Could cause an explosion, don'tchaknow?


True, using starting fluid with een one glow pug working can cause a
powerful ,pre-detonation which could crack a head, and or blow a head
gasket, or even worse, bend a connecting rod. Not only so, but every
time the starting fluid detonates, it puts tiny "ping" pockets on the
piston top. Eventually on a tear-down, it looks like somebody was
beating on top of the pistons with a hammer and a punch!

If necessary....A safer alternate to using starting fluid, that is,
if you can get past the air cleaner , is to spray penetrating oil
right to the throat of the manifold while cranking the engine. , it
won't start right off, but it's much safer on the engine, plus it will
lubricate the cyl. walls at the same time. Starting fluid drys the
walls off, and over a prolonged use will help wear out the rings.
