    You're so right, can't believe it wasn't carb related after all lol. I don't idle at 400rpm, but I also didn't want it stalling right below idle speed. I've got it set to idle when fully warm at...
  2. Ok, I kept going down in size of feelers until it...

    Ok, I kept going down in size of feelers until it would idle at 400rpm, so I'm guessing the size it requires is .004". I had to mill the bottom lip off each fin so it wouldn't scrub the pickup, but...
  3. Ok, set to .010", and it idles down to about 1300...

    Ok, set to .010", and it idles down to about 1300 then loses spark. Set to .008", and it's down to about 1000rpm, any lower and it loses spark. I tried adjusting to .006", but the very bottom...
  4. Ok, I reversed the polarity on the ignition...

    Ok, I reversed the polarity on the ignition control module, where it reads the spark trigger, and it fires right up and idles fine(with a slight hiccup every so often). So used that time to make...
  5. Well, I found something interesting. When I...

    Well, I found something interesting. When I began to idle it down, the moment it starts acting up is when the spark becomes erratic, then I lose spark and it stalls, then regains spark the second it...
  6. Sticky: The first ones are the same as what I had on my...

    The first ones are the same as what I had on my 70 240z, can't find them now and have no idea what brand they are, can anyone help? The second ones are Keystone Turbines(no clue if they're legit or...
  7. Well I stopped trying to figure it out for now,...

    Well I stopped trying to figure it out for now, got alot of body work to do. But if someone could confirm their advance at these 3 rpms, it would give me an idea of which way to adjust. With the...

    Yes, I can take more pics. All vacuum hoses that lead directly to a vacuum source have been blocked off, so any/all accessories you see with vacuum hoses are just dead hoses. I'll eventually mill...

    I borrowed a pair from my buddy off his 240z, and they did similar, but what they would do is let you idle it down to 700 and stay running fine for a while. Then after about 5min or so, it would...
  10. No, not on the base timing setting, it said in...

    No, not on the base timing setting, it said in the instructions that it wasn't necessary, because the adjustments were fully mechanical. I did use a timing light to check max advance at 3500rpm, and...
  11. I set it per the instructions for the dizzy. Set...

    I set it per the instructions for the dizzy. Set the dizzy so the rotor is centered on the #1 plug wire contact, align the dizzy to the 0 mark on baseplate, stab dizzy so baseplate mounts to engine...
  12. I thought the same thing about the timing,...

    I thought the same thing about the timing, especially the way it reverse rotates, but it not hard to crank(actually very easy to crank).....my camaro is base timed at 18degrees advanced, so I know...
  13. The smog stuff is actually unhooked at the...

    The smog stuff is actually unhooked at the source, only using blocked tubes to seal off any leaks, I haven't gotten around to making the blockoff plates for everything yet, as this current issue is...
  14. The needles are in the same place, but when fully...

    The needles are in the same place, but when fully warmed up, it does get a teensy bit of sooty exhaust when you get on it good with no load on engine, so I might play with the height of the needles a...

    Here's how she does when easing off gas, started shaking a little at 1800rpm and fell on it's face at 1700rpm.

    Well we're still using a kit we got a couple years ago that included new valves, we've run the engine with the drain screws removed and the "hollow screw to clear vertical tube" method to make sure...

    Yeah I was mainly just wondering for labor cost.....my guys' time is worth alot more than my spare time, so if something is to be done and will sell alot for a good enough price, I'll put one of them...

    Yeah I'm running an AD244 alt with a v-belt pulley swap to an external regulator with high amp internals, ampere gauge swapped to high-amp ampere gauge and volt meter combo gauge, and everything...

    Exactly, nothing is making sense here.....I've been having this exact same problem since I joined the site, surprised my patience lasted this long to be honest. All gaskets on the engine(minus head...

    Yes, we have completely disassembled and cleaned every part every time we take them down to check and readjust float levels. These are the round-top SU carbs also, forgot to mention in the original...

    We always check the fuel level with a clear hose attached to a hollow screw that is screwed into the bowl drain spot. Then stand the hose up beside the bowl and turn the fuel pump on.

    As far as...
  22. Weird dysfunctional SU carb issue, rebuilt and floats reset going on 8 times now.....

    When setting to idle speed, I can't get the rpms to go below 1550, else the engine will just die and chug smoke out the carbs when it dies(seems to reverse rotate a little when it does that). We've...

    agreed....get a euro balance tube with block plates installed so the air doesn't share, then run cable lifted carbs, instead of the SU carbs. Got ahold to (2) 42mm mikuni's i'm working on fitting to...
