I believe the A/F Ratio Adjust

I believe the A/F Ratio Adjustment "Plug" is missing on my car. This is the plug which covers the mixture screw. Does someone have a picture of what it looks like? What is it made out of? Is there something else I can use to replace it?
Possibly from an old VW CIS?

Thanks in advance!!

Hi Mr. Manzonelli,

The plu


Hi Mr. Manzonelli,

The plug is a small round tapered aluminum piece. Available from McCann (amongst others) for about $8. Don't have part # here at work. If you're going to be adjusting, the older VWs (early 80s?) apparently have a small rubber plug with built-in wire handle for easier removal.

My TR was missing the two plug

My TR was missing the two plugs, so I'm simply gonna use the appropriate bolt (not too long) with a thick o-ring. Does anyone think this will cause problems?

Thanks everyone.

I will loo


Thanks everyone.

I will look again. I definately do not have the plug that Carl shows. I have to check and see if mine is similar to what Henry has. I will try and do that later today and let you know what I find.

My plug was definately missing

My plug was definately missing. I sprayed some carb cleaner around the hole and the rpms made a change. I fabricated a rubber plug which holds well. I tested it by spraying carb cleaner at it again. No change in RPM. Looks good.

I swear the car feels like a new machine. it idles smoother and seems much more linear all the way through. I am going for another drive because it feels so good.

Thanks again for everyone's insight!!!

Bill,

Mine is not threaded.


Bill,

Mine is not threaded. It is built for a plug which looks exactly as what Carl's picture shows. The way the plug OPENING is designed, it makes for the ability to install the plug w/o having it fall through. (Like metal tabs which keep it from falling through). You could probably thread a screw in there but I don't think you will get a good seal. Take a look and you will see what I am saying (that is if you currently do not have a plug there)
