The top up position gives a carb a 150% enrichment, about 9:1 air fuel ratio, while turning it back makes it a normal functioing carb at some point. So you can remove the choke, and use the first third of movement as cold sart enrichment, and a working portion as a closed loop stoich control, and then t rest an open loop performance mixture. Each portion can be cruise controlled within an EGT or single O2 sensor stricture. The maker used old Marvel Schelber tricks in his Ellisons injection, and the Holley 2300 series has the worst roosters tail around, and adding the Tom McNeilly kit kills two bad birds (turbo charge density air fuel control and bad mixture distirbution and too large atomisation fuel ball micron sizes over 70 microns) with one simple 150 US dollar stone.
Love what your doing.
xctasy":18mj77f5 said:All you need is some Area 51 Technology!. You have no choice but to use the stuff you have, your under carb adaptor you have, the carb you have, and take the carb to a machinist and have him shave off all of your existing carb's choke air horn and carb mounting flange so it ends up like the ones on the outer Chrysler 340 and 440 six pack Holley carb below.
Then use an adjustable main jet to operate cold start enrichment.
There are two types, but I'd recomend the one the Mazda Rotory guys use, sourced from Tom McNeilly tomcn@earthlink.net for US $150 dollars excluding post and packaging.These are throttle leaning devices used for light aircraft
