The front car feels like it isn’t running at all. No matter what I do with the flow meter the red ball doesn’t move on the front. She backfired a lot because it’s running way to rich IMG_2992.MOV It seems to me that the reason that carb isn't pulling any air is either linkage that isn't opening the butterfly or the piston is stuck at the bottom. Have you checked both of those? Link to comment https://www.classiczcars.com/topic/65207-carb-issue/?page=3#findComment-618610 Share on other sites More sharing options...

Alex240z Posted March 27, 2021 Author Share #27 Posted March 27, 2021 Found one of the issues. My timing was completely garbage. It was like 90 R. I put the engine in TDC and put the distributor back and put it at roughly 17 A. Runs a lot better doesn’t shoot gas out anymore. Drove her for a bit but tach died then my clutch screwed up so it doesn’t engage anymore which is fantastic. Carbs run alright but once I try to put it down to 700/800rpm they just die. I have to put the Jett nut all the way down to even drive. Link to comment https://www.classiczcars.com/topic/65207-carb-issue/?page=3#findComment-618648 Share on other sites More sharing options...
Alex240z Posted March 27, 2021 Author Share #28 Posted March 27, 2021 I got a carb rebuild kit so I’ll see what I can do. Might change the needle cause the one currently on the piston is pretty long. Not sure if that has anything to do with the amount of gas that it allows into the carb. I feel that I might’ve added too much oil to the dampers but idk if that has an effect to it. 1 Link to comment https://www.classiczcars.com/topic/65207-carb-issue/?page=3#findComment-618649 Share on other sites More sharing options...
siteunseen Posted March 27, 2021 Share #29 Posted March 27, 2021 Don't worry about the dampener oil being too full, it'll blow out. No big deal. My clutch wasn't working when I first bought my orange 240z. It wouldn't back up my driveway. There's adjustment on the pedal and the slave cylinder that I found. Fixed the problem until I replaced everything. https://www.google.com/search?q=adjusting+240z+clutch+classiczcars.com&client=ms-android-americamovil-us-revc&ei=ZJFeYL-LBdrWtQaNq4DIBQ&oq=adjusting+240z+clutch+classiczcars.com&gs_lcp=ChNtb2JpbGUtZ3dzLXdpei1zZXJwEAM6BwgeEAoQiwM6BAgeEApQjlhYx2Bg-nVoAHAAeAGAAa8BiAG8CpIBAzQuOJgBAKABAbgBAsABAQ&sclient=mobile-gws-wiz-serp Link to comment https://www.classiczcars.com/topic/65207-carb-issue/?page=3#findComment-618654 Share on other sites More sharing options...

Alex240z Posted April 13, 2021 Author Share #31 Posted April 13, 2021 So I’m back after long work on my car. I changed the needles and cleaned out the carbs. Finally worked! (Not really) car reeved at 2000 and increased over time at idle. Used starter fluid to check for leaks and guess that my intake wasn’t fully flat had to tighten it a little more. Also PCV was bad. Finally got the carbs to idle and got the correct fuel mixture! Onto the second issues the clutch. Haven’t figured out what the issue is with the clutch. The gears just will not engage at all when I push the clutch all the way down. It looks like it is engaging when I looked under the car. Not sure what the issue is. I have a new slave and master but no dice. Note that the fork looks weird. The pin was bad but I replaced it so it holds the fork properly.

Patcon Posted April 13, 2021 Share #34 Posted April 13, 2021 Are those pictures of the clutch fork with the clutch pedal NOT being pushed? If so the problem is inside the bellhousing Link to comment https://www.classiczcars.com/topic/65207-carb-issue/?page=3#findComment-619695 Share on other sites More sharing options...

I’ll take another photo today because I had to replace the clutch fork retaining spring because it went bad.

Patcon Posted April 13, 2021 Share #36 Posted April 13, 2021 So with the pedal down and the clutch fork pressed like that, it still doesn't want to shift? Link to comment https://www.classiczcars.com/topic/65207-carb-issue/?page=3#findComment-619711 Share on other sites More sharing options...
