Stall Horn needs Adjustment

[Parker_Woodruff]

My stall horn is not going off until the airplane stalls, which is just such a convenient reminder at that point.

What's the general procedure for this, as there are recommendations not to bend the metal on the switch?

I've got my CFI checkride coming up and am taking the plane to Don Maxwell's shop to have some minor stuff worked out before then.

So far the list:

1) Adjust the stall horn.

2) Add a dimmer to the EI RPM and MP gauges.

3) Get a replacement static wick

I think Jim is correct.  Hopefully your stall warning vane/switch assy has nutplates or rivnuts AND the cross-recess on the head is not boogered up.  I'm sure Don's crew will be able to get you going.  My assy has little bitty nuts and access is nearly impossible.  Fortunately contact cleaner cured my problem and I didn't have to remove it.

Parker, what kind of fuel pressure gauge do you have?  I have original tach and MP/FP combo.  I would like to replace my tach, and I'd consider getting matching MP too but I would need to add a FP gauge.  I'm wondering what your arrangement is...

Scott, every Mooney I've flown has been different and I haven't flown one with what I've seen in the pics on your panel.  I'm not a fan of the pressure FF setup, then again you have a JPI, so fuel flow isn't an issue there.

I have the factory fuel pressure gauge up on the top left of the panel with the oil pressure, oil temperature, ammeter, L/R fuel QTY.

Down on the right side is an EI digital tach and manifold pressure indicator.  Those two were installed for just over $1000.  You can get the EI pre-programmed with your AFTT if you want.  I didn't have to do the MP, but I figured I should and wanted it to match the tach.

And FWIW, the LASAR visors are a big improvement over the factory ones.  I still need to take Charlie's takeoff checklist off the panel.

Most likely what is needed is to clean and lubricate the vane switch rather than bending it. As time goes by dirt deposits can increase the sensor force required to activate the switch. Try contact cleaner and moving the vane several times to clear the deposits.

Those LASAR visors look nice.  I have Rosens (came with the plane) that work great, and in fact the previous owner is regretting leaving them in the plane...he wants them in his new Ovation.   

The EI instruments look good as a matched set over there.  Initially I was thinking about the Horizon tach as I like the many features, but I don't like the fact it starts recording at 800 RPM, and there is no fascimile of an analog display, like the EI does with the green LED lights around the border.  I wish the EI had all of the features of the Horizon...

IIRC, the EI starts recording at more than 20 or 30 seconds above 2000 RPM, but I'm not remembering the exact figures.
