Trying to get my '53 Chev 3/4-ton running properly. It had been sitting for about 5 years. Drained the gas and replaced it. Starts, but has little power and lots of hesitation during acceleration. I pulled the plugs and all have heavy carbon deposits, although it brushed right off. Checked point gap and it is set at 16. Tried to check timing, but need a better timing light to do it. Engine had been overheating, so put in an electric cooling fan and that stopped the heating problem. Vacuum advance seems to be functioning properly. So, aside from checking the timing with a better light, what would be the most logical cause of severe hesitation and no power plus the carboned plugs? This is a 235 and it was rebuilt about 7 years ago and never has run right.
