High fuel consumption

[marquisman]

thats why i love the land of carbs! no electrical shit

[gadget73]

How does a leaky needle-and-seat cause excessive fuel consumption? Does it allow the level in the float bowl to get too high and force too much fuel through the main jets?

it dumps out the bowl vent and runs into the carb, but yes.


Murphmobile: no O2 sensor on a canadian 2v carb car that I'm aware of.

[marquisman]

none what-so ever lol

[Dave84]

yes no o2 sencor

Well she is getting worse. this morn fired her up it went on high idle so i let it run while i cleaned the snow of, well it slowly began to start running relly loppey, sounded like it had a pretty whiled cam in it, well then the black smoke started and she stalled, was relly hard to start back up, had to put my foot to the floor, so it was flooded pretty bad, and when it did start at full throttle it was probly only at 1500 rpms, and running very very rough, with extream black smoke that burnt your eyes on contact, oh it was bad...it continued to run relly lopey, but i started driving and it cleard up, till i got to tim hortons drive thru, it ran fine then all of a sudden starts running rough with the black smoke. so when i left there it cleard up again, until i got to about the 4th stop sing, then it stalled as soon as i took my foot of the gas, fired back up, but not with out a struggle, well i go to pull out sputters and stalls right in the middle of the road, starts back up with a bit of a struggle then runs fine again the whole way home, it almoast sounds like the choke to me, but i checked it all out, the linkage moves freely, and the choke is opening up all the way after the engine is warm..last week i lean'd out the carb needle valves but still is fucked. i cant afford to buy a carb kit right now, any ideas of how i can band aid this for now before it stops running all together?
I also put silicon grease on all the contacts on every wire conection in the engine compartment, that seemd to make it a bit better having good contact.

Shoot, sounds like what this '81 was doing when I had to struggle to pull it into the garage!

have you actually checked mileage, or are you using the guessed distance per inaccurate needle movement?

While towing it got 100 miles in the first 1/4 tank, of course once I shut it off and it cooled over night it only had 1/4 of a tank left. The fuel level indicator is very temperature dependent since it is based on resistance. Current flows through it for a while and it warms up, which is why it always reads lower when you first turn the key on than it does 5 minutes from then.

Could you swap the carb off of your Vic onto it or is that a different piece altogether?

mine is the oposit from that, when i first start it it always reads higher then it normaly is then goes down

[marquisman]

your car is doing what mine did when the VV carb shit the bed(was a good carb for 23 years) but it got worse and it was a gunked up since it was never touched in its lifetime, so now it has a 2150...take that carb off and apart and soak it in carb cleaner and rebuild it and make sure the float is set right.

[gadget73]

need to rebuild the carb. its leaking internally somewhere, which is what the black smoke and poor economy is about. Probably the accel diaphragm tore or the needle seat is sticking or leaking. Not much of a way around doing it properly, once you try and take the thing apart the gaskets are most likely going to rip and you won't be able to do anything with it. If they rake you over the coals that bad in Canadia for the kit, maybe you can order a kit online from a US seller and have it shipped in.

[Dave84]

well i can get a new kit for around 50 bux, so soon as i get the cash i will get the kit and redo the carb

great, we have a yank who is lovin our coffee!:p

[1987cp]

Who said anything about coffee? I can't drink most stuff from restaurants. Too strong and no real flavor. The dehydrating and jittery effects would probably be more fun to come by by washing down a No-Doze with a beer. :p

whoops, getting OT in tech again.


So is excessive fuel consumption also typical of a 2150 or Holley 2V that needs rebuilding?

[marquisman]

either excessive or minamal consumption works both ways, but usally when they start going, they leak and run the motor rich, that what iv always dealt with.
