  1. Problem solved thanks to this and it was an easy fit. Thanks again for pointing me in that direction!
  2. I recently had a new GI 275 configured as an engine instrument. When it was first installed the manifold pressure rapidly fluctuated +/- 2.5 so much so that you had no idea what it was reading. The old gage was rock solid but I was beginning to strongly suspect that it was reading low. I'm speaking a little beyond my technical knowledge but as my mechanic added something onto the line to limit the size of the pressure line which helped bring it down to +/- 1. Later I think he said he pinched a bit of the line a small amount with a pair of pliers which helped a little more however, still, once I apply any decent amount of power it fluctuates about +/- .7. Can anyone explain in layman's terms what we need to do to get it down to a usable level?
  3. I suppose I could consult the parts manual but to save time can anyone tell me if there is supposed to be a sleeve over the track of the baggage door? When I got my plane back from annual the baggage door will not stay open because the inside metal arm with the tab on it doesn't stay within the track. FYI - the weight of the door closing from full and contacting your head really hurts.
  4. The Brittain PC in my M20C went a couple years ago and although it might be serviceable I am considering upgrading to something a little bit more elaborate that will hold an altitude and course. Searching here I've seen the odd post about a couple companies getting close to providing something but, perhaps in laziness, I am looking for a list of my options including all of the equipment one would need.
  5. I recently did the same thing with the same model cap. I found a used replacement on the internet by looking for the part number. Luckily a couple of different aircraft use the same part. I have one spare now.
  6. Thanks for all the responses. To confuse matters I checked it with engine off and it actually under-reads what the pressure was by 1 1/2". My mechanic suggested that he could have it calibrated or that I just play around with different settings over the summer (while keeping an eye glued to the cht's) and keep records so I can find settings my airplane like.
  7. Thanks for the hint, I will definitely check on that at startup next time.
  8. I use an external gauge to set RPM and I have no reason to believe that it is inaccurate; it gets the same readings as my mechanics. I will have to check the manifold pressure reading with engine off next time I'm at the plane. I have a EI ubg-16 but it's not hooked up for fuel flow or MP unfortunately.
  9. I started to keep some more detailed stats to see how not even close to the book numbers I am getting. Depending on altitude I typically setup for closest settings under 75%bhp and lean. Usually I am 15 or more mph short of the known unrealistic POH figures. I just started keeping fuel statistics though and I am running at 7-8 gph, certainly way better than the books range of 9 - 9.4. I have a portable tach that gets the actual RPM, leaving either I'm leaning waaaaay too much (which I don't think I am) or the MP gauge is off by an 1 - 1 1/2 ". Does anyone know if this is likely? Would my mechanic be able to verify the meter similar to the tach?
  10. Merci / Thank you Yves. Looks like Ill be back in business quick.
  11. Lol thanks I am a bit of a gambler but "$100 untested and uninspected" a win wouldn't feel like much of a win and as for a loss ....
  12. Thanks. Before I posted I searched solenoid and came up with some information which wasn't specific enough for my lack of experience. A discussion that resolved to "Skytec metal can ones" and https://www.mcmaster.com/#solenoids/=16scf3q.
  13. My M20C has decided she loves me so much she doesn't want me to leave her alone so she leaves her electrics on after I shut off the master to keep me around. With a little help from my mechanic I suspect it's the solenoid. The parts manual lists the solenoid as part number 001464 which I cant seem to source from anywhere. Does anyone have the part number of a suitable replacement? Thanks! Dave.
  14. Awesome, thanks. I'll let you know if I need to take you up on that offer in the next day or two.
  15. Thanks for the great advice and giving us something to chase. $0.25 ... that's probably $0.32 Canadian.
  16. I only assumed it was, but I suppose I really don't know. I will check for any markings if I get a chance later today.
  17. i suppose I could do that, just doesn't make sense that it works fine when not needed; that's why mechanic was questioning its placement.
  18. It worked in boiling water, it worked when shorted out, it doesn't work plugged into the engine. Consider it works in theory, just not in practice.
  19. Since purchase my oil temp gauge doesn't work. We pulled out the sensor, shorted it and it registered. We dipped it in boiling water and it read approx 232. I do have an engine analyzer that has a working oil temp gauge but I'd like to have the quick visual (besides the analyzer is only really supposed to be a secondary). Does anyone have any thoughts? I've attached a picture of where the probe is. Dave
  20. Great idea, thanks for it. I will remember next time.
  21. Noted .... I have a 50 point something megapixel camera and plenty of very fine glass to go with it ... this is the best I could come up :S.
  22. Ahhh, thank you, I believe that solved the mystery. I also left the wing covers on.
