I was putting the drivegear in like you said and found the rotor was pointing to the 8 Oclock. After checking everthing I found the gear to be installed correctly. I then found the point cam and advance weights had been taken off and put back on 180 out. Took me several hours to figure it out. I think someone did this to correct having the drivegear 180 out during a previous rebuild. Thanks John DeVries

John..Mines backfiring from the exhaust and wont fire since the engine rebuild. Hopefully this is causing the problem . Thanks

Aha Ha! So that's why my distributor drive gear won't come out. I'll have to try that when I get home tonight.

Great Video. I Myself tinker around with My old 1968 VW. What you demonstrated is very much on par with setting up spark plug #1 on a VW. The firing order of an old VW is 1-4-3-2. I dont know what order MGs fire at. Also do these MGs use a Bosch Dizzy. I have removed the points from My VW dizzy and gone to electronic and have never looked back. Have you also converted MG dizzy to electronic ignition.

hi there,great vid.can you tell me how much play(if any) should there be with the distrbutor drive once its in position?. thanks mark

BEWARE! If you don't have a long enough bolt to feed the drive gear into the hole precisely, it is possible to drop the gear into the sump.

OK - I might be a tooth off. I am assuming that since the distributor turns anti-clockwise, turning the gear in the same direction would advance the timing. Presently, my timing is about 20 degrees after dead center. Anyone have a thought on this?

[@jonnda]

Has anyone managed to do this while the engine is in the car? I'm having a hard time getting all the needed tools in a useful position in order to extract the drive gear. It's a 1973 MG BGT.
