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

Don’t know about the 2140, but the weak vacuum signal with the Holley 4000 not only needs a SUN machine for precise adjustment, but one with the tall manometer accessory (not many have that).  I adjusted the springs in my Loadomatic for a more aggressive curve, but also have an old aftermarket advance limiter part. Better acceleration performance, but crappy gas millage, since the limiter won’t allow the very high advance level needed for cruising economy. A centrifugal distributor and carb mod would be a much simpler solution. Or, if you have the time to waste. you could just trust to ‘trial & error’, and play with the springs until things improve (?).

Hi Daniel,
Thanks for the reply, can you suggest which centrifugal distributor I should look for?

If it is a 54 MERC, it should have the 256CI ENGINE (CLV).

Did it receive a FORD 239CI (DIF) swap at some point?
