I stripped off the onesided covering so as to eliminate any chance of combustability. No heat comes through into the cockpit.

Make sure your fuel tanks are venting properly. 2... A 801 with a Walter LOM will drop its nose real fast an a slow final. 3... A 801 with a Walter LOM will probably excede VNE. I hope to have a bunch more info on flying characteristics of an 801 in the next couple of months. It does seem odd that ZAC leaves out simple things to get us all through the first few flights though.

So I will reset my mixtures to what they were (and the plug clour seemed fine) and take it round the pattern and pull the plugs like I've always done. The EGT's at least will pick up differences between the banks, the meter seems to do this quite well, in fact the difference of one notch on one carb needle produced a difference between the banks of nearly 200F This difference went away when I equalised the needles. Hopefully I can remember how to fly this thing after a few months of having heads rebuilt. Frank Wondering how well a 601 HDS will climb with one of Ramperformance's 137Hp EA 81's....:) -----Original Message----- From: Don Honabach [mailto:don@pcperfect.com] Subject: RE: Zenith-List: EA 81 problems --> Zenith-List message posted by: "Don Honabach" Frank, Not much of an engine person and haven't got my plane in the air yet, but you may want to take a look at www.bingcarburetor.com. They have a tuning and parts manual for the CV Bing Carb (which is what Stratus uses on the EA81), and you can also buy any of the needed parts for later overhaul, etc. for your bing carbs. In the tuning/parts manual it talks about a colortune spark plug that allows you to see the flame color of each cyclinder and adjust the carbs for the proper mixture. They also have information on carb synchronizers which may also help. Hope this helps and please let us know what you find.

I have a Stratus EA81 and a few problems.I never had an EGT before but I fitted one in each exhaust pipe because Stratus informed me that they saw signs of high cyl temps. Not exactly sure what these signs were but they thought that the motor had been "overheating". Anyway, as the water temps had never been over 220F I thought it good insurance to see what the EGT was doing. After that I had a very nice big valve job done by Ram performance...lovely properly stepped valve guides.all good stuff. So I asked Ron at Ram what the EGT's should be?...He recommended a maximum of 1250F...okey dokey...so I fit the EGT and calibrate them with a handheld EGT from work in an adjacent hole in the ex pipe. All very nice and the first thing the EGTs show is a 200F delta between the banks. I found the needle positions different in the BING altitude compensating carbs. I lift the lowest needle and the banks now read the same throughout the rev range. So life is good except that during taxi tests on our 6000ft runway I get full power EGT's of 1450F and cruise settings of 1400. I.e higher than Ron's 1250F suggested max. I decide to do a plug chop, raise rpm on the brakes to 3000rpm (engine) and cut the igniton...all I got a was sooty plugs, as if the mixture was VERY rich....I don't think it runs this rich,more like something in the way the engine takes a last gulp of fuel that gets partially burnt...besides i still have very high EGT's which would presumably mean a weak mixture! Ron suggested raising both the needles to get more fuel to cool the mixture.Now my cruise is about 4400RPM and I would think the main jet would have more authority at this engine speed than the needle. But a needle height change I CAN DO RIGHT AWAY. so I do this and taxi out to the runway....sure enough no change in the full power EGT's (flys pretty good without the cowling) 'cos the main jet is the same. So I try a few runs at cruise setting about 44 to 4500 rpm. Well the EGTs settle out to 1400F still way higher than 1250F maximum and makes me nervous because of the so called "EVIDENCE OF OVERHEATING" that Stratus told me about. The only difference is the motor was using quite a bit more fuel, about 5.5GPM compared to the 5.0 GPM it used to use. I taxi back to the hangar, pull the plugs and once again they are sooty but on one of them it was completly white underneath the soot. Now the plugs are brand new and this engine has run for less than one hour so I'm not sure plug color is a good indication of what the mixture should be for such a short stop start regime of testing...particularly if they soot up anyway when you kill the ignition. So I'm a little stumped as to what to do next? The whole premice here is that 1450F is too high, is this true from everyone elses experience? How am I supposed to get the mixture set correctly with these carbs in the first place.I always used to do this by doing plug chops on old motorclycles, but this engine seems to just soot the plugs? if it really is running way to rich, why the high EGT's? I have a hard time believing a big valve job will make a big difference in the mixture? Seems to me there must be a way to set the mixture correctly and get resaonable EGT readings. I'm pretty sure the ignition timing is close to where it should be. Any comments most gratefully received. Frank direct advertising on the Matronics Forums. advertising on the Matronics Forums.

These are both based on a 172 POH for format (and helping to decide what is needed) as well as a couple of RV POH's that I've found on line. I would be glad to share this with someone else to has similar data to swap. Perhaps the reason that ZAC doesn't supply one is that much of it is engine depenedant, many numbers need to be determined as part of flight test anyway, and the big one is that there is a fair amount of legal precedent for using the POH as a method to sue the manufacturer's "deep pockets."
