Lewis Ford 8N Won't Start. (Also Are Pistons Underneath Pl

Lewis Jones. · Feb 28, 2010

Hello all again. I am wondering if on A Ford 8N front mount distributor if the pistons are directly beneath the spark plugs?. Or if I pour oil down them will the oil be going to the valves and not to the pistons?. I wan't to try and increase my comression as I am having one heck of A hard time getting the Ford going. Yes all electrical, timing and posts are clean with good spark and free flowing gas from fuel to carburetor and it drains out very nicely and plentiful. But the fuel just doesn't want to up to the pistons. When I take out the new 437 plugs after cranking they are dry and I smell or taste no gasoline on them. So I am thinking the pistons rings are dry. They are not that worn as there was no large cloud of smoke last year when it was running. But it has sat A good while without cranking. So I would like to know if the pistons are directly beneath the plugs to put some oil down each piston to help lubricate them and build the compression needed to intake the fuel from carburetor.
Any help, advice, suggestions will be appriciated here. Thanks yall and God Bless.

your carb inside jets are stopped up put a little gas in maybe 2 cylinders it will hit or try to start then quickley die indicating no fuel vapor to combustion chamber

Hold your hand over the throat of the carburetor and see if if there's good suction on your hand.
If there's little suction that means you don't have very much intake manifold vacuum. You need that good vacuum to pull that atomized fuel into the combustion chamber. You will need a helper to start the engine while you hold your hand over the carburetor's throat.

If you have low compression that will affect your vacuum resulting in a no start. Rings may be stuck, worn cylinders and valves not seating or set too tight. Pour that oil down the plug holes then see what the compression is. Hal

Well, when I'm unsure of valve ring condition, I like to just pop in a compression gauge to see where I am on compression to rule out the ability to build compression and vacuum. Your post isn't completely clear what all you did to get going with your fuel system, but it sounds like you are saying you are getting good fuel to your carb but it doesn't indicate that the fuel is getting through the carb. Here's what I would do. I'd give it a small shot of ether and turn it over and see if the engine fires. If it does, I'd break the carb down and check to see if the jets are pluged. That is a common thing when one sits for any length of time.

Hello All again. JMOR. The phots really helped in my understanding. Thanks, You are one of the other regulars I know of on this site. I am wondering if you have A photo of the carburetor float?. And if you could point out like you did with the other photo's exactly what is the tang the manuals and everyone refers to?. And which way do I adjust it to make more fuel come in and which way do I adjust to restrict more more?. Also A thanks to you all. You have given me more to check up on and test.
Many Thanks and God Bless you all. Lewis Jones.

Wonderful pictures! I had a 2 cylinder Wisconsin that I couldn't get started and a good drink of oil in the spark plug holes made it start immediately. I think the more you crank on them the drier they get. Someone on this site told me when storing a Wisconsin run it at high rpm and pump oil in the intake until it quites. I wouldn't worry about a little oil getting down the intake ports, most of it should get into the cylinders. Watch out for oil when it starts, when my Wisconsin started it blew oil out the exhaust something terrible!
