Hi Bruce, here is my report on the findings during the weekend:
After I refitted the carby with the valve in "C", it would still no rev up. I then decided to look somewhere else, and found that the electronic module had been secured to the body with a pop rivet, this also acting as the electrical connection to ground. Pop rivets do not like high vibrations and as a result it had become loose. When taking the whole thing apart to replace the rivet with a bolt and nut, I noticed the exhaust silencer outlet blocked with oil and dirt. I removed this unit to clean it and saw the engine exhaust manifold almost completely closed with carbon deposits. Cleaned the whole thing, put it back together, and it runs again at high rpm as it used to.
Thanks again for the advice, soon I will be making my donation in order to get the manuals. Bye, Henry.
