Title: timing
Post by: dwdwdw on September 12, 2007, 05:58:12 PM

I am trying to set the points gap on a villiers 2 stroke engine, I am trying to use the good old bulb & battery method. when I connect to either side of the points the bulb lights up. problem is it stays alight! it gets dimmer when points open. I thought the idea was that when the points open no contact would be made & the bulb would go out. I have fitted a new coil & cleaned off excess oil that might be causing conduction from the mica insulating plates. anyone out there got any ideas as to why bulb stays alight. regards Dave

Did you disconnect the ignition condenser/capacitor?

when I disconnect the coil/condenser (soldered together) the bulb goes out when gap opens I have been told the magento coil allows current through hence the bulb always being on & getting dimmer when points open, as I have only tried this method on magentoless triumphs I was foxed by the continuosly on bulb. many thanks for your help, best regards Dave
