No LSN?
I have only previously worked with a .18 engine slide carb that had Idle, LSN and HSN - that I can deal with.
But I have one now (.18 again) with a rotary carb and only 2 adjustments. One is defo HSN, and the other is the idle speed screw (from reading online), although it doesn't seem to change anything.
I can't find much online regarding this and im having trouble getting the brake to engage without closing off the carb and stalling the engine (which might just be a mechanical issue of course).
Same as this http://www.r2hobbies.com/images/VH-201/03.jpg (although the carb on there is reversed). Or am I missing someway to adjust the LSN?

RE: No LSN?
My trouble before was getting the idle screw to work, I got it sorted now by holding the carb open and screwing the idle all the way in (before setting it correctly), now works as intended and idles perfect.
I wasn't sure what to call the carb with a single needle (seems obvious now) so I was able to look it up, and can see the pitfalls (and "benefits") , I have a spare engine with a 2 needle carb so will probably swap it over sometime.

Most SNV carbs work "good" but a 2 or 3 needle work "better".
Good to hear you got it set right.
