Timber Bear not starting

This is a BADLY out of adjustment metering lever, much too high, that would cause your symptoms.

It's the aluminum looking tab correct?

Yes sir. But before you start bending it up or down, make sure you know the correct adjustment procedure for your model of carburetor.

Great lol. I have no idea what model it is. I'll have to look through my order records and see if I can find it

I have saw metering valves on new carbs so badly out of adjustment that the engine would "hydro lock" on gas.The aftermarket carbs are decent and inexpensive,but just keep in mind they are thrown together quickly to be sold at such a cheap price.When the end of the metering lever is pushed in,the needle valve should barely move up from its seat.That is always a good starting point.

So... I found out 2 years ago to the week I ordered a rebuild kit for the carb. Not a replacement.

So the diaphragms are probably still in good shape unless it's had ethonal fuel in it. If it has, that's likely the problem with the carb.

I've always tried to keep ethanol out, but there may have been a couple times it's had ethanol

That ethonal is not good for small engine carbs sitting over the winter. I learned the hard way.

I think the OP needs to take the carb apart to find the source of the problem. I am betting a stiff metering diaphragm, misadjusted metering lever, or both. Could also be a gummed-up inlet needle not sealing. I'd remove the carb and try a pressure test on the fuel line before I took apart.

How would I go about the pressure test?

I do it "ghetto style": blow on a piece of fuel line with my mouth and listen for a air leak inside the carb, haha.
"Proper" method is with a pressure tester, like a Mighty Vac

I'll give it a shot tomorrow. Thanks! Ordered a rebuild kit Incase it needs it

I think once you get the carb disassembled, the problem will present itself. I had a Walbro MDC that kept flooding a saw, I eventually discovered the service manual I was using had a mistake in a diagram, and I had it assembled wrong the whole time. Your saw should NOT be flooding that bad unless something is wrong inside the carb.

Who knows I could've put a gasket or diaphragm in wrong last rebuild...
I'm looking up a schematic for my carb so I know what's what.

I believe it's an HDB.

 

[forgetaboudit]

How's this looking?

 

[forgetaboudit]

I went through the carburetor everything is there that should be and seems to be in place. Nothing seemed overly hardened or unpliable.
With my son holding the throttle wide open and me pulling it, it pops once or twice every pull, but won't run. I've dialed the screws a 1/2 turn each direction and get no change. Started at low 1 turn, high 1-1/8 turn

Dang that sucks. I wish I knew what to tell you man. Maybe try 2 turns on the low? Maybe someone will have the answer for you.

As I recall that lever should be just flush with the level of the mounting surface, any higher they will flood
