I posted before about my rough idle problem. It has new rings and the carbs rebuilt. I took it back to the dealer i bought it from and complained, he said he would fix it for free! I picked it up today, didn`t get to talk to mechanic, but the counter person said it was ready to go. So i don`t know what they replaced. I took the cover off, looks like they replaced all four coils. I put it in the water today, it runs alot better and it was idling a little fast, so i backed it off. I noticed they had the idle adjust screw almost all the way in. Why would it have to be almost maxed out?
