@peesalot was spot on! Pulled all the plugs and #4 was dirty with oil.... An engine rebuild is in my future since the old 2f is tired and burning oil. Cleaned all the plugs and she's back to purring like a kitten! Thanks all!
I will do this! Thank you for the input. It wouldn't be something like my valves need adjusting, correct? Just so strange it just started running like crap yesterday after it sat for a week.
Sniper has been awesome, especially since I dialed in the timing a few months back. However, when I fired it up yesterday after it sat for a week it is running rough. Seems to hesitate and just sounds off like it is stumbling on itself. No back firing and it turns right over. All the numbers...
