i replaced spark plugs and wires , vacum advance, fuel pump and still wont
run right. when it sits at an idle is runs ok but when you give it just a
lil bit of gas the motor starts to miss the more gas you give it the
worse it gets.i looked in the carb. when i play the throttle and both jets
are spittin gas just like its brand new so i know its gettin gas. i
checked all the vacum hoses and there all good... please any ideas?
Double check your plug wires.
I had similar symptoms when I inadvertently swapped a couple of wires on
a SB Chevy.
Driver side of engine is 1357
Passenger side is 2468
I had this problem on a 216. Make sure that your points are gapped
If that's not it, then here's what else I'd check:
Valves (if a valve is bad or stuck, you don't get compression, and that
cylinder will miss)
If it's not any of those, then I've got nothing.
