Ooopppsss I am reposting this from the Street forum, I think it is better here 😅


Hi all you Y-block lovers! I'm new to this forum from Athens, Greece with my '54 Mercury Monterey driver. It has the original 239 with low mileage, manual with Overdrive, 6volt positive ground, the 2140 Teapot and, the ' temperamental' Load-O-Matic..

Before learning that need a SUN machine, way back I tried to adjust the spring weights and really messed it up. I found one in England but it came back and still is no good. I've always had problems and lately it misfires especially in the mid RPM range.


Here are my novice questions for your kind expert consideration:

1. Is there a way I can manually tune the springs without the SUN machine?

2. Are there reliable Load-O-Matic tuners in the states I can send it for proper tuning?my Load-O-Matic for tuning or I just forget about them?
3. Should I simply forget about it and go for a point unit with centrifugal weights like the ones used in the later Y-Block engines? And frankly I would like to keep it as buy now. I ( I can easily do Ted 's vacuum Teapot conversion I read about in this forum) know it quite well
4.
5. I am also open foran HEI distributor that looks like my original and can fit with the shaft length and tang coupling to the oil pump. However there is a question with the wiring of my overdrive's kick down switch wiring on the coil, because I tried the Pertronix unit it way back and it did not work.

That's it, thank you all in advance

The LOM IGN SYSTEM required the DIST to be removed and set up on a DIST MACHINE (whether a tune-up or drive-ability concern). 

Points dwell, breaker arm tension, and advance curves were verified and corrected at that point. The DIST was re-installed and if drive-ability was still a concern, the MECHANIC/TECH would go into the fuel and advance signal system.

You can use timing tapes, an extremely sensitive vacuum gauge along with prayers and hopes until the cows come home.

There are PERTRONIX SYSTEMS that will replace the points/condenser on a 6V (POS or NEG GRD) LOM DIST. That takes care of any DUAL POINTS setup.

The points style DIST was phased out in 1974/1975 production and for good reason (IMO).

Would I personally use a LOM DIST? Not unless the car was a survivor or correct restoration.
