Chainsaw Repair

I’m back about the Husky Special 50.  I cannot get the saw to start.  I know I have spark because when I use starting fluid, it will turn over.  It runs til it burns the fluid then quits.  I have replaced fuel filter, fuel line, and did a partial rebuild on the carb, replacing the pump diaphragm, metering diaphragm and gaskets.  The screen was clean.  When I finished, the saw wouldn’t start, but I realized I might have the L and H out of adjustment.  When I turned them both out, the saw started and ran while the control was locked, but when I released the lock, the saw died.  I suspected it might be throttle related, but I don’t see that adjustment will change anything.  Now, it will start with starter fluid, but quits after the fluid is burned.  This still sounds fuel related, where do I go next?

Tune the low needle for best running with the throttle locked.

Before unlocking the throttle screw "in" the idle speed adjustment.

Unlock the throttle and try again for best running at idle.

Keep working at it until you get the saw speed down low enough that the chain doesn't spin.

Now you must get the engine where it will accelerate which will involve screwing out the low speed needle to where the engine will take the throttle.

Start with the needles at two turns . . .

We can talk about the high speed screw after you get the chainsaw to idle and accelerate?

That's the problem, the saw won't run long enough (when starter fluid burns, it stops dead) to adjust anything.

1) Don't use starting fluid in a two stroke engine
1a) Make sure that you have no kinks or sharp bends in the new fuel line
2) Get yourself a squirt bottle that you can use to squirt a little pre mix in the carb
3) Set the H&L jets at 1 turn out from lightly seated
4) Start pulling with the saw choked
5) When the saw fires return the choke to the run position but do not pull the trigger because the throttle is automatically set to fast idle by previous setting the choke to on
6) Pull again a couple of times, saw should start or at least fire a couple of times

Plus what 660 said above!

How can I post pictures?  When I try, it says they are too big.  Is there a special location?

stop using starter fluid. worst thing to use period.
get a small squirt bottle and put some properly mixed fuel in it.
