Kombi Timing
fatboy - December 11th, 2003 at 08:10 PM

How often should you have to set the timing on a '72 1700 kombi ?

I am currently having to do it almost every week (~500-600 km)

This seems a lot esp as I have electronic points.

Hmmmmm..... how much is it out?????

1/2 degree???

What sort of electronics????

Do u set it by turning the crank or twiting the dizzy????

Does it ping???

Why do you reset it (duh - its out) but how do u know???

Ummm.... some thing is wrong???

Accufire points replacement

about 5 degrres out (12 instead of 7.5)

I can tell because it stops being able to idle and starts backfiring.

I set it statically using the "Jon Muir method" with a test lamp the crank set to 7.5 degrees and then rotat the dizzy until the light just comes on - always runs nice when done.

how is the bracket that holds the distributer shaft?, the one you loosen before adjusting the dizzy. Does it prevent movement of the shaft and have you tried moving the shaft when everything is finished (hard to commit to).

Not sure what you mean - the dizzy doesnt move after it is tightened up if that help ?

Very strange!
Couldn't be either the sender or pickup of the accufire moving?
Is there a gap between the sender and pick up also? They shouldn't touch.

I'll check the movement Andy.

(They aren't touching)

also make sure that rotor button is absolutley tight , have a look inside it & see if locating lug is worn / broken, if timing keeps advancing, that is weird, loose dissie, rotor button etc usually means it keeps retarding

Steve, although it does work, static timing is not the recommended method for a type IV kombi. I'm not sure that this would have anything to do with the problem you're experiencing though...

The spindle that the rotor sits on has about 5mm free play - is this normal ?

Also the rotor is worn as is the cap itself - new ones on monday methinks.

Kol:alien me2 it is very odd. - but i have never used a timing gun and wouldn't know what do with it if I had one :D

The shaft should turn fairly easily due to the mechanical advance assembly, but should spring back when released. If it doesn't, you've either lost one or both springs in the bottom of the dizzy, or it needs cleaning. This may cause the symptoms you've described.

I'll give you a quick timing light demo next time I see you. ;)
