And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
There are some things you can only do running. Think about the complexities of radial engines with pressure carbs and dual magnetos and no faut codes. You just gotta figure it out.
I'm pretty sure they're looking for an oil leak. There is nothing that can be adjusted while an 1830 is running. Idle speed is adjusted using the throttle and mixture control in the cockpit (too rich and you'll foul the plugs, too lean and your engine will suffer from pre-ignition so watch the cylinder head temp gauge) and timing a round engine cannot be done with it running. Besides the obvious safety concerns, there are no timing marks on an engine with a reduction gearbox. While all the spark plugs are removed, you insert a Time-Rite indicator in #1 cylinder spark plug hole and attach a buzz-box to the magnetoes. As you turn the prop slowly by hand your helper watches the lights on the buzz-box, as the points on each magneto open the corresponding light goes out. Adjust the magnetoes as necessary until both lights go out at the correct number of degrees BTDC. Al_in_Ottawa
I wonder if that engine noise was any louder than some of the young turds who blast their car radios so loud that you can hear them a mile away with their windows rolled up?

ReplyDeleteBuilt In Test and fault codes are wrong more than right.

looks like there is a set of legs on the other side of that engine.
ReplyDeleteThere's two of them working on it.

ReplyDeletePBY - Catalina. What an amazing and heroic plane.
ReplyDeleteCan you imagine the noise?

DeleteDon't think I'd want to be making that board wiggle too much and swing forward into that propeller...
