If you follow the link that is the official VOSA manual-the same one the tester will have it should be stated in there somewhere.

So a little update....

Went to the garage this morning as he has one of my vans in for MOT too, and I went on his computer and showed him the manual in the link which he has a copy of (as do all testers I assume) and he showed me the official 5th edition 2009 emissions book and to be fair says nothing about this rule in that book.

His machine states mine should meet 4.5% CO but it\'s currently 7.5%:bandit:bandit ,so he will phone VOSA to clarify today and all should be well. Hopefully.

He\'s a chap I\'ve used for other cars for years and is very good so I\'m relieved we could sort it without any shouting!

Maybe this link should be a sticky because I can\'t be the only 1st gen owner with this problem.

If you navigate to Section 7.3 in this VOSA manual (section for the testing of car emissions),it is quite clearly set out in the flowchart there. Wanxkel engined vehicles first used pre 01/08/1987 are to be treated as pre 1975 vehicles and are Visual Test only. All as Carl and others (and my own MOT tester) say.

Interestingly VOSA have a very good helpline Number which I\'ve used on occasion. Very helpful people there and we all agree your tester is wrong Tim, no doubt about it.

Mine was checked, only out of curiosity, figure was similiar to yours I think...

He did say it didn\'t matter, but he\'s been MOTing since these things were new...

Thats what I showed him when I went there this morning and he produced exactly the same chart from his paper manual so happy days.

If any of you are familiar with Peter Kay standup material then this morning was akin to the biscuit in the tea sketch just swap biscuit for screwdriver and tea for Nikki and you get my drift. :Giggle

Thanks for your help everyone.

Really miffed now,after all that he went on holiday. I had to source a caliper before the retest could occur which happened today so his 2nd in command went ahead but emissions tested it anyway and leaned out the mixture to get it through the 3.500% threshold his machine stipulated. Well I presume the mixture has been left at the setting it was adjusted too so will this affect my engine in any negative way...

It\'s only mod is airpump and thermal reactor removed replaced with header.

turbotoaster · August 06, 2010, 06:59:29 PM

hell yes it will effect it, get it changed back to what it was before you give it any stick!

captainbizzaro · August 06, 2010, 07:05:57 PM

Thats what I thought-he said he only screwed it half a turn so i\'ll be turning it half a turn back again! I just wasn\'t sure how lean he\'d have had to do it to cause any damage when I get all enthusiastic.

I\'m not sure there\'s a problem here.
Both the old \'Janspeed\' and the \'Double S\' instructions for fitting a stainless exhaust to the standard 12A state as the last step:- \'Reset Idle Mixture to 3%-4.5% CO at 900 rpm\'

So I think you might have got a free reset here Tim.

Also I think the factory setting was originally a tad rich to allow for full afterburn cleaning of fuel rich gases in the Thermal Reactor.

Any other opinions as I don\'t want to spout away and have my theory be wrong?

Further thoughts for discussion:-

The Idle screw on the Nikki carb only alters the Idle mix, presumably to prevent pedestrians dropping dead from CO poisoning when passing queuing cars in cities?

Apart from all its complexities the Nikki is a traditional fixed jet carburettor, i.e. with pre-determined mixture at various throttle openings, so I don\'t think that altering the idle screw will change the higher speed running characteristics in any material way.

Am I right?
