Spark doesn't usually get better as the engine warms up but..........
The rest of that is an excellent suggestion that I have been meaning to mention but the tired old brain somehow lost track of.......
Given the symptoms, any shop with even marginal competence should have checked all that while they had it, hence the suggestion to find another shop.
Master Mechanic Alan should be able to check the plug on the tube himself; the other stuff.......maybe not. :biggrin:
