Help Needed--Update on my Stalling Problem--Still Got It

[yiterp]

as everyone probally saw in a earlier post i made i have been having a stalling problem with my wing--will i thought it was vapor lock and felt good with everything and today at work i let it warm up more than normal ro 4 bars--this is the point were the stalling usually happens and sure as can be the same thing again but i was still in the parking lot so this was a good thing.
well when it happened this time the new volt meter i installed let me see a little more what was going on--when first started the volts were normal but after awhile they went sorta crazy--dropping to 10 up to 12 or so then back to normal--checked voltage at battery--12.9 volts--when brakes first applied volt drop to 10 for a split second that back to normal--got it started and it seddled down but the voltage is still a little weird--drove home no problem--radio going-rear lights on--no problems--checked battery again at home and it is at 12.7 volts--after looking at my gauge it looks like the heat warped the needle a little bit--but it is still operating ok i think
do you all think this is a voltage regular problem--seems like it to me or am i wrong

the more i checked out the volt meter--the heat warped the hand to the left so i was getting a low false reading--but man what is causing my problem--getting really tired of it--on the verge of selling the wing

I haven't been folowing your post. One thing I would check if you haven't already is the coil(s). They can short when hot.

Just had a thought, did you have any of these problems before installing the volt meter? If not, and considering the needle is warped I wonder if the meter is interfering somehow?

[yiterp]

yep still had the problem--was hopeing the meter would tell me more of what was happening

When it stalls, have you pulled a plug wire to see if it's getting fire or not? At least this would narrow the problem down to either fuel or ignition.
