Brian Tyree 11-29-2012 14:48:37 68.35.184.21 Report to Moderator	I am having a problem with my 1953 Model 50 that is driving me nuts! Help. The tractor sat for years and the motor was stuck. I pulled the head and got the cylinder unstuck, put it back together and got it running. The problem, It runs on the right cylinder. the left is not firing at all until I unplug the right cylinder and then it starts running on the left. It will even start on the left if I have the right plug wire off the plug. The minute I reattach the right plug wire the left stops firing. This tractor has a distributor.When I put a inductive timing light on either cylinder it seems like it is firing. It seems like it will run on either side, but only one cylinder at a time. thanks Brian [Reply]   [No Email]

Getting suspicious of something as previously stated such as a rusted through manifold, blown intake gasket, sticking valve, wrong valve lash and most likely a dirty carb.what is the compression?   [Reply]  [No Email]

I have given up for the time being. I think the tractor will become yard art and I will just use my 1940 Model A.   [Reply]  [No Email]

Possibly some weird arcing goin on in the cap. Or as stated earlier a carb issue. Those carbs can be problematic if they sat around and can take 2 or 3 cleanings and alot of patience. Don't get me wrong they are a pretty simple carb.   [Reply]  [No Email]

When I talk about the left side, it is the flywheel side. Also I know when it is actually firing or not. The cylinder does not get even a little hot. The right side gets normally hot, burn your fingers hot. When I pull the right plug wire it starts running on the left and the cylinder gets hot quite quickly. Either side will run with out the other. It even idles quite well. The right seems to run a little better.   [Reply]  [No Email]

Right being the pulley side. The reason I ask this is you normally never hear the right side hit/fire at an idle until a load is applied or a plug wire is removed. Will it miss under load as well? If you have not replaced both plug wires do so. If by chance a plug wire had an open, spark may take the path of least resistance and jump in cap creating a confusing situation. Would be pretty confident problem is not coil, condenser, or points.   [Reply]  [No Email]

It was handy. Nothing has changed. I swapped the distributor cap from my model A. I haven't tried the rotor yet, but will do that. It still runs nicely on the right cylinder and is not running on the left until I take the right plug wire off. Then it will run on the left. It has the 2 barrel carb. and a delco distributor. This tractor may yet become yard art!   [Reply]  [No Email]

Have had them do some funny things over the years. Good luck   [Reply]  [No Email]

Check the points gap on BOTH high cams and insure theres no distributor shaft wobble Id run it in the pitch dark to look for tell tell arcing like plug wires etc Got another set of wires you might try, maybe its a plug wire problem (arcing may show up easier in the dark). On the vacuum leak the other gents mentioned with her idling spray carb cleaner or WD 40 etc all around the manifold base and carb to manifold junction and around the carb to see if it makes it smooth out and/or speed up, if so you found a vacuum leak leaning her out John T   [Reply]  [No Email]

It has a newer coil on it now, one made to run without a resister. I will go to a straight 12 volt coil. It is a Delco distributor.   [Reply]  [No Email]

Time to squirt some oil around the base of the manifold and see if it improves.   [Reply]  [No Email]

How's the cap? Are the points opening equally on each cyl. ? Is the timing correct? As you already know, makes NO sense. HTH   [Reply]  [No Email]
