This may be a stupid question but there are no stupid questions right? I was looking at Sixto's picture, which is excellent by the way, and was thinking.
I resealed my injection pump and reinstall it unfortunately it is too far out of time to adjust. Instead of pulling the injection pump why not pull the timing gear to make the adjustment? The injection pump has indexes on it for the timing. The timing chain can be marked easily and all it requires is pulling the vacuum pump. Please comment even if it is you are crazy.
