The condenser serves as a spring pad and a reserve tank for the electricity to stop and reverse If this reserve weren t there i e no condenser there would be a spark jumping at the contact points and the secondary voltage at the spark plug would be much lower and point life would be very short But the condenser contains the electricity s jumping tendency and enables it to reverse direction like a hard ball hitting a rubber wall and bouncing back This bouncing goes on for several reversing cycles range about 3 to 10 cycles This creates an alternating current and voltage in the coil so it can be a transformer Eventually the resistance in the windings dissipate the flow and the high voltage spark ends However this spark time extension does play an important role in assuring mixture firing under a wide variety of temperature load and mixture conditions lean to rich SOME WISDOM amp WIT from Tom amp Paul QUESTION MODEL G VALVE AUXILIARY SPRING STRENGTH Do you know a source for auxiliary valve springs on the 06 G One of mine is stronger than the other three and I d like to even them up Also do you have a figure for the correct strength for both the auxiliary and intake exhaust valve springs is ANSWER These are tough little buggers there is no spec for them and they frequently get overheated and lose tension So I don t know Since valve opening and closing is not critical on these it may not matter
