Probably worth asking on either the RSOC forum or Passionford tbh as you should get a pretty quick answer there tbh

Set ign timing to 12 degrees btdc fueling 1.5- 2.0% @ idle (rich but safer) then go from there as with any modded engine can take some messing around to get it right.
If it has a dump valve fitted take it off as these engines do not like them and no matter what type it is it will cause you problems.

From memory when I had my S1 RST the idle screw as you call it is not used to control the idle, it is used to help set up the throttle position switch, the idle speed is adjusted by a fairly big knurled headed screw under the throttle body and when doing so I think you have to disconnect the plug from the fuel pressure unit on the side of the metering unit.Good luck

ps Hope you guys dont mind me highjacking your forum

You sure? Mine seems to run great with the dump valve fitted. I thought this problem was rectified by Bailey years ago?

I have probably just jinxed myself with the above statment

Hi

To be honest unless you are confident in what you are trying to do i would take it somewhere and have it set up on the rolling Road. You can do alot of damage if it is set up wrong either way.

yes the idle scew i ment was the big one under the throttle body, didntbrelise the you had to disconect the conector on the fuel metering unit, thanks for the help

The twin piston dump valves do solve the problem of stalling, but dont solve the problem of it losing all the air in the induction system that the ecu thinks is there, and therfore fuels for. When you back off you get a load of fuel but no air in the engine causing overfuelling.
Dump valve really are not needed at reasonable boost levels on the rst engine and are normally fitted for the noise.
