Have not run it enough to tell for sure but it seems to auto oil after I used the thumb pump. Almost like it needed primed or had some junk in the passage. It was hard to pump, got easy then started spitting oil. Seems like it throws oil on it's own now!

S is for sharpener, A is for auto oiler.
125psi is good. With the new top end, mine pulls around 130psi.

Finally putting my 4000 together. Starts and idles, but breaks up, like it shorting out, if use any throttle. Pulled flywheel and noticed the kill wire has some bare wire showing. Guess I need to replace it. Another issue is when I removed the coil , the coil wire pulled out. I can reinsert it but it’s a bit loose. Wonder if some sort of sealant or adhesive is advisable?
A dab of silicone to hold the coil wire in, wrap the kill wire with electrical tape, start up again and see if it is fixed

Tried the electrical tape step but got same results. Pulled flywheel and noticed the tape was worn. Guess it was too thick. Has to be the wire as I switched carbs with a good one and same issue. Woodruff key is in place so timing isn't off.

Finally put dads bought new poulan 3300 (maybe 93) and bought new TH mac (maybe 79-81) on the bench yesterday. Going to clean them up. Make sure running order and shelf them because they were dads.
The little poulan 2000 I gave him that I bought in 94 is already cleaned back up and being used pruning again this year. It had replaced that mac TH I despised using.

Bob take your grinder and remove the little part that has the hole in it like the picture. That is what messes with the wire. I removed it from all my flywheels. Has no effect on the way the saw runs

You mean the the section that is at the top of the triangular type piece at the bottom of ur picture? Not sure what u mean by “grind it”. Lower it or do away with the little hole?
Looks like Todd has done it on a lathe but could sneak in there with a grinder easy enough

Ok. I picked up some wire but it’s very stiff. Did order two from EBay but can always have extras.
Bob, that hole at the bottom of the picture grind it down flush, if you zoom in you can see how much, doesn't take much to clear the wire. The wire 14 GA is plenty
Grind it or remove it, just make it like the picture 
Not that would make a difference, I once asked the question if you had a flywheel with one broken fin should you remove the opposite and was told it wouldn't make a difference on the way it ran. That little bit of metal is a lot less than a fin.

Well, I’ve about run out of ideas. Made a new kill wire and saw starts and isles great. However it still breaksup at full throttle. I’ve replaced carb and still the same. Could it be the coil or flywheel?
Pull the coil off the 3800 and try again . Never had a flywheel go bad
I thought you had this same problem a while back,? With a 3400 or 3700, make sure you don’t have an air leak as well. Side to side saw stays at idle?
