I have an os .46 fx w/ a rear mounted needle valve. I noticed as I test fitted the cowl on my Great Planes 182 ARF two things:

1. It looks as though the needle valve will remain under the cowling. in other words, its to short (?).

2. The front of standard muffler will hit the cowling, preventing the cowling from going on completely.


These two things lead to three questions I'm hoping someone here may be able to answer:

1. How will I adjust the needle valve with the cowl on? Even if I made a hole, the valve will not poke out high enough to reach.

2. What other types of mufflers will work with this type of plane and provide a better fit? I do like the relative quietness of this engine, not sure if a new different muffler will change things.

3. Can I use a remote glow igniter to prevent needing a hole for plug access?
