I just got my gearbox back in my 1973 TR6 after installing a new Fidanza aluminum flywheel and Magic Clutch Kit from TRF. Everything bolted back up - went to start the engine, but the starter isn't turning it over. I pulled the starter and tried it away from the flywheel and I can hear the motor running (can't say anything about whether the pinion gear pops out as I couldn't see it well enough). When I try to start the car (with the starter bolted up) I can hear the solenoid click followed by a hum. If I had to guess, the hum doesn't sound like the starter motor turning over - more like it's locked up, but that's just a guess. The other bit of sleuthing I did was to pull the plugs and roll the car to ensure nothing was binding. While the plugs were out, I also tried to turn the engine over with the starter - thinking that it should be much easier for the starter to perform that way but I got the same click and hum sound with the plugs out. Weird that the starter worked fine when I began this project 10-months ago.
