i have a farmall 560 gas tractor that just started to miss,i put new points&condenser,cap and rotor, plugs and plugwires,on it and also rebuilt the carb. and it still misses don't know what else to do.
 
A compression check is next. The removal of one plug wire at a time (with insulated pliers) will pinpoint the cylinder that is missing. Jim
 
compression check is always first on the list on any tune up, along with valve adjustment. need to diagnose the problem first, as lots of times I have seen the old parts better than that new Chinese junk that is being pawned off. even looking at the plugs pretty much will tell which cyl. is miss fireing.
 
Ya got some decent info off the guys but also check and make sure the intake and exhaust manifold is tight . . Is it it missing on just one hole or is it missing on two holes ?? Over the years what i have found on the I H gassers are blowen head gskt. between three and four , burnt valve on the exhaust and to find that one ya either have to do a compression check or pull plug wires , woren bushings in the dist can plum drive you bat shut crazy chaseen a miss . It would also help on this to know how and when this miss all started . Use of any oil other then LOW ASH can and WILL EAT a valve so fast your head will spin . Use of to low of grade fuel can cause pistons to swell and start to seize and score the sleeve incorrect timing can also cause a miss , woren centrifugal advance can throw the timing way out of whack and can cause a miss and other problems .. Running the carb to lean can cause big problems . Using the wrong plugs can give you problems ..
