I'm wondering where to start here.

I have a 1.7 with dual Webers that I need to get going (parents on my ass (IMG:style_emoticons/default/smile.gif) )

My initial thought is to just get it running "okay" enough to drive it down to a shop and have it fully tuned up.

Or I may just take the plunge and attempt it all myself (I'm thinking this is a bad idea)

What would the first step be?

The engine has hydraulic lifters. Does this mean I don't need to touch the valves?

The timing. Is this something a total 'newb' should attempt themself? I've been reading up on how to set the timing and it seems pretty simple. I've been thinking of getting a timing light.

As far as adjusting the carbs, I have no idea where to start.

As of now, the engine will turn over and sputter and seem like it wants to start, and occassionally will fire up for a split second but die off again.

Where do I start with the carbs? Any "how to" articles out there?

Where do I start in general?

I could really use some assistance here.
TIA - Zack

Junk in the carbs is a likely culprit. I have hydrualic cam/lifters/pushrods too. IF they are right you won't need to touch 'em. If they aren't right, unless WAY off, engine's ability to start and run (maybe poorly) should not be impacted. Look at the Pelican Parts website for timing guidance. With carbs, you can "static time" (no light used) and be damn close. If you haven't changed the plugs, they are probably fouled from trying to start it. Get an extra set of the Bosch coppers (nC-7 I think) in case you need to do it again.
To adjust the carbs, we need to know more. What kind of carburation is it? Dual Webers is common. Also dual D'elortos. There are some single carb setups as well.

I'm paying attention now-
Dual webers- prolly 40 IDA
Do the search thing. The jets are pretty accessable- idle jets are just below the fuel inlet behind 2 flathead brass screws, main jets from on top, in between the barrals, at the bottom of the emulsion tube which is screwed into the top with another brass flathead screw, just in from the venturi.
Hose those jets down with carb cleaner, and blast into the opening where the idles were pulled out
