Team, Im hoping someone is willing to pinch a pair of these from their calibration pack and send my way. Edelbrock #1955 rods .067 x .037 will be marked 6737 on rod. Jets #1429 are .101 and will be marked 401. Thanks for looking.

Forgot to mention, includes original jets and rods as well.

Reduced price to $180 after reviewing other carbs sales

Great shape 1403, good choice for warmed 318 or mild 360. Ran for years on my 360 and finally upgraded to a 1906. Currently jets/rods for 2 stages rich. Comes with new gaskets, choke wires, etc that come with new edelbrock. $200 shipped. Thanks for looking.

Carburetor sold, other items still available.

It has been together around 2 years, and i romp on it continually. I have around 15” vacuum at idle. I put the pink springs in and they helped. Which seems weird, there was no off-idle stumble issue. Smooth transition to partial or WOT. So far, rattling is gone. I think the carb is very lean...

Yeah I have been eyeballing the 650 avs2 for a long time, comes quite a bit richer out of the box. If my needle change (2 stages richer in power mode) is a step in the right direction I might just go ahead and pull the trigger on the new carb and start tuning that. Reading the Edelbrock...

Ray, new spring helped, slowed the timing curve but did not completely get rid of the rattle. Phreakish's comment "An engine can "run great" while slowly, or quickly, destroying itself. Simply jumping at the timing may not be the solution to the issue. Ignoring other possibilities is a great way...

Thanks for the tips. After confirming TDC, I went back in to take a look at the carb. Did a full throttle pull, killed engine and pulled plug, it showed almost completely clean. Ordered needles (Edelbrock avs) to go richer. Will see how that effects things.

Price on carb reduced, $180 shipped.

Kit is worth every penny.. even if you have excellent soldering/electrical skills and enjoy making your own harness, its a good value just for the price/quality of components he is buying in bulk. If you are like most of us and don't particularly enjoy wiring, the kit is a slam dunk. Bright...

Again, you are free to move along. Others have been very helpful, you have been rude. You can't ignore all previous information shared in the thread, give a shotgun blast of condescending generic troubleshooting instructions, and then get angry when I don't immediately ignore everyone else and...

To address the latest posts in order, sorry I generally only get on here once a day. Working long hours.

Thank you, I understand and acknowledge that the dampener may have spun. I was addressing ray's timing light concern. I'm not 'disregarding' anybody. I am also not in the habit of taking orders from impatient strangers on the internet. We are engaging in some troubleshooting discussion on a...

Cast-in timing marks on cover agree with the light when dialed back, 10 BTDC. Timing light with no-dial back, lines up with 10btdc mark on cover.

Only other thing i could think of is fuel quality… maybe varying octane in the garbage 87e10 i feed it?

Before it ran at 14 base timing with no detonation (last fall). I just bumped it up to 10 and got a minor occasional rattle around 2500-2800 under heavy load. So looks like 8 or 9 is what it wants. Feels very strong at that setting and idles well, so maybe dampener slipped by 4-5 degrees?

Nope, rubber looks fine. It is the original dampener though, maybe it has only slipped a bit.

No, don't have time right now to fabricate a piston stop. I'm operating on the assumption that it has. Do they generally slip towards retarding the marks? I.E. making it look like the timing is much more retarded than it actually is?

Mail came, installed the new spring this afternoon. Bigger/more coils but felt about the same by my non-calibrated stretching. Put everything together, set base timing at 14 and confirmed total was 36 by about 3000 rpm. New curve seemed just a bit slower, still adding in about 6 degrees at the...

Edelbrock 1405 600 cfm carb, manual choke used good condition $200 shipped. FBO distributor limiter plate new unused $30 shipped. oem adjustable Chrysler vac can curved arm marked 7R (14 crank) pn 4091663. $25 shipped. oem adjustable Chrysler vac can curved arm marked 11.0R (22 crank) pn...

Have everything in the distributor clean and lubed, ready to go back together just waiting for the mail.

Exactly i was not touching the carb at all and trying to restore idle to normal with timing. Had me chasing my tail.

Yes, post #27, took distributor apart to check but of course hard to verify a weak spring by looking at it.. and I didn't want to start revving motor until I put everything back together and manually turned over the engine with breaker bar while watching rotor to ensure no slop or play in cam...

You nailed it, thats exactly what was happening, but at lower rpms (between 650-1050) where no mechanical advance should have been coming in yet.

Ok folks, thanks for all the brainpower, just got off the phone with Ray and we have the issue figured out. Weak small spring in the advance mechanism. What was happening was the spring weakened with time, 7 months of storage, and that it was adding timing at idle and under 1k. around 750 it...

Pertronix collar is tight and wires are in correct order, have been using same unit for years. But the issue does seem to correspond to heat… maybe it is electrical somehow. As far as distributor advance springs, they looked fine. One heavy, one light, working as advertised. I guess i can pull...

Well that turned out to be a rabbit trail. Rebuilt distributor, reinstalled in car... and EXACTLY REPLICATED the issue. Warmed up, set base timing to 12, went for a spirited drive, started rattling at 2k-2500... checked timing again.. up to 22. At this point, evidence seems to be pointing to...

I think I found the issue. One of the pins that the advance weight pivots on is very loose. Currently cannibalizing the distributor and assembling another from spare parts. We will see what happens.

Just tore into the distributor, point plate seems securely fixed by vac-can. When vac is applied, it moves smoothly, snaps back when released. There is some minor corrosion on the weights, but everything seems to be good.. roll pin is intact and not sheared, I just don't understand what is going...
