My 356 4 cam is sputtering and back firing like it's not getting enough gas
My newly rebuilt 4 cam has been running great and it just started missing and back firing
and sounds like it's not getting enough gas or it got some bad gas....sounds terrible.
Modes anyone have any suggestions?
Recheck your valve settings.
Could be something simple like a blocked fuel filter, a kink in the fuel line or intermittent fuel pump?
You said it was recently rebuilt and it ran good. It could be any of Andy's suggestions, all of which are easy to check. Valve clearance is critical, and if off, it will run rough. Do your checks, maybe check to see if the plugs are fouled, plug wires are in good shape and not grounding, and check to see that the distributor is not loose, use a timing light and maybe add some fresh gas. All common checks. Good luck
