stag webber mixture settings

[jimmyo06]

Some say that my Stag is running rich , as the exhaust is sooty on starting , inside air filter pan is also sootish, plugs were all sooty , but I dont think they were changed in 20 years, can someone help please?

Sooty when starting is normal maybe use less choke when starting in summer.

Soot inside air filter, strange, is engine running backwards, how many reverse gears do you have? More likely oil deposits, as I previously said alternative fuelling cannot handle engine breathing as the Strombergs do.

Sooty plugs indicated rich running, presumably the idle mixture is set ok, nothing else to do as they’re set up “to run straight from the box” as we’re told

Have you got the Strombergs? Wouldn’t take long to swap them back as a comparison..

Nice mischievous reply there !

Any carb or fuelling system fitted to a engine will need at least some adjustment to "match" the particular engine - even Strombergs ( I assume EFI will either have to "autotune" itself or need some initial setting ). I am sure the Weber comes with instructions on setting the idle speed and mixture.

I would suggest checking the carb is adjusted as per the suppliers instructions - after checking the ignition system - timing, plug gaps etc. are correct. If you don't have the instructions then contact Stagweber and I am sure they will email them to you -it should only be a case of twiddling a couple of screws no special equipment or particular expertise required.

Things to check:

Air filter is partially blocked (sooty!!) and needs replacing.
Idle mixture screws are set too far out, causing a rich idle.
Choke not retracting far enough.
Fuel pump excessive pressure.

Hi , i meant inside the pan cake filler has smokey deposts, not sooty.

Since changing all saprk plugs and leads , starts 1st time and sounds as should.

still sooty smoke on starting , which then disappears , car has been hardly used in last 20 years.

Took car out today , drove fine , gearbox changing smoothly now , but I do get a clunk on reverse?

Great feed back as usual guys

[Wheelz]

Sounds pretty good then.

Just a couple more tips:

Try using less or no choke.
Dont pump the throttle at all as it richens the mixture.

ive emailed Stag webber no reply anyone know where I can buy a filter, or can i wash the one i have?

[jimmyo06]

I am sure WHEELZ can point you in the right direction for contact number. Maybe try faceache.

according to the advert in this months club magazine the telephone number for Luke at Stagwebber is 07723 023271. As for the filter take it to a decent motor factors and they should be able to identify and supply the correct replacement

Thats correct for Luke at stagweber. Try a Mann C2536 or equivalent for the filter. A few on eBay.
