New Air Filter, Now it won't start 038av

[rktman]

After getting my 038 to spark again (thanks to a used ignition from Baileys), I decided to also replace my air filter since it had some of the floc missing and it was pretty clogged in other places.

After I installed the new air filter, getting it to start was a bear. So I adjusted the carb H & L settings to the basic 1 turn out setting. I also tried adjusting the idle to get it running smoother, but starting it is still tough. I still can't seem to get it just right.

Any suggestions on a proper adjusting sequence?

Thanks.

If it was starting good before you changed the filter, check that the choke is operating fully...

The choke does seem to be closing, although it doesn't hit unless the choke is off. Before it would start fine with the choke on, warm up, then turn choke off, and it ran normal. I'm thinking it's just way out of adjustment.

Update

Here is an update on my problem with saw.

When I installed the new (non-Stihl) air filter, I could not get the saw to run right no matter how the carb was adjusted. The funny thing was that it would run fine with the old air filter (with some carb adjustment).

My solution was to use the top half of the new filter and the bottom half of the old filter (which still had floc). After some more carb adjustment, it runs good and starts like normal. I think the aftermarket air filter was not allowing proper air flow or choke operation.
Bottom line, buy only Stihl filters.
Now if I can only get the darn thing to start oiling properly.

All the gray flocked 024, 028 ad 038 aftermarket filters are junk. When you tighten down the screws the body distorts and the choke won't operate fully. I have a box of perfectly good "looking" new filters that we won't use...

I just yesterday (Sun) replaced the filter on my newly acquired 30+ year old Power Mac 6 by using the old filter as a pattern and cutting out the new filter(s) from a green 'scritchy pad' material found in the sandpaper aisle at hardware stores. The stuff is make by Norton and is meant to replace '0' (fine) steel wool. I cut 6 new filters from 2 - 4.5" x 5.5" pads for $2. Stick a 16d nail thru the new filters to make the mounting hole. The pads are sold as 'synthetic steel wool'.

:yoyo: So sap, You say you made air filters out of abrasive material?:yoyo:


Do you know how hard it is to type while laughing??

Let us know how it works out, well keep an eye on the trading post- "looking for piston and cylinder for Power Mac 6."

Sounds like a disaster waiting to happen.
Abrasive & intake never ends well.

abrassive

I hear the green stuff will port, snd the gray stuff will polish.:hmm3grin2orange:

Another great move by sap... gheez...

Hey Sap,

What was that phrase? Oh yeah...

"F'ing Priceless"

.

Newsflash to all you lowbrow wannabe rocket scientists: Simply because something can be used as an 'abrasive' doesn't mean that it can't be used as a filtering medium also. I don't plan on rubbing the carb with it...although I guess it would do double duty to scrub off those pesky deposits. Hahahahaha!
The synthetic steel wool is in mat form and doesn't shed particles like steel wool. Pond filter medium can also be used as an abrasive if you scrub something with it...but it's still a filter medium.
What do you think the difference is between the course filter medium found in factory 'filters' and the stuff I pointed out? Uh, that would be nothing....it's the same stuff, a plastic/polymer matting.

'Jeez' is right.

 

[LarryTheCableGuy]

Oh my. Well, at least Sap didn't cut it or poke holes in it...allowing pieces to vibrate loose.

Wait a minute...

It's a woven matting. Poking a hole thru it only makes the threads of the weave spread. There are no 'pieces'.

So your into the filters for $2 , the saw was probably a tire chalk to Begin with, but wouldn't you agree that anything worth doing is worth doing right?

I don't care what you say sap, I just hope that novice members understand that your an absolute wing-nut when it comes to ideas, IOW, your useless.

If vibrations of the saw cause the brillo-pad to lose just one speck of fiber, stuck in a ring grove , no ifs, ands or buts, it will wipe out the jug!

...and you CUT six of them from one pad. Still going to insist that there are no pieces?

[coveredinsap]

How do you think the matting on factory filters gets into that exact shape ...devine intervention? It's cut, that's how. There is as much chance of particulate matter shedding from a factory filter as there is from a homemade one, especially if you wash it off prior to installing it.
You do wash off your factory filters prior to using them to make sure they are free of manufacturing debris, right?

My mistake, as I forgot the most important rule of all:

You can always tell a Sap but you can NEVER tell him much.

So true!

What I think the funnest part is that he is biasing his whole hypothesis on the fact that if it looks like a filter material, so it is filter material. The part that it was structured as an abrasive just slips his frame of thought.

Wonder if sap had put 2 and 2 together yet, the flock that comes out of regular filters has to go somewhere, a lot must go through the engine, but not a liberal source of engine wear?
