My car is back together again, but a couple of wierd things..

Well a week and a half after I bought my 914, I had a dropped valve seat. Friends and I took the motor out, and got the heads redone.

The engine went together on Friday and Saturday of last weekend, and today we spent about 8 hours getting it back in and reattaching everything. The car started up great on the first turn of the key..however...

My gen light (alternator?) is on when the car is running.

We can only seem to adjust one cylinders worth of Weber correctly. At full close on the adjustment screw the cylinder still seems to run. Any higer on most of them and they start to backfire. Also we cannot use a unisyn because the venturi(?) tubes at the top of the air intakes are not there! (Remember I only had the car for a week and a half; I did not take anything apart yet.)

My plan is to take the car to a specialist to look and see if the alternator is actually making power, and to see what can be done with the carbs. If its running over 2000 rpm it runs great!

Any other ideas or experiences with these kind of issues would be welcome!

It's a '76 2.0, bored and cammed, dual webers

Brian

I would make some sort of adapter for the Unisyn so you can use it as it is just about mandatory for getting the carbs sync'd. say "adjustment screw" that is kind of vague as there are several for each carb and each barrel? Since you let the carbs set for a week, I imagine they might have sticking floats or goop from dried gas inside so I'd get them checked and adjusted. As for the alt light, I'd bet there is somethingnot hooked up of not hooked up correctly? Good luck.

Brian,

What are your engine and carb specs. You indicate "2.0L, bored and cammed". Bored to what and with what cam? Also what size webers, venturis, jets, etc.? With this info someone might be able to spot the problem.

I have more detailed info from the old work orders on the car. I'll have a look when I get home.

Check under the car. Is there a large fat red wire with a ring terminal on the end that is not hooked up to anything? That's the wire from the alternator to the starter. The battery connects to that same terminal on the starter, so that is how the alternator charges the battery.

If it isn't something obvious like that, then take a look through the "charging system troubleshooting" article in the 914 Tech Articles section of this very website.

Dave,

Thats exactly what is wrong. While putting the car together, we saw two big terminals and two cables. And the ground clip also...

Are you wearing that big metal strainer with the lights all over it that Doc Brown had Marty wear in Back to the Future?

I'm going to clean out my carbs tonight...

Thanks again Dave.

Nope, I just remember R&R'ing my engine, then wondering why the alternator light was on... And also how silly I felt when I noticed that big fat red wire hanging down.....

I'm just glad it didn't touch any sheet-metal...

Alternator issue is fixed.

A friend with lots of Weber and 914 experience is coming over Sat. morning and helping me get the other stuff ironed out. Hopefully I will learn as much from him as I have during the engine removal and replacement process.

Even though I am really impatient to get the car rolling again, it's been a great experience in it's own right.
