cylinder lubricant like MMO :) Frank N9110M YAK-52 L71 -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of Cathie Subject: Yak-List: HELP!

High cylinder head temp. --> Yak-List message posted by: "Roger Doc Kemp" What pitch angle for climb (12 deg) and airspeed (160-170 kil/hr -about 103 mph) are you climbing out at? Also what % rpm and manifold pressure (advance for the Russian purist) are you climbing out using. Truthfully, 200 deg C is not a temp I worry about for a short time. It is normal to see that temp on climb out. The Russian manual states you can operate the engine for up to 10 min at 275 deg C (actually up to 15 min). Not that I want to see that but can if the shutters close on you while climbing out because the friction lever is not set tight enough. Do you have a YAK-52 handbook? If not go to www.flyredstar.com and order one. Can also download the checklist from www.yak-52.com. I will be happy to mail you a copy of mine also. Mine is in kilometers/hr but the conversion is easy. Doc > [Original Message] > From: Cathie > To: > Date: 5/6/2005 6:57:45 PM > Subject: Yak-List: HELP!
