After sitting for a few years my gen wouldn't start. Had carb cleaned and rebuilt. Gen will start and run great at idle but as soon as load is turned on it starts to hunt a little then runs at a reduced rpm and will backfire after a few minutes then shut down. It will then restart after a few attempts but will not take load. After a couple days, will start perfect and run great for a long time until load is added.
Ideas????
