My SV has always been hard to start; yesterday it just refused. Wires are new, spark plugs have less than 100 miles on them and are a light tan. Head gasket new, valves adjusted and rechecked. Pertronix Distributor and an internally ballasted Coil. Weber 32/36, manual choke. Timing correct according to my timing light. New gas, electric pump that works and clear filter. Now, the pistons I recently found out are flat top which apparently are not stock. I just replaced the PCV valve and the car started then and ran very well It was cold yesterday and the car gets worse the colder it gets. I run the recommended spark plugs and use NGK.
I once heard a mechanic tell a customer that if there is spark and on time plus getting gas it has to start.
There is no way these cars could have been sold being this hard to start. Something is off; is it that pistons? Flat top with unmodified head would mean high compression but mine is 150ish across the board WOT tested.
Am thinking of going one heat range hotter on the plugs, Since I do no freeway driving and no long distance driving, it seems the burnt piston risk might be small.
Please, any thoughts?
