Cant seem to get the static and timing gun to match

I have a 1966 beetle with a stock dizzy and static time the car to 7.5 degrees. But when I hit it with the timing light, it shows 20 degrees on the pulley, instead of 7.5. Any ideas wy this is happening? Thanks

20 degrees at idle?

Are you disconnecting the vacuum hose when checking with the timing light? The spring inside the dizzy may be worn.

From http://www.oldvolkshome.com/ignition.htm "Beetle 1966-1967 - 7.5deg BTDC Static or @ 800-950rpm w/strobe w/vacuum hose disconnected and plugged
Advance/Retard Range: Vacuum (Advance Only): 17-19deg @ 1.3 In. Hg, 24-28deg @ 3.2 In. Hg".

yes I did disconnect the hose... I dont get it... it seems to be running and idleing right based off the static timong... do I have to use a gun

I would stick with the static timing if it is running good. Your timing light may be off (weak pick-up signal). Is it steady at 20 or does it wander ..my be a worn dizzy shaft.

yes it was clipped on wire # 1, it is 12 volts and read 20 degrees at idle... I dont get it... It is a cheap 12 dollar light ... I wonder if that is what the problem is?

I would blame the cheapy gun. Even the higher priced timing lights will be off a bit, most state on the packaging or in the manual of a +/- 3* accuracy .Stick with the static timing since it's a vacuum advanced only dizzy and it's running good. I have a 65 Beetle with the same type dizzy (vacuum only) and I static time it.

Just so you know, If you have a 6 volt system you can use a 12 volt timing light on it. Just hook up the 12 volt timing light to a 12 volt battery from another car. Works just fine!
