Be careful on the teflon tape. If one little piece gets loose, it will plug the port that the fuel goes through.......Not a good idea. I had one of the early DA50's, they were putting a bit of lock-tite or something on the needles........yep, after turning them a few times, the carb got plugged... I'm running the 3w80XI and have had no problems with fuel dripping out of my needles, but they are horizontal when the engine is mounted inverted. I had a Johnsered chainsaw years ago that had o-rings on the needles to prevent air from being sucked in. If fuel is dripping out of the needles, sounds like your diaphragm needle is sticking open, or has some trash under it. That's the first place I would look. You do have an odd problem here.


You shouldn't have to squirt fuel into the carb to get it started the first run of the day. Check and make sure your choke butterfly is closing all the way. All it takes is a hair open and they won't draw fuel near as well...
