710 gone crazy?

710 gone crazy?
Went to go start and drive the Rex today. Haven't driven it in about a week, so you know I miss it. Roll it out the garage, and fire her up.
Fire her up.
Fire her up.
Flood her.
DOH! So, I grab my 13/16 wrench and pull the plugs. Soaked, so I grab my torch and burn everything off the plugs, and in the plug holes. Fire makes me happy. Turn the motor over without the plugs, and greeted by a nice fog. It starts to clear up after 10 seconds, and I fire up the spark plug holes again. Plugs in, wires in, and begin to crank it.
Crank it.
Crank it.
Fires! but very very low idle, my tach isn't even moving. Also sounds like its running one rotor too. Hit the gas a few times, and she is golden. Then I look at my oil pressure... Idling at 65psi? I am running 10w30 right now, Royal Purple. I figure since it is cooler outside than usual (it is a mild 75 here) the oil would be thicker and when it warms up, all should be well. Well, car gets warmed up, and now my 1000rpm idle is pushing about 50-55lbs of pressure. Thats not right. I know I usually sit around 20-25psi when I idle. Go driving around and notice that at full pressure, it is pushing 85-90! A part of me is like oh crap, another part is excited at the higher oil pressure.
Get home, and look at my lines. Nothing kinked to the gauge (mechanical gauge, and I would think that a kinked line would show lower pressure?), nothing out of the ordinary. I know she drops about 3 or 4 drops of oil after I shut her down from the lower banjo bolt on the oil cooler. Nothing has given me problems before.
I will start her up again in a few hours, when she is nice and cool and see if it is still doing the same. Also, the oil has maybe 2200 miles on it. Almost time to change it!
PS - Running premix
What do you think could be causing my higher oil pressure?

My FB is pushing 50+ at idle as well. E's FC does as well. Hers started registering that when I switched in a new Oil pressure sender. I am cleaning mine in the FD sometime soon and will report my changes. As mine is now at 20 in the FD at isle (1k)

You let it sit to long and then flooding it caused it to lose compression until you got it going a bit. I used to experience this every spring up in Pittsburgh when I rolled the 7 out from the garage for the season. Its normal. It would sputter and run on one rotor until the other one finally started sealing. Old engines do that.
Don't know about the oil pressure, maybe something gummed up and it needs to get real hot to bust it loose. Those pressures don't sound that bad but the difference from before means somethings changed. Hopefully for the better.
Heh, maybe that bridge will happen that much sooner
