I have been chasing things that may be causing a lack of high-end power. I found some things in the carb linkage and carbs that I have fixed but nothing seems to have changed much on the lack of power. So, I looked at my distributor and noticed the rotor was not pointing at #1 spark plug when at TDC. I will note that the distributor was rebuilt by Advanced Distributor, and I had installed a narrow belt pulley system and as such there was no hole in the pulley. I built the motor but had a mechanic finalize some things and it was him that marked the pulley for TDC. So, after realizing that the rotor was off position I thought I would have to move the distributor a tooth over. To make sure it was at TDC I turned the pulley counter-clockwise which lined up the rotor/slot straight at spark plug #1. I am using a instruction sheet from Ottawa Valley Triumph Club and they say to have both valves on #1 closed and that could be determined by slight movement at both rockers while both on #4 are tight and won't move. When I rotated the pulley CCW I achieve this but it also seemed to do it at the marked position on the pulley. Looking at the picture showing the pulley rotated you can see the marks are way off and of course my timing would have been way off - correct? I did not pull anything other than the base so my question is: should I assume the TDC mark was incorrect and drop my distributor back in and make a new mark? Pictures are from start to where I am now. You can barely see two red dots on the pulley one for TDC and one for 8 degrees. First two pics are when red pulley mark shows TDC second two are after moving the pulley CCW. Bruce
