Stranded in Fredericksburg.

Anyone around that can help a C model owner in Fredericksburg, T82?

Won't start. Will turn over.

Is this a hot start?  Post your cell #

I'm not much help, but Mike Busch (I think) says:

In low temperatures, if it won't start, you probably under primed.
In high temperatures, if it won't start, you probably over primed.

Usually a C model doesn’t have hot start. Issues because it’s not injected.  It could get flooded though… does he have a good idea how to see if it is and how to start it?

[skykrawler]

First.....don't run the battery down.  Let it sit for 5 minutes.   Carbureted airplanes don't flood like fuel injected models.   When you pump the throttle it 'squirts' some gas into the carb throat, but its an updraft carburetor.  This is a post here that I would think would be correct:

"Assuming the engine is still warm, I do not turn on the fuel pump, or pump the throttle at all until I engage the starter.  MIxture rich, throttle position is nearly (but not quite) closed.  As soon as the propeller begins to move indicating the fuel will be sucked into the engine, I pump the throttle once.  The engine catches immediately and runs smoothly at a low idle.  Lean immediately."

If it’s flooded and it could be, Open the throttle full and go inside and drink a coke or whatever, the open carb may help the fuel evaporate,

then go back to the airplane and with the throttle full, and the mixture to cut off try to start it, if it fires and begins to run, quickly pull throttle back and go to full rich, if it dies try to restart it normally but don’t prime and or pump the throttle. It goes from flooded to lean very quickly with open throttle and mixture off of course, but that’s what your trying to do, clear the flood. It can clear the flood sometimes and not kick off, so once your pretty sure you have cleared the flood, again wait awhile to let the starter cool and try a start like posted above.

It could be vapor locked too, much less likely to vapor lock but in real hot weather its possible after shut down, like a stop to refuel.

It’s entirely possible and or likely to flood one good and wet the plugs and wet plugs are less likely to fire than dry ones, that’s one reason to wait awhile, to let the wet plugs dry out.

Also hard starting when hot is often due to fouled as in carboned up plugs, once you get home you may need to clean them.

‘You can flood a carbureted engine, and even set one on fire, they are harder to flood, but I’ve managed it.

On edit, respect the starter duty cycle, let it rest for a significant interval between cycles.

I had problems with mine flooding after shutting down for a fuel stop if I followed standard starting procedure. Now if I see that there is still fuel pressure I don't follow my normal start procedure of mixture rich, pump throttle, then start.

This is similar to what I do. However I don't go mixture rich. I have the throttle barely open with the mixture cut off. Once I engage the starter I slowly push the mixture in and it usually catches on the 3rd or 4th blade.

What kind of starter do you have and how old is it
