When the war started for the US, Japan was at about 80% of its maximum industrial output. The US was just coming out of the great depression and 50% of its existing factories were unused. Yamamoto knew this and warned the Emperor to no avail. The Mk14 magnetic exploder was developed just before the war but due to budget constraints only 2 live test shots were done on a target ship. One torpedo failed to explode and the other sank the ship. It was then declared ready to deploy. Sent out with a known 50% failure rate. Here began the problem; all complaints went to rear admiral Christie who was in command of the south west submarines (Australia) who also happened to have been in charge of development of the magnetic exploder. What's he gonna say? 'Yea, we sent you out with junk'? No, he refused to allow commanders to deactivate the exploders and blamed everything on the captains. Eventually admiral Kinkade became his boss and authorized deactivating the magnetic device. Later, tests using fishing nets proved the torpedoes were running an average of 8' too deep (missing ships under them). Turned out to be the device used to calibrate the running depth mechanism was itself out of calibration. Finally, after retrieving dud torpedoes fired at a cliff, it was determined that the contact exploder firing pin was too heavy and impact inertia would fracture them before they could fire the detonator.

I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
