Also are new head bolts necessary?

Thanks for the advice so far. I asked the yard if i could get a refund if it is warped or cracked, they said yes. I defiantly plan on checking it to see if is warped as i could have saved myself some time and grief if i had done so when i first replaced the HG. So it sounds as though the answer to my question is yes, I can replace my head with a "new" head by keeping my engine in time during the swap so long as the replacement head has not been previously milled. The yard said the replacement head was complete with rockers and cam. Also my cam gear is already on the #3 position (i know i should replace the chain, this will happen during the winter, during a more complete tear-down), so if this is the case i will return the head and search for an un-milled one.

73 240z automatic e88 head The head on my 73 is most likely warped or cracked. I bought it this way. Tried to replace the head gasket and it still leaks coolant into a cylinder. I ordered a complete head from a parts yard, that i intend on replacing my damaged on with. My question is: can i replace the head in the same manner that i removed the previous one (wedging the chain at TDC) ? Or do i have to remove the front cover and start over with setting the timing?

Not particularly. On my car the hesitation seems to depend on how fast you open the throttle. I still have to adjust the idle and timing. As she has other problems not sure it it would be a good reference. I'll let you know what i find though.

Success! Idles and runs solid now. Rolled it out of the garage on its own power for the first time....then found out the brakes are gone. Fun times ahead. Thanks for the help guys!

Cleaning the idle jets got it to idle off choke. When i stabbed the gas, it would backfire out the carbs and try to stall. Just cleaned the carbs tonight. Hopefully that clears it up. Thanks for the help so far!

Thanks, that search phrase helped alot. Carb clean then timing, I'll get at it tonight. After a few hours of googleing i found this Weber DGV Rebuild - bluehandsinc.com helpful for reference!

So, I should clean fiddle with the carb before i set the timing?

I got the car with the carbs and this problem. It took starter spray to get it to run at all when i first got it. It starts faster and idles a little smother now on choke. Any suggestion on where to find a manual for these carbs. I have looked around but nothing so far.

Looking for some help with my Z: 1973 240 automatic, Weber DGV carbs Idles on the choke only. Will start with the choke off but dies within a few seconds. Replaced bad HG New valve cover, intake and exhaust gasket Drained fuel Changed fuel filter New spark plugs new oil, filter and coolant Changed what vacuum lines where left (most of the emission stuff was gone) Checked for vacuum leaks with carb cleaner, didn't find anything Compression looks OK Distributor is not locked down, wires to the thermostat are cut Any suggestions on where to go from here? Thanks!
