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

A lot of excellent information and a lot of choices in all the above. You did state the distributor was sent out to someone who had a Sun machine which produced no favorable results. Maybe?? the distributor isn't the issue. I noticed the vehicle has vacuum operated power brakes along with the usual vacuum lines for the wiper system and the heater control valve. Have you tried temporarily blocking/plugging all those vacuum lines to see if a vacuum leak might be a contributing factor? The spark plug wires are the early carbon "Sipcon" wires that were like most all early carbon wires, not very reliable, even in the day.  Coil, condenser and points?  Also, if I needed to set up a Load-O-Matic and didn't have a distributor machine, I would try using a vacuum gauge and a hand operated vacuum pump plumbed to the vacuum diaphragm. It would be a pain but with a timing light you might get a good idea of how the distributor is functioning.  Just my 2cents, welcome to the site and good luck....                     Very nice Mercury - when able, share some more pics of the car.
