I have a 359 that will not run consistantly. when I start it runs wide open fine(every time) but some times it idles for about 15 to 20 seconds then revs up then dies. After it dies one pull and it idles but if you try to open it up it bogs and stalls. My local dealer said he checked all the seals and gaskets with carb cleaner and there are no air leaks. Some times it runs like a new saw. Idles perfect revs up. I purchased a carb kit on ebay hopefuly this helps. Any help is appreciated.:bang:
