[Vwdiesel] Hillbilly Tuning

[slatersfb at aol.com]

The automatic advance is pushed by a piston which responds to internal pump pressure. 
The manual advance lever does not reach full advance. It is only for cold starts. To advance timing fully, you would need to open the pump where the manual advance lever is mounted (two screws) and push the advance piston all the way in. Starting engine at this point would pour fuel out opening, so this is probably not a good idea. 
Also, pump internal pressure may be low due to worn parts so final advance may not be reached any ways. 
I've been trying to think of some way to check timing like on a gasser with a timing light. Maybe some kind of pressure transponder on number one injector pipe? Transponder could then trigger a strobe light to view timing marks on a crank or pump mounted degree wheel.
Any thoughts on this?

Good Question!
I have no clue how the automatic device works. But the key is to make it
go full advance.
