Title: Grey motor dwell angle Post by: Newby13 on January 02, 2023, 07:01:07 PM I am just setting up a grey motor I have rebuilt and was wondering if anyone knows what dwell angle should be on it using the original Bosch Dissy or do I just set the gap and leave it.
Also I am chasing a vacuum advance diaphragm as mine just don't work thanks all. John Newbound Title: Re: Grey motor dwell angle Post by: ardiesse on January 02, 2023, 08:27:52 PM 36-41 degrees. But just set the point gap anywhere between 0.012"-0.016".
There's a bloke in Queensland who sells rebuilt vacuum advance units. He should be Googlable. Rob Title: Re: Grey motor dwell angle Post by: Newby13 on January 03, 2023, 07:34:45 AM Thanks Rob I'll try to find him
Title: Re: Grey motor dwell angle Post by: Newby13 on January 03, 2023, 07:46:57 AM I found that Rare Spares have them for $21 The guy in WA wants over $100 for a rebuild and I have to send him a changeover unit
Title: Re: Grey motor dwell angle Post by: ardiesse on January 17, 2023, 11:53:32 AM . . . except that the Rare Spares units look like they're for red/blue/black motor Bosch distributors. They won't fit a grey distributor.

Title: Re: Grey motor dwell angle Post by: ardiesse on January 18, 2023, 07:58:32 PM Don't know about Accuspark, but I can recommend the Pertronix ignition module, with the following warnings -
Your distributor needs to be in excellent condition (centrifugal advance working, with no wear in the parts; no end float in the shaft; vacuum advance working, and ground braid in good condition) before you install the module. The magnet sleeve is difficult to install over the distributor cam. You need to grind a small amount of material off the vacuum advance pull rod anchor bracket to clear the magnet sleeve. Rob |
