Thanks everyone, I understand its hard to diagnose from the computer I was just making sure I didn't overlook something "easy." After all this was my first time ever opening up a carb and cleaning the jets. I'll be sure to post pictures and let you know what I find when I make some time. And yes, there was debris clogged all around the last chance filter in the carb and some in the bowl. It's a new carb otherwise and looked pretty good after I cleaned it. I took the whole carb out today and will give it one more thorough cleaning. If I'm not mistaken, there are the two idle jets, the main jet in the middle of the bowl, the primary and secondary jets, the emulsion tubes, and the other jet that sits in the middle with a tube going to each chamber. Is there anything else I need to open up? If thats not it, I'll go look in the tank, use compressed air, pressure check to see if its getting enough fuel at higher fuel bands. Can I stick the tube that goes from the filter to the pump in a container of gas and start the car? If that doesn't change the symptoms then its not clogged behind the filter right?

Ok sounds like I gotta check everything from the fuel filter back. I'm sure the tank still has debris in it based on how bad my fuel filter got and knowing it was a garaged for the majority of its life. Wouldn't I see more crap in my new filter if the problem was behind the filter? The filter has run clear now for 2 weeks on all my test drives after refueling.

1970 Datsun 510 Also when these symptoms occur, there is occasional backfire and soot buildup in the exhaust. Crash-kinda what I was thinking thanks for the gravity fed idea. Can a fuel sender get clogged? Draker-I only pulled the fuel screen where the fuel comes in to the carb in the front. Can't seem to find where this "last chance filter" is on the 32/36.

I just bought my first Datsun about 2 months ago. It was running great until I ran it out of gas and it sucked up crap from the fuel tank. So now it bogs down and hesitates with a quick throttle blip and dies at high rpms usually over 25mph. It idles fine. I have L16, weber 32/36, matchbox dizzy I've replaced two fuel filters, replaced the fuel pump, replaced the spark plugs, taken apart the carb and cleaned all the jets and the fuel screen in the front of the Weber. Where should I look next? I am by no means a mechanic but totally willing to learn, this is my first time with a carburated car and I don't know where to look next. Check fuel pressure? Look further into the Carb? Please help I want to drive this thing. Also my first post and getting frustrated because I can't figure out how to directly post pictures from my computer.
