hello my friends, I have been trying to get my 58, 420 running for a while now, I just tore down the carb for the third time and rebuilt it. new float, needle & seat, bushings, seals, etc. put it back on, fired it up, she ran like a dream for 5 minutes, then as the temp was nearing the thermostat op...

thanks greg. I will ck the timing, that's one thing that has not been done yet. I figured it must be close, just the way it started cold, not even a full engine revolution & pop she is running. it is very strange how it can run sooo great for 15 minutes and then fall on its face and die, that's what...

Ok, good to know, thanks lavoy.
Happy new year to you all & go seahawks!

I researched it and found out that I do have a 12 volt single wire G.M. style alt.
and because I don't have any accessories, such as lights, etc. I shouldn't need a regulator.

next step will be to clean up the wiring

thank you for your help, and have a happy new year!

howdy all, my 58 420 was converted to 12 volt b4 I purchased it, the 6 volt amp meter was left in it & hooked up to the regulator, wich I think is original & 6 volt also. so when I put new gauges in it, mechanical temp, oil pressure, & a 12 volt ammeter, I unknowingly hooked it up the same way as th...

thanks Paul that video & manual were very helpful.

thank you all for the advice, that will help a lot.
