Hello, its a glare shield not a shelf. What happened to the view...... lol

I think this is more of a fuel problem with #2 then a valve sticking issue. Question? Fuel flow is by a fuel flow transduce, right? @60 #2 EGT 1327F fuel flow 17.6 @61 #2 EGT 1124F fuel flow 15.3 If the valve was sticking I think the fuel would still be 17ish @62 #2 EGT 956F fuel flow 13.1 @63 #2 EGT 1192F fuel flow 17.1 @64 #2 EGT 1278F fuel flow 17 Back in the day when I was flowing injectors on a flow bench I would see contaminates cause the nozzle fuel stream to bounce around looking like a wild water hose spraying any old way. At some fuel pressures the stream looked good and then as the fuel pressure was increased the stream would get fuzzy and then the stream would flip wildly around. With more pressure the stream would clear up and look fine. Normally you could see the contamination in the nozzle when looking through the nozzle into a light after you blow the fuel out of the nozzle. After ultrasonically cleaning the nozzles the stream would look clean and straight through the pressure curve. I would clean the nozzles first before messing with the valve. I worked at an engine shop and I have changed maybe 10 valve springs using the "rope trick" but I don't think I ever reamed a valve guide. You would need to push the valve into the combustion chamber and fish it back out into the guild. I would also make sure ALL JPI inputs are calibrated like HP%. The JPI gives an amazing amount of information that allows you to troubleshoot in flight and on the ground but bad data could cause bad troubleshooting. I love my JPI830 and really question why I get in a piston aircraft without a engine monitor. Jim

Great Aviation Museum!!! Thanks for posting the video

I agree these are a PITA to deal with. The Eyeball vents are glued in place. That said I was able to cut the assembly and reinstall the snap ring and a small dab of locktite on the snap ring. There is not much room for other types of closable vents. I used a small Dremal cutoff wheel, repaired the vent and then used the thinest ABS I could find to reglue with a scab patch.

Hi Skip, Just to add some air race history. It is my understanding that Pete Law (Skunk works) and Dave Zeuschel first added a spray bar to the P-51 radiator scoop in 1971 Read more at https://www.airspacemag.com/flight-today/how-reno-racers-keep-their-cool-16828199/#4rY6g4xyOSQFBr5t.99 The idea was to reduce drag by making the radiator intake smaller and add ADI spray bar to lower the inlet air temp(evaporative cooling). I love this thread.....

One thing I would do before adjusting the fuel flows would be to pressure check the induction system. Its more likely that a induction hose clamp is loose and at idle you're too lean. Then verify low unmetered fuel pressure and idle mixture. jim

Hi Parker, Induction Tubes? Is that GB to LB induction upgrade?

I installed a 830 8 years ago over on the co-pilots side up high. I found it not always in my scan. This year I moved it right above the engine controls and I really like this position.

Maybe this is just the thermal expansion of the oil?

Well I fly out of a 1800ft asphalt strip and yes I retract the flaps on every landing. I think this is a small added risk, but here is how I mitigate that risk. On landing, if I am hot by +10 its a go around, if I am not on the runway by first 500ft its a go around, on touchdown I say these are the flaps and I retract the flaps. Light braking at first and harder as I slow. After I moved to this strip I graded an additional 500ft grass over run and I only used it once on a wind change on touchdown. Its speed control and I am much better now and I try to fly every landing the same with the exception of IFR approach landings to much longer runways. On takeoff, I always, use takeoff flaps, call out airspeed alive, I call out V1 (just added - thank you MSers) 80% takeoff speed by 50% runway length( I marked the runway for the mid point) I call out VR - and rotate, I call out positive rate of climb wheel up, and climb out at Vx to 800ft.

My hanger elf said only the last shot was CGI...

It’s a small world, when you own a Mooney....

+1 for Reno. I go every year and we get Box seats, B50. I have been to a lot of air shows and I crew for a private jet team. Watching pylon racing is my favorite, 50ft of the deck and wing tip to wing tip, 400mph for sport, 500mph for unlimited and Jet is 520mph. It’s the most amazing thing to watch and you can feel the speed. It’s a must to get pit passes, you can talk with the pilots and crew. Jim
