Allis Chalmers Speed Patrol First Start 4 Yrs 8 Months

Описание: What happens if a set of contacts under the magneto cover or a distributor cap are subjected to a dampened atmosphere ? Oxidation, or at least I call it oxidation. A white powdery covering that has a tendency to form on the contact surfaces. Technically that's probably not correct, but what ever it is it inhibits the electron flow to an extent none will pass. No movement of electrons in an ignition circuit equals no spark and we all know that no spark sometimes means the honeymoon is over....but in this case it means the motor is not going to start.
I find in watching videos or following a FB thread sometimes when someone inherits Grandpa's favorite tractor that hasn't ran in 5, 10 maybe 15 years the first thing they do is rebuild the carburetor and strip all the ignition components and replace everything. Points, condensor, cap, rotor, plugs, wires and coil are purchased from some Chinese manufacturer that's sold on the internet by an American company and then the fun begins. Even if they make the purchases from a reputable shop that sells quality parts....the fun still begins. What's happened is now a whole new list of variables have been added to the equation. This first thing that really should be done...considering its KNOWN to have ran fine prior to the kindly old gentleman's demise is a quick check of the fuel supply system and then to just check for a spark. No need to add all the other questions that arise with changing all the ignition parts....what's the plug gap...what the point gap....oh, by the way "How do I set the points anyway?...now just HOW were the spark plug wires routed...oh yeah, what IS the firing order....what's TDC stand for anyway?....compression stroke? How do I tell which one it is.....which cylinder is #1....why is gas running out of the carburetor....what's the float setting....how do I set the float correctly....what !? There's more than one jet in it....why is it not getting gas? I already rebuilt the whole carburetor... These questions are a sampling of ones I've read that came from an eager 'new' old tractor owner.
Ok guys, I know none of my super-cool viewers find themselves in this situation, but there are many, many others who do. This is just a sampling of the questions that arise as a result of accidentally creating a much more 'involved' re-commissioning of an old tractor by doing too much too quickly. Start with the basics....spark and fuel. If it ran ok before, there should be no issue with the timing. That brings up another point...I've seen a good number of instances where the fellows pulled the distributor then for the life of them can't get it back in time. If you are lucky the tractor you inherited has a distributor drive that stays engaged on the camshaft and the top portion of the distributor just comes off flush with the mount. Those typically are 'keyed' with an offset that will not allow installation in any way other than correct. Most are not that lucky.
The point is....when you claim your coveted inheritance from the kindest old man you ever knew, just take a few minutes and play with the old components before you replace everything and create more 'unknowns'. You may be surprised more often than not. Recently we did a 'first run' video on one that had sat for 44 years. (Link at the end of the video). In the video it looked like it was a simple startup after a magneto from a different engine was used to get it going. But what I didn't include and I really SHOULD have was that my brother actually started working on that old tractor a little at a time a year before. He had to service the gas tank and install a new sediment bowl to get the fuel system ready then he worked and worked on gutting the magneto and tinkering with it for months before finding a magneto shop in another state to send it to for a total remanufacturing. So all the old tractor 'first starts' are not smooth as silk.....but you gotta admit...44 years in a lean-to means its probably gonna need a little more TLC than Grandpa's.
Anyway...this video is about firing up this old Speed Patrol that's been sitting right outside and in the same spot since late winter/early spring 2016 or about 4 years and 10-ish months. It always was a good easy starter so when it didn't have spark a few months ago the strong suspicion of oxidation on the points was at the top of the list !! The rest...as they say....is HISTORY !!
