Hmmmm, you would think so but if it is running strong and accelerating like the wind then I guess it's normal then. Maybe the rear cylinders are overheating like the cooling system needs flushing. Are you feeling the motor or the exhaust pipes??

Yes all 4 cyl should be same (close)temp. If you have only suddenly noticed this there is a good chance the pilot jets on the offending(cold) cyls have been plugged from bad gas/varnish. Try synching the carbs first, if they won't synch properly then all 4 need be cleaned/rebuilt
