Ipari Park 2038 S=F3sk=FAt, Hungary Peter Bruller +36 20 992 6034 For engine mount rubbers ' could we have price please Regards Richard From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of doug sapp Sent: 07 December 2011 01:18 Subject: Yak-List: What's new in the parts room? Fellow CJ and Yak Drivers, This will be the first "What's new in the parts room posting". This posting is designed to keep you up to date on new parts arrivals, mods and specials. It is the time of year when conditional use inspections are scheduled. You might consider our newly packaged Conditional Use Inspection Kit which contains all of the fuel gaskets, oil gaskets, compressor filter, and felt wheel seals normally changed at this inspection. It also contains a fresh desiccant refill kit. Price $54.00 per kit. New in stock: Engine Baffle pads P/N 14.36.580 (8 per set) and P/N 14.36.581 (9 per set) 400 X 150 tires (nose gear) 400 X 150 Tubes (nose gear) Rocker shaft crush washers P/N 14.07.511 285 hp engine mount rubbers P/N H2-6400-04 8 each (16 per set) M14P engine mount rubbers P/N H2-6400-04-M14P (16 per set) Exhaust valve 285 hp P/N 604.04.04 These are VERY hard to find, last shipment sold out within a week. What's NEW: Mod kit to use 285 hp shutters on M14P engine installation. Huge cost savings over Yak 18 shutters if your converting to the 360 hp M14P. Mod kit for QL-17 snot valve, stainless steel needle and hardened brass seat solves the rust problems. What's Coming: Stainless steel 3 port QSF2A flap and gear valve for both CJ6 and Yak 52 2 Week Special: Red Silicone rocker gaskets (flat type) normally $4.50 each. Special price $4.00 each Special price ends 12/19/11 or while supplies last. Best Christmas wishes from Omak, Doug and Kathleen -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

They include all new rubbers pieces, washers, bolts, nuts and cotter pins. The kit is P/N 506400KIT and sells for $475. Note that the two rubber mounts that are behind the magnetos are different from the rest of the mounts.

What the number is doesn't matter unless it is reading TIT and since none of our planes are turbocharged, you aren't going to have a TIT anyway. So the only way for EGT to be useful is if you have a way to vary the mixture. As far as I have been able to discern, there is no use for a single-probe EGT unless you know for a fact that all cylinders have been matched for mixture. If not, you need a 9-probe EGT to be of any significant use. If you are running an M14P which has automatic mixture control, there is nothing you can do with the EGT readings except maybe use them to determine that you have one fouled plug. Huosai engines have a mixture control but I found that the single-probe EGT I had was not particularly useful in setting mixture. I had more luck setting mixture by ear. My attempts to run Lean of Peak (LoP) were not successful with the Huosai because the engine would surge, probably from a poorly adjusted carburetor, most likely because the mixture would change with flow. (Overly stiff diaphragm in the carb? Not sure.) But let's say you do have an adjustable mixture, i.e. Huosai, M14P with a manual mixture modification, or Airflow Performance single-point FI. In that case you are looking for a good 9-point EGT system with either low-mass, fast-response probes (you want grounded probes with differential input to the display), or a display system that projects future EGT based on probe thermal lag response and rate-of-change of temperature. I am pretty sure that JPI fills the bill on this one. I know, you asked the time and I came back with a discussion on building an atomic clock. Sorry. The problem is, once you get it you have to be able to do something with it. Adding another gauge to the panel for something you can do nothing about is a waste of money, panel space, and your pilot workload when you are flying. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 brian@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ________________________________ Message 5 _____________________________________ Time: 08:15:30 AM PST US From: "Rico Jaeger" Subject: Re: Yak-List: EGT Actually I was asking because the plane I picked up still has all 9 probes / cabling intact and in-place, AND an open hole in the panel.
