I have had to let my = plane set in the hangar for about 6 months due to some family problems.&nbs= p; Today I pulled it out and cranked it up with the intention of making a f= light.

I encountered several= problems.

the oil pressure was fluctuating rapidly between 20 and 70 for= quite some time after the start. Could this be just the fact that al= l the oil had drained during the shut down? I had checked the oil lev= el yesterday and it was down about a half quart, so plenty of oil. It= seemed to settle down somewhat after the plane warmed up. OAT was 68= F.
the fuel pressure was also fluctuating between the teens and 4= 5. I don=E2=80=99t know what the real pressure was but plan to try an= d check it with a mechanical gage tomorrow.
oh and the strobe quit working as well. When I turned th= e master on to check fuel level, I noticed the strobe didn=E2=80=99t work.&= nbsp; I flipped the switch a couple of times and the strobe made about 6 or= 7 strobes, then quit for good.
