Alan,

         Can you tell what the "grit" is. Might tell you where it came from. As far as the  total evaporation, seems like you live where it's hot and at a higher altitude, right?

I call it grit? looks like a fine reddish gray powder. Seems like rust to me.

It was supposed to be 105 yesterday so that made it a balmy 95ish in my garage. Only going to be a 100 today.



Elevation is 650

thanks for all your suggestions, guys. I disassembled and cleaned the carb 4 times I think!, lost track. But was finally able to "clear the idle screw adjustment with compressed air while the carb was on the car. I would have done that first I just couldn't locate the problem.

I had to replace the other old fuel lines to get it to run clean. even added fuel strained thru a sock, trying to get things straitened out

All at the same time I was getting weaker and weaker spark???

So once the carb got strait I put a timing light on it -No advance! Pulled the distributor and checked it on the machine-no advance AND something was rattling around in there! A buddy's shop will fix that for me I hope in the am, probably a loose screw or something and will reset the mech advance.

Nothing has been simple on this redo.

Still trying to make it run again to get to the tranny shop for the AOD adjust and check.

Still trying to make it drive to Columbus

Hopefully this dist. issue will be sorted out in am and I can move on. Still a ton a stuff to get done.

Alan,

    That does sound like rust, keep watching the filter for a while, might even carry a spare element with you, if it's possible to change easily. Eventually it'll slow down or stop.

         I got so frustrated with mine I finally went and bought a new tank, I could NOT get the old one clean. Used bolts and shook it washed it out about ten times, kept on clogging up. Very frustrating.

I still haven't been able to fix it.

I thought I had it when the dist. was recurved and we found a small piece of the weld broken off, put it all back together ran great for awhile then started to sputter again.

Also I rubber hose rigged a fuel filter and temp ditched the stock one so I could keep checking it or changing it.

I don't know what is next?? carb has been off about four times now.

When I recently struggled with pump capacity - finally dumped the T-bird stocker for the Airtex 362 (428 FE) pump - I rigged up a jug on the floor to absolutely eliminate the fuel tank and plumbing as a problem source for the starvation situation.

The old "double action" vacuum pump on mine was a loser. You aren't sucking an internal fuel leak up into the vacuum port?

You installed your new tank and the outlet tube flows easily?  

Your electric booster pump isn't a suction problem is it? Does it have an internal screen?

And you've got the old style glass bowl filter out of the line by now, right?

And extended idle causes the carb to flood? or starve? You don't have a "Titanic" (sinking) float?

 I know all of the goofy questions can be annoying - got a friend with a carb you know works?

Steve, thanks for the response.

I think I have adequate fuel out of the fuel line after the filter(still may not be clean enough?)

So the carb may be dirty again.

the sinking float is one I hadn't thought of.

Gonna try another replacement carb in the am



The good news is when it WAS running I backed it in and out of the garage a few times with the new trans!

I just reread your post.

Are you saying that my stock pump might be drawing fuel back from the carb because of an internal leak? Pump is a few years old and come to think of it it wasn't used in the dyno test

I should also eliminates all the fuel line with a gravity feed system tomorrow. thanks for the help.

I was thinking that it might be posssible for the old style fuel pump to have an internal leak - that allowed additional fuel to be pulled up the vacuum line. It would make the intake system go over rich - like flooding at idle.

There is an Airtex 362 on ebay this evening: Item number: 250280280366

I finally ended up with the bigger pump and a big AC canister filter on there - rubber jumper hose to the original fuel line. Had to "clock" the pump outlet port around to the front a bit. 

I drilled out (as much as I dared) and radiused every flow stopping edge of the brass fittings. The inlet hose was sized up to fit over the end of the original double flared 5/16 fuel line. This arrangement puts out some serious flow at the carb inlet fitting (at least way more than the original T-bird part).

Good luck finding your gremlin - Its getting close on making the run to Columbus!!!!
