JohnDeereJosh, that running on one cylinder is somewhat normal on the single barrel carbed Deere 2-cylinder tractors.. It should pick up & run on two cylinders when a load is applied.. Those Deere 2-cylinder tractors have a 180�-540� firing order that allows the #1 [L/H cylinder] to receive most of the fuel air mixture at low RPM�s & idle conditions.. That�s why they call them Popping Johnnies [they kind of miss on one cylinder while under low/ or no load].. Try shorting the L/H cylinder with it running at idle & see if it runs on the R/H cylinder, if so it�s probably normal.. If the R/H cylinder still misses under a load you have an actual problem like carb problem, or low cylinder compression, or worn camshaft, or loose valve guides, or weak spark, or ??? You might try pulling the mag then reversing it by 180�, then swapping the plug wires in the mag cap [assumes a Wico C or X mag].. That will allow the mag to fire the opposite cylinder it is firing now.. If the R/H cylinder is still weak you DON�T then have an ignition problem.. Sometimes running too much initial ign timing advance can make the idle & low RPM cylinder power discrepancy worse so try retarding the timing slightly to see if that helps.. Other things to check if your problem is also under a load� *Check the valve spring pressure on the bad side [a weak valve spring can give cranking compression but not allow a good firing cylinder] *Check the back of the intake & exhaust valve for coking [I have seen valves so coked up that they almost completely choke off the air flow] *check the cam bearings [bushing] for wear as a loose cam can really effect the engine performance on one side vs. the other side.. *Try adjusting the carb�s idle needle.. Sometimes a slightly richer mixture can allow the R/H side to pull more of the idle load.. If your tractor has a low power R/H cylinder while pulling a load post back as you then do have a problem & need to address that.. [email protected]
