daverclasper Posted March 19, 2023 Report Share Posted March 19, 2023 (edited) Not a problem at all, though interested. A good while back my car wouldn't start. I checked fuel area first. It was getting fuel to carbs, though even with a lot of cranking, all the plugs were dry and I assumed they would be wet?. I assumed an issue with the carbs, not supplying fuel into manifold, though seemed unlikely that both carbs not behaving at the same time. As it turned out it was a points issue. So, really I should have just left the thread title as a question, though now I may as well leave my rambling on here now. Cheers, and Happy Spring Edited March 19, 2023 by daverclasper Link to comment Share on other sites More sharing options...
Unkel Kunkel Posted March 19, 2023 Report Share Posted March 19, 2023 Difficult to quantify, but they certainly do get wet and wetter from slightly glistening to there is a discernible layer of of petrol on them. In the olden days, there were priming ports on the cylinder(s),and even sometimes incorporated into the sparking plugs themselves, through which a small amount of neat petrol, say half a teaspoonful, was injected to help start up. Later, car handbooks used to warn of the consequences of running the engine with the “choke left out” as the excess petrol would wash away lubricant from the piston/cylinder walls and cause premature wear.

ahebron Posted March 20, 2023 Report Share Posted March 20, 2023 And the modern petrol doesnt seem to evaporate like the old stuff used too. Seems to be harder to get the plugs clean and working these days Link to comment Share on other sites More sharing options...
Pete Lewis Posted March 20, 2023 Report Share Posted March 20, 2023 think the biggest problem here is where manufacturers stopped glazing the ceramic insulation and the insulator is more porous. yes a non fireing engine will give a damp plug with lots of non start cranking the rich mixture has to go somewhere and it will accumulate likewise it can take a good few hot driving mies to clean the soot from the plugs after a choked start its a carburettor over fueled problem you dont now get with infection systems Pete Link to comment Share on other sites More sharing options...
