Volvo 340 1988 1.4 B14.4E Running bad and stalling

Post by sqlurt » 05 May 2013 10:12 pm

Hey, a new guy from Denmark here, (these cars aren't hanging on trees nor are the parts for them)

My Volvo 340 1.4 B14.4E with 4 gear manual gear box is acting up, and the idle is really bad, ive basically checked everything, im not too familiar with carb engines, so i was wondering if you guys could help me,

Here is a link to the video showing how its running, and here is a list of what i've changed.

http://www.youtube.com/watch?v=P1R1lBnphC8


Spark Plugs
Fuel pump
Tested Vacuum Hoses (non were leaking)
Ignition Coil
Crankshaft sensor
Air filter.

Im almost about to give up, and what would be best, buying a used carb or buying a Rebuild kit? and as far as i know its an 32 DIR weber carb twin barrel.

Thanks guys

Air leaks are the most common problem along with sticking floats

Cheers mate, i read most of it, but i just wanted to see if someone could pin point an obvious fault, because it doesnt seem like it has any air leaks. will check the floater tomorrow

Or with rusty petrol tanks, even with a filter, the really fine stuff still gets through....

If you have had a good look at all the pipes a hidden problem can be the carb breather inlet at the bottom of the carb. Its a pipe the comes out after the butterfly valve and connects to the valve cover if too much air come in here it will means not enough suction through the carb. Temporarily block this pipe so the carb is sealed, open breather won't matter for testing, if it sorts out the idle there is not enough of a restriction in air flow in the T-piece, it should have a restriction in it but if replaced with an older part may not have it.

Spraying with release oil like WD40 will seal up small leaks temporarily, so thats worth a try as well. You are looking for air comming after the carb so check the carb base, manifold, vacuum servo pipe, ignition advance pipe etc.

If the restricter isnt in the Valve cover hose, is there a way of getting that fixed by buying a smaller hose or do i need to find a replacement hose with original restricter?

No, you just need the restrictor piece. Think it's a Renault part no. Mac?

Sounds alot better, fairly steady now, just low rpm I think. With your air filter I think it means the restrictor is part of the T piece, or maybe the pipe is small bore. The earlier models with tube air filter had the restrictor in the pipe. You can gain the same effect by rolling up some paper and partly plugging the hose, but obviously hard to get it as orginal, and you don't want it sucked into the intake. Another idea is a say about 3mm of 4mm push fit tubing, the hard stuff for small pneumatics, push it into the pipe.

Anyone know what size hole we need?
