Rough Running w/ Dual Carbs, And now low fuel pressure too. Options

[Craigers17]

So I've been trying to track down a rough running issue with my 2056 w/ dual 40IDF's. It has not been running well for several months, and has had spells of sitting for a while. When these issues started, probably 9 months ago now, I changed out the old fuel filter and relocated the pump and filter to the front and upgraded both to the type that Tangerine sells. I also took that opportunity to install a stainless steel line and all new rubber lines. (the problem existed BEFORE I did all of this)

Recently, in the last week or so, I replaced both manifold and carb gaskets. I haven't actually opened up the carbs yet, but have cleaned all the jets. After this work, I had it running great for about a quarter mile, and then started backfiring and bogging down. I have a fuel gauge and also noticed that it is now only reading about 1.25 to 1.5. It normallly sits around 3 consistently. I suspected maybe I had a fuel line that was kinked under the tank, so I pulled it and they are fine with no leaks.

I am thinking that the fuel filter may be clogged after having sat dormant for so long, OR, I might have some clogging going on in either my fuel "T" splitting the carbs or in the "T" that contains the gauge. My only other guess is that something is going on with the floats. I know this post is a lot, but if anyone has any ideas, please feel free to chime in. Thanks!

So I wanted to post an update on this just because it's so bizarre. So I haven't touched the car in about 2 months....busy with work. In addition to the carb issue, my turn signals weren't working so I bought an E26 flasher relay from Spoke. Since I figured that would be a quick fix, I installed it this morning and the turn signals are working again as expected.

Since I was already in the car, I figured I'd give it a start since it's been idle for a couple months. It cranked right up and was idling great. So, with little optimism, I figured I'd give it a spin for a few miles to see how bad it was going to run. To my surprise, it ran great, but I needed gas so I got a few gallons and went to pick up some groceries. Ran it for about 10 miles. (no bogging down, no backfiring, complete power was back)

I did have some very small issues, but it mostly ran great. I'm pretty sure the issues I did have were due to the linkage on the driver side carb which isn't returning 100% correctly....the hole in the throttle lever that the shaft goes through is wallowed out a bit and it's creating a situation where the lever isn't returning as well as it should( I have a pulley system linkage & that's why that's important). That said, overall the car is running great.

The only thing I changed was the E26 flasher. Additional information is that I changed out the fuel filter the last time I fiddled with the carbs, but still couldn't get it running correctly. My thought there is that, MAYBE, there was water/mositure in the old filter and possibly the pump???? After having replaced the filter and giving it 2 months to "dry out", the moisture issue corrected itself???? I'm basically grasping at straws because I can't figure out why all of a sudden, it's running flawlessly.

Well, for anyone that cares, that's where I'm at. Thanks again for the help!
