I pondered that last year. Got involved with getting a LSD. Just finished converting a R180 out of STI and it fits so much better than the R200 I had built. Need to stop screwing around with it a spend time in the seat. Keep in touch. Don Sent from my iPhone using Classic Zcar Club mobile

Not yet. Haven’t come up with plan I like yet. I will spend some time on that soon as I have plans to replace the head with an E31. I’ll be curious what you come up with. PS. Hasn’t caused a problem yet though. Sent from my iPhone using Classic Zcar Club mobile

Great information. I am hoping to find time soon. These motors are so strong that I have never had to pull on off either of the two I’ve own over the last 22 years. Thanks for the help. Sent from my iPhone using Classic Zcar Club mobile

Great information everyone. I think i will go with the ARP Studs, and find some Copper Coat. Found a chain tension wedge online for $10. Head was worked on by madkaw .

#240260280 Thanks for your quick response. Any suggestions on a good source for the head gasket?

Beginning the installation of a different head (E31) on my 72 stock engine. Are new head bolts a good idea? Non turbo or Turbo? Where would you buy them? Are new studs better than new bolts? Where to acquire the timing chain wedge? Other recommendations are a[appreciated Don.

Mark You are trouper for hanging in on those problem. Here are a couple things that come to mind: When cold starting my 240 w/Ztherapy carbs I immediately reduce the amount of choke once it starts. As the engine begins to warm the rpm’s will increase. Then I start Reducing the amount of choke. It is my understanding that when the choke is used it automatically causes the butterflies to open slightly allowing more air to enter. With all the misc adjustments I wonder if they open to much causing a lean environment? Last thought: at almost four full turns isn’t the nozzle lower also and does that require more vacuum/suction at start. Has he checked for vacuum leaks? Sorry as I hate to muddy the waters.

Here is my experience with a stock 240 with 12 yr old Ztherapy carbs. On cold start up (after a sitting for a couple days) I pull my choke all of the way on while starting. Once it fires I reduce the amount of choke enough to let it idle at about 1200 rpm or so. As the car beginnings to warm the rpm’s tend to increase allowing me to reduce the amount of choke. Eventually I am able to completely shut off the choke and it idle in the 800-1000 range showing on the tach. Ps; running on a mechanical fuel pump. Good luck Sent from my iPhone using Classic Zcar Club mobile

Idle doesn't decrease-sometimes surges-when shifting

Could be your nozzles are sticking and if your are running rich I’m not sure you show be at four turns. See if you can replicate the high idle while sitting still Then push upon the nozzles up to see if they move up. Sent from my iPhone using Classic Zcar Club mobile -

I had this problem when I installed an after market balancer. The belt would work for a while and the get hot and then slip. Tried a bunch of different belts and could never cure the problem. Found a single groove nissan balancer and installed it. Good luck.

I have none of Olly since 1995. This will be his fifth shop since then. Fairly savvy Datsun guy. He always has a bunch of old car and a shop full of parts, none worth his price which is why he so many. Plus he is just plain WIERD. If any of you want something let me know and I will go by to check it out. PM me Don Sent from my iPhone using Classic Zcar Club mobile

Be sure that the choke cables are disconnected. It can distort the locate of the nozzle. Sent from my iPhone using Classic Zcar Club mobile

There maybe enough crud in the tank to block the out line inside of the tank after some time. Sent from my iPhone using Classic Zcar Club mobile

Mike I have this cover and like it. It is soft and easy to out on or off. Folds up small. I have never left it on outside of the garage so cant speak to how it handles the weather. Don.
