Help! Guidance and affirmation needed

True to form, I’ve fully paralyzed myself by over analyzing this situation…I honestly think I’ve read every post and FAQ on this forum 2 or 3 times in the last few days. Last week I acquired “Miss Bianca” as my family and I have come to call her. Bianca is a ’76 2002 that not surprisingly comes equipped with 37 years worth of issues that need to be addressed. Really wanted to have my local guy do the compression test during the PPI but the PO brought the car in warm and given the scarcity of 2002s around here I didn’t want this one to slip by as everything else checked out so I opted to pass on the comp test up front.

The most pressing issues right now (aside from some surface rust) are cold/warm start and extreme sluggishness in the 1000-2800 rpm range while running. On a few occasions the car has fired up after a couple cranks but I’ve found it generally is takes around 6 or 7 attempts and sometimes many more to get the car going regardless of engine or outside temps. This is my first carbed vehicle so dialing the appropriate mixture is new but I can’t see any immediate signs that suggest anything is off there.

The only aftermarket “upgrade” that I’m aware of at this point is a rebuild kit 32/36 DGAV that the previous owner added within the last month. I’m assuming this carb and install are the source of the majority of the problems. In addition, it looks like some of the SMOG crap (as someone on here so eloquently put it) has been removed. I have some concern that some ports that need to be capped or plugged haven’t been (will share pics of carb and manifold when I get home from the office).

My focus this weekend is to ensure all of the carb linkages (throttle, choke, etc.) are well lubricated and in good working order and then begin to run through a checklist of potential issues (i.e. vacuum leaks, fully functional choke, accelerator pump, jets, etc.). I also have on order the Tii mechanical advance distributor repro from IE, new 8mm wires, and NGK plugs to help take care of any issues on the ignition side of things.

My buddy and I are far from experts in 02s and are really looking for confirmation on the initial approach.

If our efforts Saturday are no help I’m thinking compression test and valve adjustment are the next steps? Thoughts? BTW I’m happy to provide the bourbon, beer, and pizza for any locals that may want to drop by and lend a hand or just point and laugh.

TL DR (version): I'm a noob that needs help and guidance on some fairly common issues. Have Haynes manuals and BMW shop manuals and have read every post related to the above topics on this site.

Id probably, make sure your choke is working , everyone has their own starting method mines pull out choke (manual choke not water or electric)couple of pumps on the gas pedal ... away she goes.

My carby is adjusted correctly as is the timing. So if the PO rebuilt the carby , has it been adjusted? Is the timing correct? Check vac leaks, I think your heading in the right direction though.Id address this first before worrying about a comp test.

I'd start on the electrical side first. CHeck/clean plugs, timing, point gap/dwell, dist. cap, rotor, make sure wire connections are solid. Then you can go to carb. Vacuum leaks is top priority. The basic question (for which you may not have the answer) is: did it run well before? If so, check fuel bowl for grunge. Maybe old gas issue. Maybe pull jets to clean and verify with proper settings. Check accel pump by looking down carb throat and moving linkage - you should see good squirt of fuel.

Where are you located?

Whoops...forgot that piece of info. I'm in Louisville, KY

Definitely appreciate the suggestions provided. Also if it helps my initial findings on the choke show that the plates are opening fully when the engine is warm. Also it appears the fast idle link/rod is sticking which causes the car to idle higher than it should...2000 rpms when warm.

First, if the PO just rebuilt the carb, I would suspect he was having some sort of trouble. My belief is that owners only rebuild carbs when it is too late, when a car is running miserably. Second, do you believe the PO was qualified to rebuild the carb? Could he have missed an issue (with the carb) entirely? If this weekend's examination and review yield nothing, I'd be tempted to rebuild the carb, or to have a Weber guy/gal rebuild the carb and set it up properly.

Good luck,

Steve

Carb (engine warm)

Note cracked fuel supply (this is going to be fixed immediately)

Could probably use a good cleaning and some lubrication

Choke angled correctly?

Do those other openings on the manifold need to be plugged as well? If anyone notices any other glaring issues please let me know. Thanks again guys.

Steve,

I have no real reason to question his ability but he certainly moved away from the 02 rather quickly following the rebuild so there is definitely some concern there. Car was advertised fairly so at the end of the day I have no problem with the way things are just need to get these issues addressed.
