It was acting up, so we pulled off the aircleaner, tied it down, and let it run for awhile. After a while, we got to watch a little "half-volcano" of ice crystals build up around the front side of the slide needle as the fuel was coming up around the needle. It never got big enough to close the throat, but it did get big enough to alter the proper airflow function of the carb. If I remember right, it was about 3/8" high, and 1/4" wide at the base. -------- Richard Pike Kolb MKIII N420P (420ldPoops) richard (at) bcchapel(dot)org Kingsport, TN 3TN0 Now faith is the substance of things hoped for, the evidence of things not seen.

There seems to be a general consensus that two strokes gas /oil mixtures ar e invincible to icing, if you have the BING 54 carbs on your two stroke 503 a s most Kolb Firestar pilots have they are not as prone to carb icing, because it works with a piston and not a valve as most other carbs do so most ice that will be formed will by design be sucked into the engine, and heated up to melt d own preventing the carb piston itself from freezing in a fixed position. The highest probability for carb icing is during a long decent. It's good General Aviation airmanship to add carb heat and clear the throttle at inte rvals during a glide approach, keep the power up, and remain with gliding distanc e of good fields until you get home and don't reduce power until you are sure yo u can make the field.
