This 5000 was ran dry at idle in the spring and never used again and stored on the shelf. Today i fueled it up and it wouldnt pull fuel through the line. So I primed it and still didnt pull fuel. So i check the line and it felt stiff and had hardened over the last 2 years. So i pulled the line and put new fuel line in it.
Primed a couple times more and still didnt pull fuel to the carb. Runs great on prime till fuel is run out of carb, just like it used to.

I got cold in the 20 degree so I gave up for today.

I'm thinking diaphragm has got stiff or the check valve flap on the other side dia is stuck or maybe the impulse seal to carb.

What do you think?

What carb is on it?

The small oem carb off a 490 without the brass gov. I would have to look for actual numbers on carb.

I think this saw had come from your way at one time. I noticed the 2 holes like the redmax 5000 in rear handle flat area.

Unless Simon Bertrand sold me a 5000 like that too. I'm losing track.

The one that I sent you had the starter side grenade in the cut. Is this that one?

That one that blew the recoil in the cut was stock. But it could be that one still, just woods ported now

.

I will have to check.

Couple of the runners at the time. I think I had 3x that on the shelf when I started selling off.

Wouldn't run on prime if the needle is stuck, if you don't mean priming by giving a shot on the air filter. Think the pump membrane has gone bad or you got the impulse channel clogged or leaking. Membranes often go simultaneously with the fuel lines.

This is the same saw Al Smith ran at Chardon and NWPA GTG with small oem carb and lesser chain. It was right on the heels of my good 5000 at the gtg, bad start at chardon.

By me saying prime. I was using my squirt bottle to spray mix straight through the carb through the intake and into cylinder. It would run till mix was used up. So bypassing carb really.

That pot licker is a runner,I'll testify to that fact .It just would not suck fuel yesterday .

My suspisions are stiff check valves .Now I've ran them dry,left fuel in them found really no difference .That damned ethanol just stiffens the innards up .

The last few carb kits I got it looked like the checks were made of a material more robust to the effects of ethanol .The earlier versions used what appeared to be buna N which is not as robust .BTW ,Stihl crankshaft seals are a tad different also than earlier versions .

I wish they would use that corn to fatten cattle and make whiskey instead of sticking the stuff in the gasoline tank .Might as well chit in one hand and wish in the other .Good grief !

Just as a side note on that carb let me add something .My 2100 Homelite has a large fuel line and a large carb .If it sits for a long time ,which it does I have to prime it .Either that or rollover 114 cc of saw engine until my arm about drops off .

It takes about 2 prime cycles to suck that line full of gas but like I said it's large .Now once full that line will hold gas for about three weeks to a month because the checks are working or at least were the last I used it .

That tid bit aside checks or no it's most likely re kit time .Chit happens !

I just had a thought occur to me that might be something or just a waste of time .

I've taken apart those old boat anchors that were ran on heavy oil mix,16 to 1 .They smoked like they were burning soft coal back then .However even after decades of sitting and the motor oil evaporated and left an oily residue those things had carb innards that were as supple as they likely were when they were new .

I just wonder if a person ran the things dry then fired it back up with oily gas then drained the tank if the long term storage would be any better .

TIP: On the partner 500 and 5000 there is a little hole through flywheel and crankcase. Align both holes up and slide a align wrench or other steel object same size as hole into crankcase.
Then you can remove clutch, flywheel nut etc without using rope or stop through spark-plug hole.
