Thread: Which is the Left ???

Hi All,

Ok ?.I've been having an issue with my RRC 2 Door Auto with CD175 Carbies.

They have always run rich and I developed a misfire lack of power which I have been working through.
After many months (rebuilding carbies) I have a vehicle that drives reasonably well, but still has a misfire and rich fuel smell and there is a noticeable sooty smoke from exhaust.

It also suffers that sometimes it refuses to accelerate properly (flat spot) that definitely can scare the bejesus from you when pulling out on traffic or taking off from lights.

I understand 3.5 v8's aren't the quickest motor vehicle (I've owned he for 10 years) and it's her style and basic functuality that has kept me being an enthusiast where others would have given up the ghost.
I thought I sorted the issue as I traced it to a conversion from an auto to manual choke from previous owner that while crude did the job.

Doing further investigation (Google is your friend) came across articles on the auto choke, and that it had a direct link to the fuel bowl when choke activated.
Reading article it said that if the piston that shut off this link (that makes the choke operable) is not working properly then the rich fuel smell was the cause.

I had a bright spark of an Idea and I pulled off the auto choke, and planked off where the choke goes and too it for a run to Byford last weekend.

Here's my question:

I've been told by people on this forum that 2,3,5 & 8 is fed by LH Carby and R H Carby feeds 1,4,6 & 7 sound silly but which carbie is the LH Side.

I have always taken the LH Side to be the passenger side which happened to have the choke on it.

Is that correct ?..The reason being after the run I have a vehicle that's hard to start when cold, (no choke) I still have a misfire, I still have a rich fuel smell and I removed spark plugs 2,3,5 & 8 which all had black soot around the electrode (which I believe is the reason for misfire)

I checked number 1 spark plug which as the nice clean grayish tone and I believe if I took the other plugs out (4,6 & 7) they would be in a similar condition to number 1

Is it a case I can't tell my left from my right and I should be looking at the other carbie as the source of the problem



Cheers

The first thing to do is check the diaphragms.
The second is to look into the carb throats and register where the main jet sits. It is sticking up around the needle. They should be equal and about AFAIR level with the bottom of the throat.

The third is to check the balance of the carbys.

And maybe the fourth is to check the float levels.
