RE: Norvell carb air bleed
There is a fellow here in Canada that takes a carb from an AP (hornet I believe) and drills and taps for an adjustable airbleed. He stated the stock Norvel carb isnt "meaty" enough to drill and tap. He will not provide any further information, however. [

I have not tried to yet, but plan on it this winter. I just acquired my first Norvel and need to get some of the carbs now (its a CL version).
I am also going to try and fit other carbs I have to it.
Good luck and please share your experiences here with us. We all try and learn from one another - its the best way to help out IMO!

RE: Norvell carb air bleed
I just put a remote needle inline between the tank and the carb. I then opened the stock needle all the way and set the engine using the remote needle. After the top end was set I could set the bottom end using the stock needle on the carb. The nice thing is, beacause the norvel barrel moves as it rotates, you can have the stock needle not start to restrict fuel flow until it is nearly shut.

RE: Norvell carb air bleed
Thats A bit of good thinking Bipe, and to think i wnet to all the trouble i did!
I have installed an airbleed onto a new model carb, using that pesky throttle stop screw to adjust it. It was not to hard, though i think you want to do it by hand with a pin-vice (i used an old exacto knife handle.)
Though in my case i had to do mods to the carb to RICHEN the idle, as it was too lean. I also wanted to use it for my vampire ducted fan project, so i wanted to get rid of the mismatch/ step between the hole on the barrel and the carb body, while keeping the stock venturi size.
What i did is i used a tapered rheemer to enlarge the ends of the hole in the barrel (and the engine side of the carb body to match.) this richens the mixture. then i used the airbleed to adjust the mixture.

Got it! Neat idea. Man, some of you guys come up with some really cool ideas....
