Hey guys I joined this sight a couple years back when i bought my truck then I kinda stoped working on it. I have a 1953 ford pickup with the original 53 flathead. Last night i put new plugs in new battery and after 3 year of no noise she fired right up. Purrs like a kitten. This motor has never been overhauled or anything smokes a little but does run. My question is when you throttle it up there is a hesitation before it reves up. It seems to run fine and higher rpms but its the first initial throttle response htat it hesitates. Any suggestions on what might cause this. Im new to these engines but learning.
