Heading to the garage now to start the install and my main, unresolved-in-my-brain question is if i need to hook up the vacuum line that is on my current stock distributor, on the 123. |

OK. BIG revelation.
Turns out my MPS appears to have gone bad somewhere along this process. I had tested it when tracking down my running-warm situation and it held vacuum fine. Meantime - just last week - I picked up an 043 MPS that I saw on ebay for a good price. Just to have as a spare - and because my 041 had been adjusted/installed previous to me. So today, I got back to timing the 123 and it just wouldn't hold a constant rpm no matter what I did. Would start, idle somewhat ok but i couldn't get it over 2000. So - on a total whim, I threw in the new 043 and it's like night and day. amazing difference. I'm pretty happy right now. I'm wondering if my 041 bought it due to one of the backfires during my initial 123. But anyway - wow. Hopefully will have this buttoned up today. |
