i have a 850 double pumper and the gas is shooting out of the tube that is cut at a angle in front of the front barrels. i thought that this meant the needle was stuck so i replaced it well still doing it. i cant get it started casue of this. with the motor off i took out the bowl screw on the side and gas came out so its filling the bowl. i banged on it with the handle of a srew driver and still nothing. i cleaned it all with carb cleaner but still nothing. any suggestions thanks

 

Do you have both an in-line filter and the screens at the bowl inlets? If not, you could just be putting more junk into the needle/seat.

Check for float problems such as sticking or full of fuel.

Really dumb question: Did you adjust the float?

 

i checked all my filters and such and nothing was missing or anything like that. i cant get the car running ot set the floats, if i turn the pump on it just shoots gas out, i men big time shoots it out. but like i said after i turned off the pump i did take out the bowl screw and gas came out, not so much that it woudlnt be normal. i will check everything again just to make sure. thanks

 

sounds like a bad flot. remove and inspect

 

took the float apart looks fine put back together and cleaned old needle and put back in still dumping gas out of tube any other suggestions

 

Brass Float: remove the float and scuff the brass surface up with steel wool to remove fuel glaze. Coat it, using a brush with Seal-All

Don;t want a thick blob of seall all on it just a nice thin even
coating over the whole brass float.
especialy the soldered seams. Let it dry overnight.
Make sure the float arm is not bent. Compare with the other one.

Reinstall and replace the needle and seat assembly with a new one.

With the fuel bowl held upside down in your hand adjust the float so it is level and parrallel with the floor of the fuel bowl.
Then turn in the fuel inlet nut about 2 turns so that the float is just raised from parrallel as you look at it upside down.
This is a good static setting that will allow you to start the car.

Since you've flooded it good a few times. you're bound to have fuel washed the oil in the pan. Change the oil.

 

yeah i did pretty much everything you said about setting float and all except the sealer stuff. i did change the oil but i might have ot change it again. could the regulator have gone bad somehow, its just a holley regulator. thanks for info

 

You should be running something better than a holley regulator on that motor anyway. I checked it out at Capitol a while ago, not the optimal setup. May want to consider the polymer floats. Would be a good time to put in a set of jet extentions too, the car looked like it hesitated a bit. I have a set of jet extensions you can have if you want.

 

Hey dialed-in if you saw it ran mid to late Nov. then yeah it fell on its face big time off the line. that run was with a brand new trans and i put a carb spacer on it then to, so i really never got to adjust on it and besides i was cold that and didnt feel like standing around anymore. i've got extensions in it and was thinking of going ot the polymer float just becasue well it not running right now and its a good time. i really watn the magnfuel regulator for it, i have that pump filter set up under it so was going to get that. what set up would you recomend? thanks for the help.

 

Man, holley regulator with magnafuel pump setup. I wanted to go with their pump and filter but couldn't justify the cost for my little motor. I'm a fan of their pumps but have had a couple problems with their reuglators. My buddy's Nova went through two of them, diaphragms took a dump and they semeed to creep a lot. I like Aeromotive regulators. BTW, I looked and I have a set of Quick Fuel polymer floats. As for the bogging it could be either the squirters or the pump diaphragms maybe a little too big, but from the sound of your original post, your floats are probably off.

 

i have been wanting to check the floats but scince i cant get the car started without the gas shooting out of the tube i cant check them. i think the problem with it falling in its face was the squirter, i did chagne the jets a little smaller so i might need more squirter, plus i put on that spacer.

 

Best bet is to pull the bowls off and clean the seats again and then set the bowls like F-Bird88 said a while ago. That'll let you start the car.

 

ok so today i turned on the fuel pump long enough to see what the psi was on the gauge and adusted it back down to about 5 psi just to get the car started and burn some of the gas out of the carb and i had it running and turned on the pump and gas started shooting out of that tube again. of course i turned it off and reved it up to burn any gas the went into the motor and now i am back at square one i guess. the bowls are set and brand new needle and seat are in the front bowl. any suggestions?

 

Something is holding the needle off of the seat. It's either interferring with the float, or the needle.

 

ok guys i hvae replaced the needle and seat with brand new ones and i have replaced the float with a poly style one. i have adjusted the float with the bowl off the carb and upside down, and still gas shoots out of the vent tube on the carb. as soon as i get it running and turn on the fuel pump it starts flowing out. any ideas any suggestions?

 

Bench test the fuel bowl/ float assembly to ensure it will control fuel flow with movement of the float.

May be a casting flaw allowing fuel around the needle and seat assembley even thou the float is closing the needle and seat. You are using the O rings on the needle and seat right? You have the right part number needle and seat?

Remove the fuel bowl from the carb. Hook up the fuel line to the fuel bowl fuel inlet.
Flow fuel thru the float bowl into a bucket and see if you can control the flow with the float by moving the float up and down by hand.

 

needle and seat are right for the carb and yes i am using o rings for it. i will try to to do flow control thing while bowl is off carb and see what happens. i just dont get it car has been running fine and now all the sudden i am having what seems to be a needle seat problem but i guess that not it. thanks for the help so far anymore will also help.

 

OK

YOU HAVE TWO MUCH FUEL PRESURE THAT IS FLOODING YOUR CARB OUT.

i JUST WENT THROUGH THE SAME STUFF LAST SUMMER WHEN MY REGULATER FAILED. i REBUILT THE CARB AND CHANGED THE REGULATER, AND IT WORKED FINE

LATER AN D

the regulator is fine i changed the pressure up and down to see if its working and it was. i left it on about 4 just to make sure that it wasnt flooding it out. could it still be bad even though it works, if that makes scense?

 

possible the gage I switched a tpi car over to carb and still use the orginal fuel pump. I had to get an adjustible fuel pressure regulator for my application and a gage. If the regulator is working properly the try a different gage, maybe the gage is reading wrong. My regulator failed and let the entire pressure of the puel pump flooded the carb thoughout every part of the carb forcing the needles open and it used fuel out of the tube you discribed.
Let me know what you find out and I will do what i can for you
later and
