The carb was off a old IDC 28cc engine I can get the # off it if you want it. I used some information supplied by Ralph at RC Ignitions as follows:
Stripped carb including the welch plugs, then cleaned as normal rebuild.
I took a dremel with a straight bit and opened up the venturi area until I got tired of messing with it If my measurements are in the ball park it's at about 160% -170%Be carful you don't let the grinding bit touch the brass nipple you will see in the carb throat the other small drilled holes will be fixed up later so don't worry about them.
Now you need to open the fuel passages in the main body of the carb. You need to determine the size of the existing passages. I used a set of those tip cleaners welders use to clean their cutting torch tips.
PAY ATTENTION HERE, you want to determine the diameter of the existing passages and then double the area NOT THE DIAMETER so pi times the radius squared will give the area. I then just started measuring all my small bits until I found one that was close to being double the AREA NOT THE DIAMETER

I did not open the low needle but did the high needle, the one under the needle valve, the one under the smaller welch plug and the three under the larger welch plug these last ones open in the venturi that you ground up earlier.
This is all new to me but I then took a bit a few sizes larger and spun them backwards in the opening of the holes to clean up any burrs, seemed to work ok. Make sure you get the carb housing cleaned up from all the ginding.
I suggest you do all drilling by hand and not use a power drill.
As for rpm data I don’t have any yet. My test bench is a steel post in concrete outside and we have had nothing but wind and rain lately so for safety reasons I put on a flywheel and ran it in a vise in the lean-to off the side of my shop.
I picked up some meth and will be trying just meth with oil I was told this would work. We’ll see.

Fishmaster the burn rate on glow I am told is 2.16 times that of gas so try to get as much air in as you can I will try a little more next time. I am no expert but will try to help where I can if you need more info or I didn’t explain well enough just let me know.
I have to say again with very little needle adjustment the idle was great and the transition from low to high very good better than most of my glow engines.

This is not really as hard as it sounds so give it a try and I want to thank Ralph (RCignitions) for all the info it worked great.
