I bought my S1 from a swiss specialist, but I immediately noted that the car didn't run well, despite having a horrendous fuel consumption: 16l/100km on a swiss highway with an average speed less then 100km/h!
Furthermore I noticed that unfortunately everything that was "serviced" by the specialist was more or less screwed up.
Therefore I decided to start a ground up restoration and the engine was also disassembled.
Of course the valves clearance was checked and I found that 4 of them were to tight...
Then I checked the timing and, believe it or not, the timing was at least 20° too late on the inlet and on the outlet.
Both valves were still closed at TDC with the verniers positioned on the marks that were marked originally on the Piper pulleys (!?)
I took the timing data for the VHPD from Piper's website:
To cut a long story short here is how the setting of the camshaft should be, after taking the belt apart and setting the camshafts
with a gauge...
Note: Only the inlet camshaft needed a fine adjustment of a few degrees.
This week the engine will be reassembled and then we will see if the cure was successful or not...
