Hi All, Been a lurker for sometime and everyone seems really helpful. I know i've learned a lot. Now, its my turn to ask the question as I'm at my wits end and frankly, I'd really like to figure this out rather than send it to a repair shop. I have a Husqvarna 350BT leaf blower. It was running fine last season and then towards the end of the season, it started to have a hard time staying on. When I give it gas, it would lose power and then eventually die, never to be started again. Fast forward to this season and it won't kick over. I have checked everyting but perhaps I'm doing something wrong. Has anyone expeirenced this before and if so, what can be done. Below is a list of things that I have done/checked. *New Spark Plug *New fuel filter *Semi clean air filter, not dirty enough to prevent starting (even tried it without the filter) *Cleaned carburetor and diaphragms. (there was rust where the needle/levers were, but I was able to clean all of that up fairly nicely with some TLC) didn't work after this even though I was confident it would. *Purchased a diaphragm/repair kit and replaced the lever, needle, spring, all diaphragms.. basically replace everything that was supposed to be replaced except for the needle seat. *Checked spark arrestor plate (clean) *Fuel line is clear and not blocked *Air Purge line is clear and not blocked *When primed, gas does goes through the carb, there's gas in the clear primer bubble *There's spark (unscrewed spark plug, connected it to wire, pulled cord and saw a very faint spark) so that rules out electrical. *Gas/Oil mixture is fine (although, possibly old gas as I don't remember when the last time it was that it was changed. *Coil pulls ok, it just won't kick over. **Hm... Could Old gas prevent this from starting? If so, is there anything I can add to the gas or do I need to get new gas? Do those gas additives really work?
