Motor dies after startup.
the vibration could be a broken engine mount in reverse? also idle to low?
the motor mounts are still pretty new. i did check those, as that seems to be the number 1 reason why a motor will shake. i looked at the mounts while the motor was on, and there didn't seem to be much vibration at the mounts.
i cleaned the rotor cap.
so i did the smell test. gas smells like it would at the pump.
also did the spark test. all six plugs have a very strong spark.
i figured, if any of the spark plugs weren't working, then if i pulled the wire, the bad plugs would be the ones that didn't produce a change in the sound. plugs 4 and 5 didn't give me any change in motor sound / vibration. maybe these are bad?
and i shocked myself. heh. i know you're not supposed to do that but i figured it was a quick and easy way to see which cylinders may or may not be firing.
i don't have a vacuum tester (perhaps i should get one) but i pulled the hose at the vacuum advance side to see if it was drawing any air (to make sure i had it hooked up to the right carb inlet). it didn't feel like anything was sucking so i moved the hose onto one that was that wasn't being used for anything.
could it be that i just have two faulty spark plugs? if it's the plugs should i just change all six?
