I have a ryobi 3818. This saws been a workhorse for me until just recently it wouldn’t start. I came to the conclusion it was a cracked fuel line. I replaced the fuel lines. Still won’t run. I took apart the carb and cleaned it. It will run on choke for a few seconds but when I pull the throttle it dies. I replaced the carb, and the gaskets and I still get the same result. Also with the new carb, the choke doesn’t want to pull all the way out. Don’t know if that’s related or if I installed it incorrectly.
Any suggestions that I should try next? I’ve done all that I can think to do.
My guess is carb issue of some sort as they’re the bane of my existence.

I just had my house repiped due to 40 years of sulphur build up in the copper pipes. It was highly recommended that I get an aom sulphur filter to eliminate the sulphur gas in the lines. I’m a handy guy and don’t want to pay someone to install it so I’m looking for recommendations as to what filter I should get.

I also have a water softener which eliminates most of the iron in the water (about 1ppm after the softener). I’m guessing I should put the sulphur filter before the water softener or am I wrong in assuming that?
Or am I better getting a sulphur/iron combo filter. I read that strict sulphur filters require little to no maintenance where as the iron/sulphur combo requires media changes more frequently. The 1 ppm of iron doesn’t bother me seems I can’t taste it and it’s not staining the house or clothes. So that’s why I’m leaning towards the strict sulphur filter.

Any truth to that?
Thanks in advance for any advice you might have!
