Possible .. but check carby diaphrams.. and weight sticking .. you WD40ed them? If you did then that is why they stick .. clean out the WD40 gunk and then put in a bit of engine oil .. or nothing .. don't use WD40 in there.

Ya man. How'd you know I ate mexican food for lunch yesterday?
I put it back on the table before the rage hit so it didn't get smashed to bits.

mine, one of the ears that hold it on broke off. Have a guy TIG welding it, but the TIG has to be serviced. Has anyone reverted to points?

Seems like a next step option.

From the little i've looked into it, you can't convert just the can to points.

If you don't want to endure the pain of a rebuild, in my opinion, it's easiest to just upgrade to electronic ignition.

Umm .. you already have electronic ignition .. you mean other electronic ignition. ...

A new bean can here was some $300 ,,,, but that was many many years ago .. But I think that or second hand bean can would be the easiest, simplest and probably cheaper than reverting to a points system ... (for a points system you need a bean can with points - that interfaces to the offset dirve you have, and is the right size to plug the hole in the crank case. Wires up to a new coil (the old one will blow up if driven by points) ..

I haven't checked the diaphrams yet, but they're only 8 months/15k kms old so should be OK. When i had this problem when i first put it on the road i 'serviced' the advance unit and just used a little engine oil. I only use wd40 as a cleaning agent on engine cases etc, it never goes near a mechanical component.

The problem persists... i got the new springs today and may attempt to install tomorrow ('cept there's a football grand final and bbq on which may prove too distracting).

The reason i believe it's the advance mechanism is that the revs stay high until i drop the clutch (slightly) while in gear, then the engine slows to a normal idle speed.

Status = my machinist is out of town. I need a dividing head or at least basic machine tools to match the position of the rivets for the 2nd hall sensor.

Guess I'll just replace the original hall sensor and leave it at that. No time.
Have training at Spartanburg center next weekend and 2 weeks after that is the fall old school rally.

yEEHAW- you doing their offroad training? Thats great news! Youre going to have a blast and come away with a whole basket of new skills. I remember you saying something about your co-workers' taking you out on little bikes... Great news. Remember: No one will ever tell you your elbows are too high.

haha what is that saying i like?

JUST so you guys know, that little offset driving dog is the exact same part bosch made for VW for the aircooled boxer motors, and maybe the Wasserboxer as well. HHMMMM, a modified bug distributor???

THought about this as soon as i pulled it off. Unfortunately, my centrifugal advance got sold with the car and the vacuum advance is loooooong gone.

I'd really like it if any of you had a 79-80 points advance module that you'd be willing to sell me. Anyone?

And there's the problem of 4 plugs instead of 2. You'd have to replace or swap the shafts or something with a points model or i'm not sure what that extra spark would do. Anyway... another discussion. No thread polluting Mr.

and to answer the free thinking minds question, you wouldn't use the distrbution part of the distibutor, just the points opening and closing and mechanical advance portion, figure it out and quit pontificating.

2.1 - mildly offensive, no profanity, and not nearly enough 'tude to get kicked downstairs

Lighten up Francis


BTW - to keep this on topic - the second hall sensor position doesn't have to be bang on ...just within the range of the slots

Drill it and mount it and connect it and then match mark the position

Ah well, perhaps you have to know him better to get it.

Anyway, I have heard that VW and some others have this exact same unit - like Volvo and Audi - and it's a direct swap.

The points-in-a-can can be substituted for the hall-sensor-in-a-can ignition quite easily, and I've heard that the world travelers do this for the greater reliabililty. The points are a regular VW high performance item available anywhere, but the coils may need replacing since they'd most likely fry the points after a while unless an ignition booster was added.

Since the stock electronic ignition module is just an amplifier, I'm curious if it would work properly hooked up to a points can?
