Now that I've been able to get the timing belt on correctly and turn the engine by hand, I'm ready to tackle the next steps. Engine is currently sans radiator, hoses, v belt, intake manifold and carb. First thing I want to do is put on the intake manifold and carb. I've got the needed gaskets on order from Autoricambi, along with front seals.
I have the intake manifold in the basement, and a large assortment of carbs. Does anyone have any tips, tricks, suggestions for installing the intake manifold and gasket? Remember, this is something I've never tried before. Anyone know of a good write up I can refer to? Also, I don't know if I have the bolts. If I can't find them, any idea what size they are and where to get some?

Re: Installing intake manifold gasket
Nothing special about it. There are 6 holes in the manifold, there should be two studs in the head and the other 4 holes are for bolts. While the intake is off, now is a great time to remove and clean out the air/vapor separator if not already done. Also clean up or rebuild the starter since its such a pain to remove and replace. Maybe take it out, take it to a place that ONLY rebuilds starters and alternators and have them check it out (usually a free service).
Re: Installing intake manifold gasket
Intake is simple. Any manual will have a brief overview, but basicly just put it on and tighten bolts/nuts. Find one bolt that fits threads and head to hardware store for more if need be. Do not use sealant on gasket. Go for it.
Re: Installing intake manifold gasket
Thanks guys. That's one of the things I was going to ask, do I need any sealant or other stuff. Luckily, Autoricambi had some used bolts for the manifold, so I'm good to go there too.
Thanks for the suggestions about the separator and starter. I'll check them out.
Is there a specifc ft lb of torque the bolts should be tightened to?

Also a good opportunity to service the steering box.manoa matt wrote: While the intake is off, now is a great time to remove and clean out the air/vapor separator if not already done.
Re: Installing intake manifold gasket
Found that the hose from the air/vapor separator is cracked badly, need to replace it. So while I'm waiting for the hose, how do I clean the separator itself? The manual doesn't say. There is one bolt in the middle of it. Do I remove that bolt?
Also, I want to check to make sure the starter motor works. What's the best way to do that, since there is no intake manifold or carb on the engine? I'm guessing if I hooked up a battery now, when I crank the engine, the fuel pump would squirt fuel, but there's nothing on the engine to squirt it into. Or would the amount squirted for just a quick bump of the starter be nothing to worry about? I have already checked to make sure the engine has oil.

Re: Installing intake manifold gasket
no funny issues with the separator. just undo the bolt and take it apart. nothing odd on the inside to worry about.
The starter can be done in a couple of ways. I am assuming the starter is still in the car. I would pull the positive wire off the fuel pump so it cant run.
Other possibility it to make a short jumper wire. Disconnect your solenoid activation wire (should be the small red one). hook your jumper to the top lug on the solenoid and touch the other end to the contact where the red wire was removed. If you have the battery hooked to the starter, it will jump into action as soon as you make the connection.

Re: Installing intake manifold gasket
For safety reasons I would avoid making sparks with jumper wires near the fuel pump. Jump the starter, fuel sprays, release the wire, big spark...
Why not use the key to turn it over?? Plug and/or disconnect the fuel pump. Give it a whirl.
