UPDATE: Possibly the Culprit on Drag~N~Fly

I have about 1/2 gallon left. I thought about testing it with a Hydrometer to find out what the specific gravity is on the fuel we have, test some straight gas and see what it is.

I KNOW the fuel is a major player in my problems cause we busted it off and it cleaned up like it was supposed to. I am nt hauling the car to Austin unless I get in it and physically test the system. I plan on doing that over the weekend, weather permitting. I hate to say that it is 100% so soon.
Dad was tweaking on it a little earlier....he called and had mom holding the phone to let me hear the motor.....he's ate up.
I do know that it all makes sense now looking back.....

 

I hope your right on the fuel problem. That car is just COOOL! I had a simular problem a coupla years ago with a new/fresh engine I did for my modified. The car sat all winter with almost a full cell of cam2, I changed the engine out fired adjusted valves ect sounded bad ***. Drove on to the trailer smokin the tires, Unloaded at the track after a hunred and fifty mile drive and gas slosh around. (enough ta mix the gas and humidity) Wouldnt turn over four grand, Sounded like a mul***ude of shot gun blasts under load. Took about a week ta figure my mistake. Cal

 

This one was popping it was so lean......

 

Root, Why don't you get a degree wheel and a dial indicator and find out what the specs are on that cam? Did you degree it in when you installed it? I know you can degree a cam without the specs by just splitting the overlap and using that as a base but if you had some hard specs maybe you could match it with an old catalog or call the manufacturer and zero in on the grind.
BTW we used to split the overlap then advance it 2 degrees on small block Chevys. This where most grinds will come into their own on this engine.

Really ****s about the bad fuel!

.....in high school, I had an 8' hydroplane with a 10hp Merc Hurricane. I would run Sunoco high test with a little methanol thrown in and hot plugs. In a tear down over the winter, I noticed little pits burning into the center of the pistons. Time to sell.......... (ran great though!)

 

Roothawg somethings to check, make sure your ****erflies are all even, I set mine at .004 but I don't know if that would be the same for blackie carbon.Also if there was corosion on the pill then there is bound to be some in the nozzles, I would remove them and clean them out. I had the same problem with mine once and did the same thing, I thought it was the pump going away but it turned out that I had some bent ****erflies.I have also had clogged nozzles cause a lean on some cylinders bug. It causes it to lean on the clogged cylinders and be real fat on the others cause the fuel pressure goes way up on the ones that are not clogged.Also I have had foreign objects get into the by-p*** and cause a simalar problem.A clogged distrobution line from the metering valve would cause it too.Sounds more like water in the gas than methanol.Good luck I hope to see you at Temple.

 

Oh and check your vent on the fuel tank, mine stopped up once and really screwed me up for a day or two!

 

We pulled the nozzles at the track...they were OK. We also pulled the cap while it was running to verify that it wasn't a vent problem.

I am going to pour some of it into a gl*** container to check for the water content.

The ****erflies are ok, we use a piece of paper to set them all the same....just a little drag on em. Just right.

Crazy stuff.

 

I hope you're right, Root. That would be a really EZ fix, provided there aren't any burnt pistons. Crossed fingers..

 

Sounds like you got it under control, I hope to see you at Temple if you can make it. I am gonna try to get some more FED's to show up. My pump went away a couple months back and I just got my car going again. I am going to my local track to make some p***es tomorrow night in preperation for temple.

 

Went by tonight and talked to the guy that sold me the fuel. He showed me the containers he had bought recently. They look a lot different. They are sealed and look more like a factory type deal. The 5 gallon pail he had sold us weren't sealed and the buckets looked old. He said that he had about 4 of the old styled buckets that were different.
I think that his vendor may be trying to pull a fast one on him.

He has offered to take take the little bit of fuel we have left and have it tested by someone other than his salesman....and give me one of the sealed 5 gallon buckets.
It may have just been a fluke deal.....I just hope this was the worst of it.
