Tham removing the cap is not hard even without removing the carb , just remove the air box and then you will have enough room in the back of carb to remove the plug with appropriate wrench then you can remove the cap .
But if your are going to change those orings on main jet it would be difficult with carb in place it is possible but you should take it slowly and very carefully .
You should remove the idle screw totally , remove the main jet plug then just under the idle screw and on the carb body there is very very tiny screw which holds the main jet in place by . There is a groove on the main jet which is aligned to the body of the carb and this screw hold it .
Be careful removing this screw as this screw is very tiny and there is also very tiny gasket under it .
When loosening this screw you should also have an eye on the main jet as when this screw is fully loosened the main jet may jump out cause there is powerful spring behind it .
You can do it in place as i have done it many times but you would better doing it off the carb and remove the carb which is lot easier for you as you have not done it before .

ThamAs described by Amir Khan, if you are just taking out
the main jet for the O rings, it is not complicated.
(see below).
The only thing I foresee is that it could be strenuous
for your back if you are doing it without removing
the carb from the car (which involves hoses, linkages etc.).
Re-edit: on examining the space, I don't think there is a
possibility of removing the tiny screw without removing the
idle screw above it. Hence the idle screw may have to be
marked before removal.
Thanks, Amir Khan and Albert.
Yes, that's the trouble with these front wheel drive cars.
Extremely difficult to access many parts of the engine,
especially the carburettor.
I only managed to see that tight cap covering the main jet screw
with a mirror placed behind it.
With a rear wheel drive, you can see everything and easily
take out all those screws from the side.
It's almost impossible to see anything, let alone take out
all those tiny screws, gaskets and springs with the carb
facing that tight space with the firewall.
The moment you loosen it, the tiny o-rings, gaskets and spring
are all bound to fly out behind to nowhere.
It seems you need special tools to remove the tamperproof caps
for both the idle and main jets ?
The seem to be three o-rings.
What are their sizes and thicknesses ?
