Fine tuning a 162se

[Boomer2230]

I need a hand fine tuning my 162se, it had been sitting for a number of years and over the fall and winter I slowly was able to teach myself how to bring it back to life.
I was out trying it in some wood and noticed a bit of a popping sound when I was into the bigger wood. It also idles good but every once and a while it wants to die after making a cut. Any suggestions?

Here's a picture of the plug, it's not new, I have no idea how long it's been it it. Might be the original from 1978. Lol.

The plug looks like it’s tuned pretty rich. I shoot for somewhere between cardboard and chocolate color

Does that mean a little clockwise on the H screw?

If it’s 4 stroking (occasionally only firing every other rotation) in the cut, then yes

Look into rebuilding the carb with a carb kit. You might not get it to tune right if the diaphragms have gotten stiff. These carbs are very easy to rebuild. Youtube is your friend for carb rebuild and also tuning the saw. Important to get your ear tuned via watching a couple of tuning videos.

Fiddled around with it a bit more and it seems a bit better. Might have to get a new plug for it and set it after/better with a new plug.

Carb has been rebuilt, did this carb after I did the carb on my 61. I should hopefully have the final pieces to have both saws up and running. This one pukes out oil on the 20" bar and the 61 barely oils. I need some missing o-rings for the 61's oiler, but I also ordered an aftermarket one just in case. They want $150 for an OEM

Put another 2 tanks of fuel through it today, ran pretty well, but I think I'm still getting a popping sound under heavy load.

I'll put another couple through it tomorrow, should be a bit warmer out, and not so windy, but no mosquitoes

‘Popping’ (shooting ducks) is often an ignition problem and/or spark plug.

I agree with ignition.

4stroke sound when lifting:

Well I put a couple more tanks through the old girl, during which the end plate for the aftermarket muffler rattled off. No more popping. I don't know if the back pressure was the cause but without the little cover the old girl runs nicely. Going to have to fab up another cover for it and add a little mesh screen.

If you need the o-rings for the crank oil seal holder and oil pump, or the x-ring that goes to the output of the oil pump, give me a holler.

I need those for the 61.

@Boomer2230 ok I will send a pm here in a bit.

Ordered a deflector, 15 bucks, plus shipping. Even comes with SS mesh

Put another tank of fuel through the old girl yesterday, it really likes the open ended muffler, for a saw as old as I am, I'd put it up against a new saw.
