48 Chevrolet Fleetline Aero- 216 (Miles unknown) Rochester Carb Purchased approx. two years ago, sat around in my garage I was completing a light restoration (paint, chrome ETC) Drove around block and it felt fine (got up to 25mph), I recently finished the cosmetic restoration and took her on a drive, she stalled out at acceleration so I completed tune up: Cap, Rotor, Condenser, Ignition wires, Plugs, Coil, Vacuum advance on distributor, cleaned fuel lines, cleaned tank, changed fuel filters (cleaned), fuel pump, timed, carb rebuilt - checked compression last night all between 95-100 (cylinder) now: starts right up, but has a "shutter" or shake at acceleration.. she runs good at very low speeds (approx 5-10mph) She starts right up (no hesitation)
I just performed the leak test.. unfortunately no leaks.. saga continues- I did make a video if anyone would like to watch
Sounds like a rod bearing, maybe pull the pan and take a look. Possible the oil pickup screen is plugged with sludge? I wouldn't drive it or run it much until you find the source of the noise.
This may be a stupid question, but are you sure the plug wires are run right? I crossed two on my 216 and it seemed to start and run fine, but if I revved it, it would shutter and sounded like yours.
