WAY TOO MUCH FUEL

[papawfalcon]

My son put a 78' 200 in a Ranger weve tried 3 different carb.. All 3 are dumping Way too much fuel. The last one we tried was off of another 200 thats in his 63' Falcon that runs great. Also tried using a fuel regulator and no such help....
Any Clues?????????

What fuel pump are you running? If the truck was originally FI, and you retained the original fuel pump - that could be it.

X2 way too much fuel pressure, would take a special fuel reg. and or a return fuel line to tank might help bypass excess fuel and lower the pressure.

Right now the engine has a new stock fuel pump for a '78 Fairmount. the fuel line comming in is in a one gallon gas can.So the fuel tank is a gas can.

 

[bubba22349]

Than those carbs need work or rebuilds check float level and needle and seat, also check to see that float is bad IE too heavy. Good luck

I can understand that for two of them. But the trird on is off of his 1963 Falcon with a 1978 200 also and that car runs daily and runs great. We are thinking the new fuel pump is bad and the parts store has ordered a upgraded on . THANKS FOR ALL THE HELP. We may also get a carborator kit.

I'd get the carb back on the '63 and check how the arm on the f. pump hits the finger from the motor. Some here have said there's a mismatch on some & I think they bend the f pump arm to hit it more squarely.. or is that not the issue w/the mismatch...not enuff fuel instead w/this mismatch?

 

[papawfalcon]

New fuel pump new carb and no change

 

[bubba22349]

Do you have a fuel pressure tester or gauge?

 

[papawfalcon]

Checked fuel pressure right at 8lbs.

 

[bubba22349]

You need to regulate it down to about to 5 or 4.5.

I once had the valve cover opening my throttle on my 1100, another time I had a hose clamp messing up my pump shot.

I highly recommend looking around the carb and what is touching it, or anything that might be interfering it. I don't think a fuel pump can do what your suggesting... but this is just my opinion. seems everyone else is going fuel pump.

edit: another time I had the gas arm not come down all the way and rested on the header. that kept is on high idle... in the end it was everything around it affecting the carb.

 

[papawfalcon]

dont understand will no idle.... WHEN it starts carb has to be wide open and might be reving 2000rpm and the second carb it let off just a tiny bit it shuts down. replaced pump and carb on 63' and runs perfect.

Consider a vacuum leak. Also, are the carbs SCV and trying to match up with a later model distributor? Just a shot in the dark here.

 

[papawfalcon]

Checked over and over for vacume leaks. All carbs and pumps are either 78 or 79 200. Recheck timming several times and its always right at or very close. I did notice coil didnt seem to be firing every time so after work headed to get new coil

 

[vssman]

I've seen a sticky PCV valve cause the car to run as you describe. Try disconnecting it and plugging the line with a bolt.

 

[papawfalcon]

Now the darn thing wont start at all... acts like its out if time??? Very hard to to turn over. Checked timming several times. Battery has full charge???? Any options

 

[chad]

"...wont start..."
we don't know the symptoms
Ja buy & just put in the new coil? There wuz a prob there...

 

[papawfalcon]

I didnt have a coil for it thats why i bought one and itsgot fire

 

[chad]

"...itsgot fire..."

(Oh, OK, thank you.) good, alright - all the way from the coil to the plugs? I wuz thinkin it might B sompin W/the dizzy. Is it strong enuff? In the right "order" ie U were sayin sompin bout timing may B off? 'splain please (yeah I'm Ricky Ricardo the second).
