REEDY TUNE PROBLEMS

The Reedy carb has a fairly small tuning window. Be sure to adjust in very small increments especially on the HSN.

what needle settings are you guys at roughly?

1.) Set idle gap to roughly .7-.8mm (get motor up to full temp before tuning)
2.) HSN is very sensitive, 1hr makes very noticeable difference, LSN not as touchy.
3.) Once HSN comfy, set LSN to where it won't lean bog, and come from cleaned out down to idle very promptly, this is how you know LSN is correct.
4.) What do you mean when you say "extra" shim?? If you are running what came in the motor PLUS th extra 3rd one in the box, AND, 20% fuel, it will never run right. All the shims together equal .95mm, and you can use the stock .55 with 30%. Shim it to stock and it should immediatly help especially with lower nitro.
4.) Stock setting with a sensitive HSN are hard to give, humidity and ambient temp make a big difference in needle settings, as well as plug choice. I have had great luck with OD 97T, and some like a P4. P3 is too hot of a plug for most areas in summer time.

We also tried a OS 2050, and it ran very well. Here is another observation also, depending on what brand clutch, you may want to try running heavier clutch springs, this is just what we noticed..
Good Luck

I need help. My motor temps between 240-285 and runs great but it continues to stalls when I let off the throttle and begin to turn. I adjusted the idle screw without success. The motor seems better when the LSN and the HSN are set real lean. Any suggestions?
SPEEDSKI what kind of fuel mileage are you getting with the OS 2050??

Also guy with the Exergen temp gun, are you getting a high reading on the head than the crank case? I noticed with my OS motors they were very close to each other. With the Reedy I can get the thing perfectly tune, just an hour from being rich and the head temps 295-300 but the case is at 250. If I back down the settings its way to fat.

Send me PM, we can discuss critical factors, I really hate giving "settings" because I have learned over the past few months as temps and humidity has changed big time, it makes a difference.
As for a basic setting, I have found once I set the idle gap, if I bottom out the LSN then back it off 2 and 3/4 turns, it's pretty close, then also bottom out the HSN and back it off about 2 1/4 turn it's pretty close.
Keep in mind that the HSN is sensitive, an hour makes a great difference. So the 2 1/4 turns may not be perfect. Also the type of fuel will change tune. I run Sidewinder 30% witrh these settings, and 97T.
