It should be written in the documents you got with the carb

I have a 38mm Smart Carb. These were my factory settings:
Metering Rod: Q11 Factory Tuned Clicker Count: 63 Clicks (Click count from full rich - Turn Right) Slide Length 3.901 Idle Set-Screw Setting: .735" |

I've only spent a bit of time fiddling with my SC, and it seems like it's somewhat close to where I want it. I spent some time last nite reading the tuning guide at the link gasgasman provided.
The more I learn about this carb, the more I come to think it is a pretty clever design. I've had to change my thinking about carburetors and how they work- at least this one anyways. Much of the process is initially counter-intuitive & you have to scrap the typical tuning process you'd use on other carbs. At this point, I'm sold. Love the idea of set it and forget it. I'm going to do some final tuning this wknd. |

Thank you for that guys, I will dive into it on Sunday afternoon.

I have been sneaking up on my settings too. I haven't had as much riding time as I would like. But I will get there too.

Unusual setting
Hello Guys,
I own a 2008 EC300, Stock Motor, Gnarly Pipe and FMF Turbinecore2. New Spark plug 1 size hotter BR7EG. With the Smartcarb (38mm Billet) the idle is a problem. With standard Setting(as delivered and documented in manual) Valve height2mm and needle+Slide/Rod length 99,1mm (3,901") I have a return from open Throttle with normal (desired) idle rpm, but after 1 or 2 secounds it drops and soon Motor stalls. I tried to lean the rod, but the high idle always sooner or later drops to stall. I now had the following strategy: Make the Carb richer so rpm drops fast after open throttle and enhance idle (gap). This leaves me at standard Slide/rod length 99,1mm but a stable return to idle. Only issue is, that idle gap is 3,7mm. Far away from the recommended 2mm(+-0,5mm). Has anyone made similar experience? By the way, my manual says the carb has a 35HiFlo Needle+seat. What does that mean? Important for me is a very good consistent and predictable smooth power delivery from bottom, as I do X-Training with a lot slow tricky stuff. Ideally engine would behave like my 250TXT GasGAs trials bike. In the EC300 my Keihin delivers here after endless mods(see below, except for stalling on steep descent). Best regards, Erhard P.S.: I am convinced i have no issues with air leaks, broken Membranes or such. The Motor runs good, switching back to Keihin PWK 38(slide9, N1EG clip2, Main 168, Idle 40, Idle screw 1,5T out, warmer spark Plug-important!). Only backdraw of Keihin is a delayed transition onto Pipe (Powervalve opening). In tricky Terrain it appears Keihin delivers softer Power(better than SC). Keihin tends to stall at steep descends. I had endless tuning on the Keihin, starting with JD kit. Now I tried a #9Slide and feel to have the best combination now. #7 never was totally convincing. With N1ef/slide#7 it was always loading up in slow sections...endless as sayed. SC was better from out of the box, if only it idled... Last edited by Erhard; 08-16-2016 at 10:30 AM. |

If you're a member of the KTMtalk forum you might post the question over there. They have a sticky in the jetting section for setting up the SmartCarb that is fairly active and frequently updated. I couldn't ever get my SmartCarb to idle consistently but I can't rule out an air leak (maybe crank seals). I reinstalled the PWK but can't get a consistent idle with it either. If I ever get around to replacing the crank seals I'll try the SmartCarb again. Sorry, I'm not more help.

A simple turn of the idle screw may help a bit.
I would not try to use the mixture screw to set the idle speed. Fuel quality plays a major factor too. I try to run 50/50 race gas and pump swill. |
