That's what I though to, but I press the clutch pedal down and throw in first gear start the car and gas it, the car didn't go so I dont think the clutch is stuck engage.

Anyone knows if transmission fluid could be a issue with shifting? At the time they don't have 75-90 so I use some 80-90 none syn.?

I give that a try! I also adjust the rod on my slave cylinder, I had adjust it forward all the way and backward all the way but still wouldn't go into gear. Ok I remember when I install my new pressure plate it's seen to be a little thinner I believe, but not that difference. So I don't know if I got the right pressure plate or I just need to bleed it more and adjust the master rod? Im about to get a 280z tran with the fork and release bearing at the junkyard and replace it to see if that works! ( I don't know if I could use a 280z slave with none adjustable rod and replace it with the adjustable rod slave)? Any help thanks!!!

Help!!! I have a 280z block and tran. After installing a new 280z clutch and pressure plate, i could shift but it's hard, i have to force it in. I bleed the master and slave cylinder and i could see the clutch folk move but still hard to shift and reverse won't even go in it just gring. when turn off engine i could shift if i move the shift around. Note: car won't shift before i change the clutch and pressure plate. Any help big thanks

Thanks!

Its shifts when engine off! I try breaking the clutch loose but it won't work! I'm just going to look for a clutch kit and replace it, to see if it works. I have a 280z with a 5 speed trans. Help with clutch size!

Hey, need help here! My 240z with a L28 swap and a 5 speed transmission (vin# 7528541) won't go into gear after parked for couple days! I was thinking of a new clutch but don't know the size or the right clutch to buy? Any Help! (I check the slave and it have enough movement).

Sorry to jump in like this! I need Help! I've done researching but can not fix my problem! I have a 71 240z with a 280z 5 speed tran. I've parked the car for couple of days and decided to take it for a drive. I came home and park the car for a few hours and jump in the car again but this time I can't shift to any gear while the car's running. I turn off the car and it shift perfect. I have check for leaks, check Master cylinder, check slave cylinder and when I push the clutch pedal the slave move the clutch fork but still can't shift. Anyone have any suggestion to solve this problem? Thanks in advance!

I fixed, reconnect my 60 amp alt. and clean the flow bow and found that one of the seals on the flow was bad so change that and the car run fine! With no problem just need a tune to run better!

Thanks! I have been reading and have fix my issue! Car is running strong now!

Thanks! I forgot to check the idle speed! yup i believe it set around 1200-1300! I still couldn't figure out how to adjust the idle! Any help well be appreciate! But i'll do more read and hope i figure it out some day!

OK! i adjust my timing at 3000 rpm with 35 degree and at idle it's showing 20-22 degree is that right? I think i did it right? Anyone help?

Thanks for the info! but i would like to adjust my idle, it's setting at 1200-1300 rpm. Any one help!

OK! I have fix the issue! It was the alternator! The previous owner wire it wrong and it did't charge my battery so the car was only running on battery with nothing charging it. With that issue! My MSD ignition set didn't have enough juice to run properly. Thanks to all ya help! Now if anyone can tell me where's the idle screw for the Mikunis? so i can do my timing or can i just have someone rev it to 3000rpm?

Thanks! I'll try that converting!

Ok! I check my alternator and its a 12v 60a alternator! I believe it's a 280z or 280zx alternator? The previous owner Bridges the connector where it suppose to plug into the voltage regulator! He jump two wire for the light and one wire on the connector back down. I don't know if that's right? I don't see any wire coming back from the alternator to the battery! The only wire that's connect to the battery is the big red wire from battery positive terminal to the starter motor. Any one have the charging system diagram to convert external to internal voltage regulator for 1971 240z?

Ok! I adjust my timing back to stock and I use a voltmeter to test the battery after it was charge from the auto part store it show 12.5 volt and when I hook up the battery and start the car, it show 11.2 volt. I thing the volt regulator is bad? But can't located the volt regulator to test it. Previous owner had multiple wiring scatter around the car! (The battery came for my Honda so its smaller! My original battery is still charging.)

Thanks guys! Let me go work on the charging system and timing, and i'll update!

It's a 1971 240z, I'm new to the Datsun world, if you or anyone could tell me how to check the charging system? I could felt the fuel pump getting weak it could be the battery getting low but fuel pressure still show 3.8-4 psi. Next thing i'll want to do is drain out the fuel and refuel with 91 premium to see if that helps. oh.. and i just install new spark plugs but that didn't help.

Hey! I'm new here, just wondering if anyone can help? After pumping 89 unleaded fuel and adjust the timing, my car stumble and backfire when i accelerated. Before car was running on 91 premium fuel and it ran fine just a little lag sometime. Modded on car are: 44 mikuni, mild ported head, bigger cams shaft, header, 3 inch straight pipe, electric fuel pump and regulator set at 3.8 to 4 psi. One more thing some how the alternator wouldn't charge the battery so i crank the car multiple times and i could see fuel coming out on one of the mikuni. Any help well be appreciated. :disappoin
