For your car, I would bolt it on first and see how it runs. Your motor will let you know if it needs more jet or not. If it starts to lay down on the first pass, get out of the throttle. Alchy burns stuff up in a hurry if it's too lean. I made one pass with mine too lean and it burned the electrodes off half the plugs.
I also run one step colder plug than on gas, and maybe add some initial timing (the last one once again is dependant upon the motor). Plus it helps to have a small bottle of gas to start it the first time for the day. Squirt a little gas down the carb before trying to fire it the first time each day, and it should pop right off. Also, alchy likes heat. Try and keep more heat in the motor than you would normally on gas. I try to stage at 170* with mine. Plus, the last pass of the day, get the temp up over 185* befor shutting it off (I like mine between 190-200), and leave it there, don't run the fans and pump to cool it off. It helps evaporate the moisture out of the crankcase and will keep the oil cleaner.
