giving the experts a chance

1st June, 2006 by Jonathan

Haven’t been entirely happy with Midgie’s performance. She sometimes struggle to idle (could be points gap too big), she sometimes misses at full speed under load (could be points gap too small) and she pinks (timing?). I have therefore decided that points are a pain in the proverbial, as setting them was plain fiddly, and every time they change the timing has to be done. I just don’t feel confident enough to tackle tuning and timing, so I am taking the easy way out.

I took Midgie to visit Bill Reeves at the MG Centre, where he fitted the Lumenition Magnetronic alternative to points and then balanced, tuned and timed the whole lot. Apparently she was only really running on one carb and the disi took 2 hours to un-sieze! I have a couple of things still to check, as she’s still not happy at motorway speed, but this is what was done:

  1. Remove Distributor and fit Lumenition module, connect wiring to non ballasted supply
  2. Adjust timing to 10 deg BTDC.
  3. Remove Air filters, check carburettor mixture and balance – adjust as necessary.

Total… £1,207.66
