Reason to use distributor from aircooled T3/t25 shape combi and avoid the wbx 1.9/2.1 type-
Aircooled distributor- 23 deg centrif advance- (designed for 200deg C max head temp conditions)- add 7.5 deg initial = 30.5 deg total
Watercooled wbx distr- 28 deg centrif advance (designed for 110 deg C max temp). Wbx appicaton uses 5 deg static + 28 = 33 total.
If used in aircooled engine and set to standard 7.5 static- total will be 35.5 degs.
Obviously the wbx distr will add more performace if used on an aircooled engine while the engine has just been started and still cold. When at operating temp it will knock to pieces especially at coastal altitude because of over-advancing. At Jhb altitude one might get away because of thinner air/ 17% power loss. But still not ideal, a proper aircooled distributor advanced by 2.5 degs or whatever for 2000m altitude (and retarded back before driving to lower altitude), might still be better.
Timing advance required is affected mainly by 3 things- rpm, load, and cylinder head temperature.
All new petrol engined cars have knock sensors and also adjust timing to match engine temperature.
Knocking- (over advanced timing), = kiss of death to any engine. Like hammers hitting inside combustion chamber.

The wbx distributor could however be modified to have a similar advance curve as the aircooled type. But this is not a job for a lazy guy, lots of testing and redoing required to get this right.

If we use wbx distr on aircooled engine, to be safe we could set max total advance by strobe to 30 degs, but idle will then be at 2 degs, resulting in power loss and increase of consumption under most conditions.

Today I continued with the interior by finally fitting the shelves I bought a few months back. Unfortunately the person who sold them to me didn't mention that the passenger side shelf's brackets had all rusted or fallen off so fortunately I had a donor shelf I could use. I also had to make some brackets up.
My daughter also fitted a dream catcher to the mirror
Next up I have to redo the rear suspension as it is sitting very nose down when we drive her
Jason from German Steel Toys also sent his guys around again to fit electronic ignition. They don't usually do house calls but my bus wouldn't start due to the condenser again so he helped me out yet again. The end result is a massive difference in performance and she now starts without hesitation on the first click! Can't wait for the next road trip!

We will be traveling to Vaalplasie again on the 12th to spend the day. Will be leaving Randparkridge at around 10am if anyone would like to join us in convoy.

Adjusted the rear suspension by one click. It's a little lower than what I wanted so I may adjust front and back up a little one day. It drives, surprisingly very well though.
Nothing like driving around listening to UB40 at full blast though!
Hopefully this week the next job I will be doing is fitting the number plates and license.

Good news!! The kombi has passed roadworthy. Now a few more hoops to jump through and she will finally be in my name!

Always a good feeling when roadworthy and paperwork is done.

Funny you say that it in thinking of heading to Howick at the end of the month to collect a windsurfer from an aunt of mine. Not sure if that is wise yet.
