Hi Shawn, Sorry to not reply. I was away for the holidays. This is getting long, and I'll bet not many people read it. Could someone out there explain in detail why a richer mixture is required when

Hey all this is a little long... Based on the CR topic discussion I have some other power related issues that I am dealing with. Regardless of my now uncertain CR, I have a GP3 cam with a Goodparts T

Have you tried going to thinner dashpot oil? It seems like it is possible that the slides are taking too long to respond to the increased vacuum as the RPMs climb. Usually the dyno readings are take

Along the lines of thinner oil - try no oil at all in the dashpots. The SCCA racers did this as a matter of course. I don't know why it works, but it's probably a function of the carb response at WO

Yup, it works. Can't really explain why either - just a MHO thing which probably isn't worth much. Been doing it since 1961 (TR3's) up to and including my 6. Word to the wise...the mixture must be ri

Shawn--I started to write a long reply to your post, regarding the fuel monitor picking up the bump in richness at 3,000. It got so unweildy I quit writing. There's too much for me to say for this ty

Thanks for all the input so far. I already have very thin oil in the dashpots. Please correct me if I'm wrong here. But as I see it is; as the needle is drawn up through the jet it tapers. If the mix

Hi Shawn, I think some of it is incorrect... The amount of fuel that enters from the needle/jet opening is a function of the difference in air pressure between inside the carb throat and the external

Shawn--Don Malling has posted a very good description of how CD carburetors work. Your original post suggested that you wanted to get a better needle for taking the richness "bump" out of the acceler

I've brought this up before, and I do so again only because it seems particularly relevant to this thread... In May, 1973 Motor Trend magazine ran an article about dyno-tuning a stock TR6. The articl

My thoughts about trying the thinner oil were more along the lines of the transient nature of your extremely rich condition where the ratio drops off the scale around 3000 (?) RPM. It appeared from

Actually the change needs to occur from about 2200 all the way to redline. Even after the power comes back up the mixture stays rich (right at 11 on the A/F from about 3300 to redline, it drops below

Hi Shawn and list, I don't think this is true for a Constant Depression carburetor. The air values rise and fall on the CD carbs so as to maintain a Constant Depression -- a constant vacuum. If there
