Carb dampers

[coxy123]

Spitfire is missing slightly, mainly when you take foot off of accelerator then on back on again.

Is this to do with dampers on the carbs, if so, how full should they be and with what?

Thanks in advance Coxy

I would think a miss or stutter is more likely, plugs, points, leads etc.

I unknowingly ran my Vitesse which has Su's fitted, with hardly any oil in one dash pot. Ran well, only sympton was a rattle, eventually traced to the front carb.

Thanks Mark. i'll have a check, although i set them not long ago. Maybe I need to run car for a while, its not really been anywhere for 18 months

I had a similar problem with a miss under load recently on my gt6, similarly the car has sat for the last couple of years, occasional start up, new plugs and points few years ago, but no miles. I assumed the plugs had got moisture in them and deteriorated. Removed plugs, surprised to see no's 4 to 6 were sooty, cleaned up and runs fine. Must have been initial start up on choke had Fouled the rear three plugs.

Worth checking you have oil in both dash pots though, for overall performance.

Manual says engine oil. I put a tea towel around the neck of the carb, fill up the dashpot and push the piston back in catching what oil gets pushed out in the towel. Then hide towel in kitchen.

Then you hide where? 👁️‍🗨️

use engine oil fill to  near the top of the inner tube 

the damper should sit in the oil and needs a light push down to engage the threads and lightly nip up the top cap 

so if the damper sits about 1/2 "  proud after a top up  thats about full ok 

its an important little mechanism to act as an enrichment devive for solving flat spots on  acceleration 

any hic ups from off power toon power relies on the damper working as a damper 

therre are cases of latest plugs fouling after choke and they dont recover well 

never use any plugs with an R in the suffix if using std  HT

Don't have to! That advise is for you poor souls with significant others. I have no such encumbrance. 

But a lot of dirty tea towel.

It isn't the making it's the drinking that causes his 'condition'

Funny you should say that, I've got rid of my bottles, I thought with my pension I can afford to buy beer! But now they're talking about doing away with the triple lock. On top of that THIS has been the situation in Waitrose beer isle since last Monday.

I think I made a mistake

Mmmmmmm... Moretti....

Looks like our shelves over here, we have the EU, shortage of lorry drivers, shortage of shop staff and the warm weather all competing to keep the shelves empty. Not something we can't overcome, tho.

Hmmm?, An old Calorifier and a lot of Copper pipe, plus some Potatoes?.

Nah,

Put the beer in the freezer, the water content freezes and what remains liquid, is very nice.

And I'm debating which of the two local artisan breweries to go to to stock up. One is very close, in the direction I go regularly to shop, so is convenient. The other further away, maybe 30 minutes instead of 15, but is a pleasant drive in the Triumph.

Life is so hard and full of complex decisions

Yes got a reprieve due to Covid!! No more sitting in wards watching television with the sound turned off.

Celebrated by going out last night and indulging in Mourne Mist, my fav beverage of the moment. I reckon a few bottles of their stout would have me darlin mother up and dancing again.
