Hi all, my question is why would my #1 cyl run cooler than the rest of the other cylinders? Had the carbs sycn., with the engine warmed up cyl #2,3,&4 runs about 185 to 200 degrees while #1 runs about 170. It idles ok, runs revs up ok. I have not done anything to the carbs. The cyl takes longer to warm up than the others. I have put new plugs and caps & sycn the carbs. Any suggestions or leave it be.
