Hi

The second photo looks different, as though the choke bar may be lifting the piston and needle for more fuel (as it would if choke is pulled out), though it's proberely the angle of photo.

If not on choke then then the bar is not in contact with the piston and piston should be resting on the bridge/body of carb (also the bars should move together, so check the clamp connecting them is not loose)  .

If running rich and mixture screw/jet is set right (though hard to determine if over fueling for another reason) then other main reasons for over fueling are sticking needle valve. punctured float, or floats set too high (though last one unlikely if was running well before).

You maybe know this stuff, though, thought I would mention it.

Cars that have not been used much or neglected a bit with maintenance can need a bit of de- bugging.
  

Good luck with it.

well the choke looks like its working perfectly in your pics, did the other carb behave the same? While you've got the airfilter housing off you could try lifting each of the pistons that you can see and let them drop back down - there should be resistance to lifting due to the damping oil in the top of the carbs then they should drop back down smoothly and positively.
I do wonder about your battery/dynamo cos normally if theres enough ummmmph to start, the engine will run ok with the dynamo supplying the system. The battery certainly shouldnt go flat after a failed start or two and of course once started the ignition light should go out.....

Quoted from JohnD
JJ,
Disagree - read my post 28, where I copied the instruction from the original manual on how to secure the steering column impact clamp.

The tightness of the grub screw is determined by tightening that, NOT the two bolts that secure the clamp on the column.
And the original instructions specifically say, that the grub screw should be hand tight, without bending the Allen key (I paraphrase).

This is exactly NOT what you suggest.
When two "experts"  (has beens, under pressure) are so diametrically opposed, perhaps the Court of CT should decide!
John

Ok. Its a bit off thread. Loosen the grub screw. Locate the shaft flat bit, tighten the 2 nuts/ bolts to correctly align the shafts. Tighten the grub screw to lock the sliding shafts. Tighten the grub screw lock nut. Simple!

Cant see from the pick which carb that is, nor do i know a lot about Vitesses,
but when you pushed the choke in, did the needle resit correctly? Feel underneath the carb if there is a piece of red plastic just push it upwards, it might just spring up seating the needles correctly. This happened fairly often on my spit with SU's, other versions might have different set up,  Sorry that I  am not very confident (or convincing if you want)  in explaining what to look for without having the thing in front of me....

I'm a little scared of carbs, to many little bits! Something i have to get over.
I'll go and have another look with your comments in mind.
I have noticed a bit of a leak on the right hand carb.

Another possibility is that the needle valves inside the carbs are leaking a bit so the float chamber level increases.  This will make the car run rich even if the choke is off.  This shows up much more at idle as the engine takes least fuel so the rate of leakage exceeds rate of use.

If it's a small leak then it'll just make the car run rich at idle after a few minutes, if bigger them it will go on to flood out of the overflow drilling on the front face of the carb and into the airfilter.

This is a fairly common Stromberg CD foible and can be due to just tired needle valves, dirt or excessive fuel pressure from a dodgy modern replacement pump.

The Strombergs are the very early ones (as would be expected on a 1600) with a rather primitive choke arrangement - but they are also the simplest.

I think that's it!
The right carb is wet on the bottom.
I've driven it to the garage down the road after looking at it for a long time with a screwdriver in my hand.
I bottled it.. I used to clean the jet on my vespa on the side of the road regularly.
Oh the shame.
Please don't drum me out of the club!
Thanks again for all the help!

I talk to mine, too.

Tessa also had problems with the float valve on the front (right hand) carb after I fitted a new fuel pump. It is a common problem, leading to really poor running just like you've found. Tessa's wasn't bad enough to stop her completely but possibly only because the affected carb was set rather on the lean side.

It's great that you've (hopefully) identified the problem and can get the garage to fix it.

Hi

From my experience, if it's wet at the bottom only (just the jet holder) then larger O ring between jet holder and float bowl failed, or small O ring between jet and jet holder. I think this is just leakage rather than flooding.

Float bowl gasket leakage will show fuel from below the float bowl gasket and would not be cause it's flooded.

Needle valves sticking or not seating has shown fuel sitting on the bridge (where the piston sits), though more extreme flooding it will come through the upper hole (breather/overflow?)on the right hand on front face of carb.

Had some experience with flooding on my vitesse, though not an expert mechanic at all. Aside from the springs etc around the spindles which are a bit more fiddly (take photos, refer to diagrams) which you don't have to tamper with to sort flooding and most things, earlier Strombergs are very simple with very few parts.

Good info on the web about them.

Hopefully not overloaded you with info.

Cheers, Dave
