Guess I need to relook at that. I'm running 20 degrees initial. Seems to like it there. I've tried 5 and 10 but 20 seems to be best even with a vacuum gauge.

I've been playing with my newly rebuilt 273 with a 600 CFM Eddy on top of a 3/8" insulator. After too much tuning I think my hard start when hot problem is because of fuel boil off. If I try an immediate restart there is no problem. Cold start is also excellent but after sitting about an hour it...

Just a quick update. Auto Zone gave me back $100 for my time, trouble and expenses. I installed a new ProForm dizzy and am in the process of tuning it because the advance comes in way early off idle. I'm almost there with it and the car drives nicely. Good idle and no hesitation or bog when...

I haven't had the opportunity to do much driving with the problem I've had. It's definitely NOT the carb, fuel pressure, etc. It WAS the distributor from Cardone. I did get to speak to a tech rep today and he was just pretty much speechless when He told me they don't usually have a problem...

Actually, my fuel pressure is fine with the mechanical pump. I got the higher reading because I'd disconnected the fuel line and plugged it directly into the gauge. I fully intend to go back to base on the carb and retune. I've had this ine apart so many times, I should be able to do this in my...

Thanks Old school. One of my friends came over today and brought his pertronics ignition set up. We installed it and "Voila" -- the car pulls and pulls and runs like a raped ape. I tookj the dizzy back to auto Zone and asked them toorder me a new one. Cardone is out of stock. I told the...

Well, this morning I got back at it. Figured I'd warm up the engine and hook up all the test gear. I noticed that when I put the timing light on I got to 36 deg advance but when I kept opening the throttle, the tape swung way to the drivers side and I was looking at over 60 degrees advance. What...

Hey old school, I have a cardone reman that I had checked on a distributor machine. The guy seemed to think everything was good with it. I have vacuum hooked to timed port and have also tried leaving it disconnected. I've tried the timing all over the place, have set it with a vacuum gauge at...

Good to hear someone else is building a 273. I'm interested to know how yours runs when you drive it. Mine idles beautifully. Just can't seem to get it to transition out of cruise mode. Changed my primaries to 101 with no noticeable difference. Friday I'm going to change the secondaries to 98's.

Thanks Prine. A lot of people have commented on the fuel pressure but it bogs with the fuel line disconnected so I've discounted that theory. I'm running a 2" exhaust except for about 3 inches of exhaust pipe on both sides which is stock 11/2". Seems the muffler shop took the easy way out when...

Got my kit today and changed to the 70x37 rod with not a lot of change. Then U tried jockeying the timing. Retarding the timing to about 5 after seemed to help some but the car is lazy. I started twisting the dist. to advance and Im probably 20 BTC and it runs better but doesn't sound right...

Yes to both Rumblefish. I ordered a whole kit today and am going to really fatten the rods up and see what happens.

Well, I changed the squirter to the 024,and the metering rods to 073x42 with plain springs. It seems to help a little but I'm still getting the bog. Any one else have a suggestion?

I already have a 3/8" insulator which seems to really help with hot start. Timing is 10 BTC set with a vacuum gauge. Seems to like it there for starting.

ordered the kit -- I'm like a kid a x-mas.

Thanks for the comments guys. I hope I can get this sorted out also. I've put a lot of work into this little car and have more to do but want to get the mechanicals finished before moving on to other oarts of the project. I'm going to try "oldschoolcuda" suggestion about the smaller accel. pump...

Started with the pump in the middle, moved it up, tried all the springs in the kit. Now I'm looking to move the pump down to the lowest hole and go through the springs again. I don't see any black smoke on acceleration so I don't think I'm too rich. That's what's got me confused and I don't...

I'll work on that Tues and post my results. I was thinking of trying the weakest springs and last hole down on accel. pump. Work springs up from there. If that doesn't do it, I need to look at the metering rods. That's why I'm looking for someone else that's experienced the same issue. Harv

I have a new 600 cfm 1406 Edelbrock on my newly rebuilt 273. It has a D4B hi-rise, stock .030 over flat pistons, an electronic ignition and mild cam ( duration 240/240, .050 duration 212/212, lift .290, valve lift .435/.435, centerline .106/.114, lobe separation 110). My idle vacuum is 18" at...

Do you have the heat shield on the driver's side or did you use an angled boot? Where did you get them from?

I'm finishing up a 273 build but had no plug wires rom the beginning. Now I need to buy a set of wires and have to mix and match the angles on the boots as I don't have a left side heat shield. Is there someone out there that can give me measurements per cylinder # so I can go to my local supply...

If your old BBD doesn't have the electrical emissiions junk on it, I'd be interested in it if the shafts are still pretty tight and it's rebuildable. I need one for a 273 I'm building. Shoot me a price shipped to 38049 if you're interested in selling.
