never mind the post........above i figured it out. luckily my choke cabe broke in the process of tuning and about an hour later i took out the carb choke assy and put my thumb over the hole and to my surprise it idled awsome i quickly looked for something to plug the hole temporarily. took a bic pen and shoved it in the hole. my take is that the new cone performance filter i put on it was too much air flow for the spectrum of the choke. whaca guys think . could this be a problem other than cold starts?
