Carb Trouble

[jaredts]

Its a good idea to get the fuel line off the intake and anything else. It will eventually rub a hole and start a fire.

Thanks for the advice, that makes sense.

Yeah well I had it running with the new carb for about 2 weeks but let it sit in my yard for a weekend and it wont start.
I know theres fuel because the guage still changes when I hit the switch it just doesnt change between tanks so I quickly switched the lines over, But ya il put some more gas in the tank and see if it gets any, and Il try the idea of cranking with the line off into a container.

Also just wondering for something else, Does anyone know if it would be possible to put an electric choke on a stock rochester carb that has a vacuum choke? Thanks for all the replys

If the carb is correct for the year it probably has a hot air choke. It is possible and common to get a coversion kit to convert it to electric choke.

[discot315]

Yeah im pretty sure the 1980 carb was a hot-air choke, had a line going into the intake manifold. not sure what my 77 carb is. Where could I get a kit to convert one to electric?

[1980c10]

heres how:

 try a search on summit.

it's easy to rule out/or in a choke problem.  If the engine is cold and hasn't run any, the flap should be closed after you activate the throttle.  If it has run a few mintues, the flap will be open.  

Even if it is slightly open after punching the throttle, when it is cold, it will be extremely hard to start.

Thanks. and ya definetly not working then.
I took the fuel line off at the carb and put it in a bottle and cranked the motor and theres definitly gas getting to the carb just not through it..

Also could anyone give me any info on these carbs I have? I have a few spare carbs around and actually looked at them today and am not sure about them,

One looks like a electric choke and the other one I think was off a 74 chevy.

the top pic looks to be electric

the next pic:
Uses a bi-metal spring for the choke, this is located on the manifold connected by a rod and would be considered a divorced choke. you would need a manifold that accepts this type of choke and this can not be converted to electric.

another newer type is the heat raiser tube type chokes, which have a tube going to the intake manifold to the quadrajet choke housing. This uses the same principle as the ealier type but because of the location of the bimetal coil this can converted to electric with a kit. When converted this does not require a manifold designed to accept it.

I belive there are a couple of electronic versions; non computer and computer and the '82 may have a provision for the esc, hopefully someone here has a little more info on this.

Oh ok ya that makes sense, I couldnt figure out how the choke worked on the second one. the first one does look electric but it has a wierd connection thats really big and no spot for a ground wire.  not like other electric ones i have seen before

A lot of times they are grounded to the carb itself.

If you'd like to buy the connector for that:

I realise you're in BC, but I'm not sure what you got there in the way of parts stores. . .perhaps a Prince Auto or something?

[discot315]

ohhh ok ya that definitly looks like it would fit. Theres 3 different part stores in the town here maybe il search around and see if its available to get then, thanks!

[TexasRed]

You could also take a connector that accepts the blade male and cut off one side of the part that folds over and leave it open.

[discot315]

yeah true, I might try that to see if it will work
