I think my 046 runs a Tillotson, not sure which one, I would have to look.
I never have seen that carb series that I can recall but not sure why it would be better or worse than the others for it unless Venturi size is bigger or something. Most 044/046 run a tillitson hs series I believe or the walbro hd or a zama. But I may be wrong because I think all my 044/046 saws I’ve had or worked on were zama or walbro.
The reason why I’m interested is because it’s half the price of a new Walbro or Zama.
Tea has more caffeine than coffee, so I heard.
Dealership should have the carb tuning tool, but if it ran fine a couple of years ago carb tuning most likely isn't the problem. I'd start upstream with fuel filter and tank vent/valve. Pull the filter and vent off and run it.
Where is the vent located, the filter looks like new, the old fuel was not even bad, it was still mixed and not all separated
The carb needs cleaning and rebuild, they do have a special tool for adjusting the jets. I usually pull the limiters on them, to get them out you need to drill the little pins out of carb housing so the limiters can be pulled out past pin end. I would need to look in the book to see what tool is used to adjust with limiters in.
I think so, two and a half years laying with fuel in the carb will have messed with the diaphram and the passages could be clogged too.
I'd pull the filter off anyway. Just takes a second. If you can't find a tank vent then crack the fuel cap open a bit. Move on to the carb if nothing improves. With a rebuilt carb it won't run well with a dirty filter or clogged vent, but it does need rebuilding or replacing after sitting so long regardless. It should run with different fuel, maybe not as well.
The carb is more than likely plugged especially if it was ethanol gas, I’ve gotten quite a few next to new saws that people bought for a storm tree. The saw cuts one tree or something gos on shelf for 2-3 years and another storm hits. Saw won’t start gos to shop and they quote 100$ plus parts to rebuild carb and tune. Guy says only payed 170 for saw buys another instead, usually same thing happens to that one because they didn’t learn to drain it and run till quits. Then put a tank of canned fuel in start and store with that. Most should just use canned gas all the time for limited use. Good call on not running anymore till carb is cleaned, the bog is a lean condition and could damage saw if you keep trying without a carb cleaning.
I will do, best to rule out the simple things first. This saw always had to be feathered even when using standard mixed fuel,
If you think you'll be using it regularly, may be worthwhile to replace fuel filter, fuel line, vent, carb, impulse line, maybe manifold but probably not.
Thanks, I did spot those pins in a video, are they top and bottom thus both need drilled, or is there just the one pin perhas on the top only that needs to be drilled.
I will get it cleaned and a oem kit in it, does anyone know wherre the meterig level should be, does it finish flush with the carb body.
If it's a WT it should be below the body, even with the top of the depression it sits in.
