Austin Branson Posted April 25, 2020 Report Share Posted April 25, 2020 Greetings, oh sage ones. I hope you are all safe, free of that wretched virus, and looking forward to the end if this dreadful lockdown. In an attempt to get my engine ticking over smoothly, I have bought a 123TUNE distributor. Bluetooth for my supercharged CF. I can’t get the engine to run. The problem appears to be that at firing time, the rotor is not adjacent to a terminal in the distributor cap, but about halfway between two terminals. Has anyone else had this problem? If so, how did they address it? Many thanks, Austin Quote Link to post Share on other sites
Steves_TR6 Posted April 25, 2020 Report Share Posted April 25, 2020 Hi Austin i fitted the same distrib to my ‘normal’ tr6 a couple of years ago and its worked perfectly. perhaps you installed it a tooth out on the drive cog? steve Quote Link to post Share on other sites

The dizzy timing compared to the drive shaft is fixed by the “off-centre spit pin”. It can only be installed in one way. Waldi Quote Link to post Share on other sites

The spark is generated inside the dizzy, and the position of the drive shaft relative to the body will always be the same. Quote Link to post Share on other sites

Waldi Posted April 26, 2020 Report Share Posted April 26, 2020 I had the same issue Jochem had but on a standard dizzy. The knurled nut on the dizzy did not provide enough travel to get the rotor and lead-terminals to line up at the moment of ignition. I never understood why but Peter (from Germany) provided the answer. He built a tester himself so has a very thorough understanding of our ignition systems. Did not tell above because I thought it was not relevant. But forgot what I did to solve it exactly;) Waldi Quote Link to post Share on other sites
