Well I’ve been playing with the front carb on Friday I took the 5.5 power valve and exchanged it with a 6.5 and it had 70 and 71 jets in front so I put the 71 were the 70 was and a 72 were the 71 was and now at a steady speed on parkway it feels better less like it’s holding back. I actually think I need either air bleed change or PVCR a little bigger. After all this I adjusted mixture screws and it wasn’t to bad. But that’s not why I’m writing.
I’ve got the motor back with NGK iridium plugs and I wanted to put Autolite in there because I’m chasing an intermittent runs rough and I’ve been thinking it’s carburation. So today I figured I would start from scratch and go over everything before I changed the plugs so I was letting it warm up and it started to run a rough. So I figured screw it let me pull plugs and of course the last one #8 is wet. So I put the new plug in start it up and it’s still missing I check for spark and it has spark although it did seem to miss once or twice out of 10 times. So I pulled the brand new plug and it was wet. So I got my compression gauge and I pulled 6,7,an8 of course my compression gauge wasn’t working I think the Schroeder valve was bad so I went to the shop and got another and they were all between 170 and 175. So took an old plug put it in #8 and swapped #4 and #8 wires to see if the miss would follow it didn’t so I put the wires back the way they were. The wife called it was dinner time so I figured sausage and peppers would stop me from being aggravated.
So when I finished I went out and started it up and it seemed like it was running ok so I took it for a ride around the block and brought it back pulled #8 plug and it was clean. It still has the original problem carb wise but not missing so I cleaned up and called it a night till I get more time to play with it.
Now being the way it was with the plug being wet then not I was thinking maybe I have a pickup starting to go bad. I did have a extended cranking no start even at the reunion so I guess it’s possible. I had put one in already like 3 years ago with the old motor and it can’t have more than 300 miles or so on it. So I guess I’m gonna try one. Of course it’s a MSD I think it’s really a ford pickup so maybe I can get one from the part store?? I have an 8594 ditributor.
Or is someone thinking something else I’m all ears.
