Thanks all. Guess I'm going to try some of your suggestion today. What else can I do right now. Keep my mind off things.
Think I'll switch the plugs around first, that'll tell me a few things.
Swapped plugs now front firing and not the back. Looks like I need new plugs.
Thanks for the suggestion, Glider. Bad plug.
Two new plugs, fires now on both cylinders.
Thanks all.
