Good morning everyone, Finished my first Carb rebuild yesterday and it felt great. Well for about 15 minutes then saw died again. I checked the gas since i didnt put much in and when i took cap off there was a hiss which got me thinking about the vent. Put cap back on and it fired right back up . Pulled vent hose and it was plugged up. I went and ordered new hose and asked them if they could check RPM after i rebuilt the carb and they adjusted it and check RPM for free!! Now that is great service compared to what i was used to at old place. They just wanted to sell me a new saw. I normally would not have touched the carb but with all the great information on here i gave it a try. Besides if i ran into any trouble i had all of the experts on here to ask. Thanks again everyone.
