Some people can tear up a crowbar in a sandpile.To start a diesel thats in good shape with hot batteries crank it over about like you would start it usually then stop and wait about a minute,then the second time it usually will start without ether because the compression heats up the combustion chambers and it fires the diesel way better than cold steel in the combustion chamber.You want to try that a couple of times before you even hit the ether injector if it has one.If you use ether right it can start your engine.Just a sniff with the air cleaner out while its cranking is usually enough.I have many times fired my truck up by myself by giving it a shot which is about a one second shot or less directly with the air cleaner out,then cranking it after I got in the cab.The colder it gets the harder it is to get it fired up the first time because the ether looses its potency when you walk around to crank the engine over,second time will usually get it going.However its not good to keep squirting ether in if it doesnt start.Like those ether injectors only squirt a measured amount.You dont want to squirt any more than that which is about a one second burst.If you have help cranking it and even a smaller shot than one second will usually fire an engine in good shape.I have started a gas engine with ether but not very many times.You dont want to just shoot ether wildly into the carburetor of anything.Preferably with somebody cranking shoot a sniff at the carburetor.Thats usually all it takes to fire a good engine.If that wont fire it you arent going to get it running probably and if you use a bunch of ether you can lock the motor and burn up the starter maybe blow the head gasket and break head bolts.Ether has always been a last resort on a gas engine for me.If its getting gas you ought to be able to get it started without ether by using the choke.If the motor is wore out and the choke wont start it,maybe ether will if you are lucky.Two things also work besides ether.Wait for a warmer day,and pull it with something that runs if it doesnt have an automatic transmission or is froze because it has water in it.I dont know about brake cleaner,never tried it.
Also where it dries out the cylinders,it doesnt have to wash the cylinders down,it can burn all the combustable stuff out of a cylinder because it is a volitile explosion in there and dries out the cylinder,then it has less compression.Ive seen it happen before and took plugs out and squirted oil in the cylinders and got it running.Motors with a lot of wear might start good on a warm day but not even think about it when its cold.Just by not cranking it as fast as when its warm,or when its warm the pistons fit better and have a little more compression,or whatever.Then you burn that film off of the walls of the cylinder with volatile ether and it has less compression,wont start until you squirt oil in it.
