Tazz 2E , high fuel consumption

Postby Sean007 » Tue Aug 24, 2010 11:22 am

Howsit,
The wifes tazz seems to be running a bit rich. I can smell strong petrol fumes from the exhaust. Its basically just got a 50 mm free flow exhaust and no other mods to the carbs. I've checked the air filter and plugs an theyre all fine. The car does not seem to jerk or splutter but the fuel consumption is a bit higher than usual, So could it be the carb is acting up ??
The exhaust colour is black , even on long runs., fuel consupmtion = 550 kms on a tanK, which is about 11 .0L per 100kms
Any help great appreciated,

I think CO's need to be set.

definitely sounds like the co is out.............basically the air/fuel ratio, should be set between 1 and 1.5 using a co metre.

On a tazz with normal driving you should get about 700km.....

and the exhaust not necessarily going to be a different color due to unleaded fuel......

700km on 50litres of petrol?

How do you adjust the afr on the 2e? screws on the carb?

Yep bru , the adjustment are made accordingly to the co metre , which has attachment thats inserted in the exhaust to give a reading & adjust from there on :thumbright:

What causes a carb to start over fuelling?

very difficult question.........but u definitely know when it is over fueling, just get someone with co meter to set it up, will make a huge difference and also engine life will be pro-longed.

IF co's are out can cause major issues, especially when it is too lean, valves tend to burn quickly and then you got bigger issues, cheaper just to set the co.

and yes, 700km from 50lt..........sometimes more than 700km, i know a guy that does tongaat to durban central daily and after we set his tazz he was doing closer 800km......he was guaranteed his 700km, that is quoted directly as he told me.

Does the 2E have a CO sensor?

But does it have a co setting, or is it just screws that you turn? I mean there is no sensors or electronics, it’s all mechanical? I think setting the thing if it’s out is fine, but how does it go out? I would rather say the carb needs a overhaul. Or your air filter needs changing. Don’t just adjust the thing, strip and clean plus replace :dontknow:

the co on a tazz is set by adjusting the air screw on the carb..........you can only get it correct if you have the co meter to read the exhaust emissions.
