Adjusted the timing a little last night (it was reading 0tdc and I pulled it back to 10BTDC at 1000rpm idle) and added more ATF fluid to the carburetors. I had also apparently forgotten to reattach the vaccum advance and retard when I put the manifold and carburetors back on. Tweaked the timing [...]
I got her out of the shop on Friday and she purrs like a kitten. I spent Friday evening cleaning her out and drove to a show later in the evening. Saturday afternoon she got a new set of tires on the stock steel wheels (195 65/15). It drove a little rough all weekend until [...]
Won another zs carb on ebay for $11. Hot damn. The rebuild kit for the bypass valve on the front carb should arrive this week too. I am going to try to switch out the rear carb with one of the others this week. Maybe it\’s something funny I missed with the rear carburetor. [...]
Went out to the car again on Sunday to check out the timing and the carburetors. It is idling pretty high at around 1400rpm. The air valve on the rear carburetor is not rising as high as the front – indicating a vacuum difference? When you pull the air valve up with [...]
I finished cleaning the rear carburetor and am about 3/4 done with the front. They both need gaskets, but it looks like the needle and jet are clean now and the float bowls look to be in good shape too. The front carburetor had a ripped diaphragm (as you can see below) – pretty gnarly! [...]
In searching the web for information about the Zenith Stromberg 175 CD2SE carburetors in my Volvo, I found this amazing PDF. This is perhaps the most concise and well illustrated document I’ve seen. I think my heartrate went up a little when I found it! It gives me a much better understanding for how they [...]
I got a good start on cleaning the front carburetor this weekend. It is really gunked up – I am halfway into my second can of carb cleaner and not even done yet. The only screws I haven’t been able to get out are on the top unfortunately. I was going to cut a notch in the [...]
Jim and I went out to the car last night to take a closer look at the carbs. Jim tried to start it while I sprayed some carb cleaner in there and it backfired a few times but didn’t start. We decided to take them off, which didn’t end up being a huge [...]
