Rusty's not very quiet cuda progress

He's a glutton for punishment, got all the pieces fitted up for the final cuts & then started cutting out the lower corner of the cab!

He's gonna por 15 the rest of the frame.
I gave up on that stuff after the problems it caused on the first car, I guess for under there it's fine?

I'm not convinced that stuff is any better than Industrial Rustoleum. I've got black paint all over the floor from laying under the Duster brushing that stuff on.
 
First car I had a few issues with it, other parts held fine, & I tried to follow their instructions to the T.
This car is all spray bomb rustolium rusty metal primer everywhere, lot of people po poooed that, so far nothings peeling off?
 
Kinda back to square one, Go out today & start her up, geeze the gauge is reading just over 4, hasn't done that in awhile, so I play with the adjustment which is almost all the way in, this reg. is supposed to be from 4 to 10LBS.
Would not go up much, so I set it at 3, let her run awhile it then dropped to 1 & even lower, barley over zero, the idle speed or sound of the engine never changed.
So I'm like I can't trust this thing, remembered I had an in line gauge somewhere, dug around a bit & found it, removed the reg. & put that in started her up & running around 7.
Still no response from the carb adjustment screws, it did stall when I covered the top of the carb, checking the vac leak deal.
Pulled a plug before I took the test drive. 20250328_125839 - Copy.jpg20250328_125852.jpg20250328_122538.jpgtook the test drive, actually seemed to idle a little smoother, no big clouds of smoke, went on some main roads so I could at least do 45-50.
Kickdown worked again & got another nice chirp
Cooled it down a bit & piled the plug again, doesn't look terrible to me, I'd say the exhaust stinks a bit more, but no big black clouds, some gray puffs.
Same plug (#1) 20250328_161609.jpg20250328_161617.jpgAt least it was nice to be out of the garage! 20250328_133130.jpg
Gonna try & get a video up.

The new setup............20250328_125241.jpg
 
With an Eddy carb your idle fuel pressure should be no more than 6 psi at idle. The 2nd pic of the plug is a major improvemnt over the 1st. But still slightly darker than ideal. It seems that you are getting closer.
 
Well now we went through 2 pressure regulators, I hesitate to buy another, but it's now an easy setup.
I keep going back to your fuel filter with the bypass, but that will be a pain trying to turn my vapor return line into a fuel return, I do have a return stub on my fuel pick up unit????
So it's not connected to anything up front & out back just pull it off the Seperator in front of the tank & hose it over to the return stub, just don't feel like crawling around under there.

Will 1 lb less actually make the adjustments work, the mixture screws do NOTHING?
 
OK I'm dense, so if they are the only source at idle, where is the fuel bypassing?
Even when It was supposedly running at 3 lbs, the screws did not have much effect then either.
Still trying to decide if I see if summit will warrantee the reg. if so it's easy to try another all set for it.
Or mess with converting my vapor return to a fuel return & try 68's bypass fuel filter?
 
Alright, today it was 1 pump & it fired right up, but I don't think it caught high idle, it started dying & I had to give it a little gas till it warmed up. (cooler in the garage maybe 55/60?
Guage was showing 6 lbs, so I messed with the screws again, just as I got to closed I noticed a slight decrease in idle?
Went back to open both 1 1/2.
So I let it cool down it's still about 75 out, I pressed the throttle & checked, it did not catch high idle, so I set that by hand & fired it up, on high it didn't try to die & stayed running, after warm there was not much exhaust smoke but it smelled pretty strong, Mark said try the screws now, went in 1/2 turn each, that actually did something, not really nasty standing in the exhaust.
Left it there till the next test drive.
Sooooo, first will the high idle set in warm weather if so I have to figure why that's not working, gonna try & find the book & see if they mention that?
Oh yea, the pressure was back to 7 thru all that.

With the "vapor separator" (filter) all that's needed is to plumb the return line anywhere prior to the fuel pump. Because you car did not originally come with an Eddy/carter style 4bbl you need to regulate fuel pressure for it.

When I swapped the 2bbl on my 318 for 2x4's, (Carters), I added the vapor separator filter and plumbed it with a "T" fitting just prior to the fuel pump.

The factory used a similar system on cars that came with Carter 4BBL's, but they plumbed it all the way to the tank.
 
I have the return line in there that was meant for the vapor return, at the tank fairly easy (cept for crawling under there) just cap that little tank in front of the gas tank & run the line to the return that's now capped at the pick up.
Up front it's way up the front of the inner fender, either hose it up there or cut it down by the frame rail & tie in, it's doable, I'm just not enthusiastic about doing it!
 
OK, so today I checked that it set the high idle & it did, still started to die on me, gave it a little gas to keep it running till warm, kicked it down & it did stay running, put it in gear & also stayed running, so before I came in I raised the high idle one turn, will try again when cold tomorrow!
Now on the high idle lever, these 2 spots I can set it at, the top point (the tip} & then the notch below that, I manually put it on that top one & the idle was very high, are there 2 points or is the first notch the spot, brought in the book to see if they mention it?
 
Read some of the book on the carb, seems the point it set at is correct point on the high idle.
There's like 1000 settings on that carb way over my head at the moment, but I noticed one curious thing, they say fuel pressure over 6 1/2 is too much, could 1/2Lb cause all this chaos!
Trying the startup in a little while?
 
Whether or not 1/2 lb will cause chaos is kinda moot. Can you attest to 100% accuracy of the gauge? In my opinion anything between 4-5 lbs would be adequate for any driving style. I'm running a vapor separator/filter on 3 of my cars, all with Carter carbs. 2 with electric fuel pumps and one with mechanical. None have issues of richness, flooding, starvation or erratic idle.
 
Crap I forgot to hit post, this would have been up , not that it would effect your answer, but a tad more info?

I'm feeling that it is sooooo close as long as it runs on the road good & it's not so rich to hurt the engine I'll call it close enough & close the darn book!

So below was todays quick test, I'm still trying to convince myself I won't get stuck & take it a few miles out to hit an actual highway & stretch her legs a bit!

Today I gave it 1 pump & went out & checked, choke closed & on the high idle lever, she fired right up & stayed running, went out & watched as the choke opened, idle sped up some as it opened.
So it went to almost full open, if I push with my finger it moves maybe an 1/8" more.20250331_143835.jpgThe setting on the choke is a couple of notches towards lean, didn't mess with that yet. 20250331_143851.jpg

Don't be too concerned with the markings for the choke. They are mostly as a suggestion. Try to keep it somewhat on the lean side, but not to where it may cause a stumble or pop back thru the carb. You want it to respond quickly with zero hesitation
 
So far it has responded well to a short burst from a roll, have yet to get up the guts to venture a few miles further to hit a highway where I can stretch her out a bit.
Weathers getting nice, a few more local rides may convince me she won't poop out on me?
 
Today she again fired right up, stayed running a while & then did that die out thing, so I restarted & sat in it with a little gas till she was warm, kicked it down & it stayed running.
Took it around the hood & then hit the main streets, 35 on one & 45 on the other, drove around for a half hour or so, tried the kick down twice from a roll, 1st time I eased out a bit & it shifted to drive around 50 or so, second time I stayed floored & considering where I was I had to back out around 70mph it didn't hit drive yet.
Felt more comfortable at lights the idle didn't feel like it would stall, so a couple things I noticed.
1st the oil warning light kinda flashes on & off when idling, goes out as soon as I start moving, not hearing any rat tat tat's
2nd thing I'm not sure about, as I was slowing down for a light it dropped into second, did it a couple of times, is that right when your in drive?
Don't remember my other "Cuda's doing that?
So after it cooled down a bit I pulled a plug (same #1) Me thinks it looks a ton better? What say you guys!20250402_162755.jpg20250402_162808.jpg
 
That spark plug looks perfect but if it idled at all before you pulled it it is only giving you a read of the mixture at idle. To see what it is doing at part throttle or at cruse you will need to hold the throttle at a steady speed, shut of the ignition, click it into neutral and cost to a stop then pull the plugs, then do the same at wide open throttle.
