i recently installed a pullstart on my engine and before i installed the pull start i hadnt ran my car for almost a week and the last time i ran it was un-tuned. so i went to retune my engine and for some reason right now it doesnt idle right but once i get it running at a speed it runs unbeleivable, the second i go to idle it, it dies out. i cant seem to find a medium to where both work out well. i guess one of my main questions is, how can i get it to idle(which screw needs to be messed with, idle set or lowspeed) ? im unable to start it unless i hold the throttle down.
