Hi there, good numbers on the compression test. Doing the compression test is about the same skill level as setting up the Spica, I would consider doing it yourself. Does it have a thermostatic actuator (TA)? Likely. You will need to know the T number off the spica pump to know if your pump wants a 27 or 29mm extension. Make yourself a dummy actuator, set the bell crank stops by borrowing the tool or use a digital protractor. Then pretty much most of it can be set on a non warmed up engine. It is a step by step process from beginning to end. Lots of help and support here.

Cheers,

Thanks. I thought about doing it myself. I even bought a crank stops tool. I decided not to for a couple of reasons.

First, my former mechanic, who has decades of Alfa experience, could not get the engine to run correctly with the pump that Wes rebuilt. He kept telling me that the pump was bad. I sent it back to Wes and he would test the pump a say that it was fine. Same result when we got the pump back. My former mechanic put his pump in my car and my car ran great. The rebuilt pump same problem. So back it went across the country. Wes tested the pump again and told us it was fine and sent it back. The T/A tested fine at 29 mm. My former mechanic put the pump back in and cranked it very rich to get it to at least run. It also idles at about 1500 rpm's. He told me to drive it the way it is and enjoy it. I don't think that my former mechanic followed the instructions that Wes provides tune the new pump.

Second, although I have owned this car for years, I don't know enough about this engine. I knew that the compression was quite high but didn't know why. It appears that the engine has Borgo 10.4:1 pistons. I still don't know what else has been done to this engine other than both standard cams have been advanced. We are assuming that the head has been shaved put don't know if the valves are oversized. Would anything done to this engine require a higher performing Spica pump?

Hopefully this new mechanic will be able to get this engine running properly and make this car a pleasure to drive.

Two things, if your mechanics personal SPICA pump ran your car perfectly, find out if his is a regular SPICA or a "performance". If it was a standard SPICA chances are thats what your car needs (in the end, whether it be this one or another).
Second, running a car rich for a while is a good way to eventually wipe out the piston rings from the gas washing off the oil, though I did catch that you are no longer driving the car.

Dumb question, when your mechanic switched the two SPICA pumps, did he switch the pump single or did he switch the manifold and other parts?
I find it odd that your car ran with his SPICA, but not with yours, and Wes has inspected your pump more than once.

I understand your frustration, faulty fuel systems on any car can make you want to pull your hair out and seeing as your Alfa mechanic gave up with it..you have good reason to be intimidated.

Your compression is something to be envied though! It will be a strong motor when you get it tuned right!

Thanks Aaron -

As far as I know my previous mechanic only swapped the pump. I can't distrust Wes though. He is a legend. There is another problem here that we haven't uncovered yet. You are correct that I haven't drive the car much since I bought it. Maybe 500 miles. I'm taking it that it is a good sign that I can somewhat read the numbers on the pistons with a borescope. That's how another forum member was able to tenitivly identify the pistons. I'm sure that my new mechanic will get this all strengthened out in the spring. Unfortunately, his shop is in the icebox part of the state and it appears that we have an early winter setting in.

I agree, something is amiss. I was partly wondering if maybe the manifold itself had a leaking gasket or the throttle butterflies are off in some way.
I am not one to offer SPICA advice however.

If I were you, waiting on the mechanic, I would probably wait a few days. Read up on the SPICA system here on the board, then I would get bored and decide that I must find the problem. Even if I dont drive the car, the suspense of not knowing why my car won't run correctly would drive me nuts LOL
