Well I got it back late this afternoon from my mechanics great honest guys been using them for years. The last few days they fixed the tranny leak, replaced the electronic ignition and replaced the fuel pump. Picked it up started like a champ took it back to work parked for a hour, took it home fired right up no problem again drove fine. Stayed home for 30 minutes fired right up then went to dinner ran perfect. After dinner came out fired right up but died after 10 seconds or so. Smelled like it was flooded waited ten minutes same thing just turns over and over. Looked around could see gas waited another hour with the air filter top off to let air in tried again same thing. Called a tow service he wanted to look and thought the gas was leaking all around the carb. I could see gas on both sides of the manifold and dripping from the linkage but couldn't see from where or why. Any ideas? The tow driver thought the carb gasket might be blown out but I have no idea why that would be he suggested the new fuel pump had more pressure then it could handle??? No idea personally what does it sound like to all you here?


Thanks for the info and help. PG

From my experience from a long time ago, flooding happened when the float in the carb pooped out. But gas dripping all over the manifold? Not sure how that happened.
 
Probably some crud in the needle/seat area...float overfills and it pukes fuel everywhere, including over the intake manifold.
 
It's very possible dirt got in the needle & seat in the card,or some rust,if it sat awhile before being put back on the road...rust can sneak thru the best of fuel filters,it is so fine..

If it sat for a long time,the float in the carb might have developed a pinhole,and filled with gas and "sunk" it,causing it to flood...IF it has a brass float,OEM floats were often foam,and those sometimes sink after they were exposed to ethanol gas used now..
 
Had a friends buddy mechanic come look it was a stuck float on the Rochester carb he said it needs a rebuild kit and showed me how to band aid it in case it happens again until we get that done next week. Thanks PG
 
Make sure you clean out the carb and all the little vents/channels. Also, if you are still running the old gas tank, pull it out and have it professionally cleaned (or replaced). Same goes for the lines on the frame. If that hasn't already been done, throwing a new rebuild kit on wont help for long.
 
He will do the carb right as he wouldn't do it with just any kit available today he wants what he always uses and I cant remember the name he said
he will remove it clean it keep it until done.
Now the gas tank is another thing as I posted in another thread it has some aftermarket tank that holds about 42 gallons which I do like and want to keep.
Who does this type of job of cleaning old tanks I have not heard of it before and figure its not something most mechanics do I might be wrong about that however.
Thanks for the post. PG
 
You could add another in-line fuel filter closer to the tank to help trap any crud before it gets to the fuel pump and carb ...

The gas tank should have a "sock" filter in it if it has the original sending unit,unless someone removed it or the aftermarket tank has its own sending unit and it lacks one..that has a fine mesh that will even trap water,so the size of any dirt or rust particles will have to be mighty small to get past it..the ones that do will get stopped in the "extra" filter in the line...

I've had trucks that sat a long time and I had to do that,and change the filter a few times ,until all the rust was flushed out of the tank..one truck I stuck a magnet on the fuel tank ,that trapped all the red silty rust and kept it from being delivered to the fuel pump and carb..

Do you have any radiator shops around you? They usually do them.
