    I'm currently finishing up the restoration of my '72 240z and looking for my next Z project.

  1. I have a set of triple 40's on my 240z that I'm trying to dial in. I had a low RPM stumble that I cured by moving up in jet size from a 50F9 to a 55F9. In the process of doing swapping idle jets, my idle mix screw is now only about 3/8 of a turn out and I'm having some rough idle issues and richness. I'd like to try an idle jet that is right in between the 50F9 and the 55F9 but I'm not sure which one that would be - maybe a 55F8 or 55F2? I've seen the chart showing the F# order from lean to rich (attached), but I don't know how a 50 series F chart compares to a 55 series F chart. Is there
  2. Hey Blue - I can't find that pipette tool you mentioned above. Do you have a link you can post that would point me in the right direction? Thanks! Steve
  3. Hey Blue - I have been working on setting the float levels of my carbs today and just ran across this thread. Great idea!!! One question though, I assume I should use a carb gasket between the carb top and the bowl to simulate the correct height of the floats relative to the carb body? Also, does anyone know how to get a hold of Keith's float level tool? I didn't see it on the website with his other stuff. Thanks! Steve
  4. Chickenman - Thanks for your feedback. Isky sent out new .175" lash pads with the cam. Rocker arms are the original arms that had about 64k miles on them. They looked very clean and showed no noticeable signs of wear. I still haven't heard back from Isky. I called yesterday and was told that Ron was still working on the numbers. If that's the case, then I assume there must be a mistake on the most recent cam card he sent me. If I get some new numbers from Isky, madkaw and I will probably take one more run at dialing in the cam and I'll post the new cam card. If I don't hear somethi
  5. Hey all - thanks for the replies. I'll see if I can get some of your questions answered. I have received two very different L-480 cam cards from Isky - both for a Datsun 6 cylinder L series engine. I have attached both for reference. The card with the writing on it is the most recent one they sent me. I have been working with madkaw on this since he has far more experience dialing in cams than I do, but he is stumped as well. Zed Head is correct in that I don't know if the cam card is wrong or if the cam is wrong. This was supposed to be a regrind of my original cam, but I can't te
  6. All - I just recently had my stock cam reground by Isky to an L480 grind for my '72 240. I received a cam card with the cam but the information on the card was not correct I talked to Ron at Isky and he sent me a different cam card and it appears to be wrong too. Using a degree wheel and a piston stop, I have dialed in my engine for TDC but none of the open and close numbers on the cam card are very close to what we have actually measured. All measurements were taken at .050" valve lift with zero lash. I talked to Ron once again this past Friday and he said he would run some numbers a
  7. I started looking for a lift after I completed my 30x32 attached garage/shop two years ago. I had the same concerns about the lift being in the way depending on what I was doing. I considered 2 post lifts first, but decided I didn't like the posts being in the middle of the garage AND the lift was not moveable. I thought about the scissor lifts, but like you, realized that the middle of the car would not be accessible. Finally, I looked at 4 post lifts and that is what I settled on. They are more expensive, but depending on how much ceiling room you have, it can actually create more space
