Hi Folks

I have a friend who is very keen to have one of his 048's ported.
Limitations I see are short stroke to bore, big thick rings, thick heavy clutch and crap air filter.

He is interested in me fitting a V Stack and pod filter to get around the air filter availability issue and the rest should be ok.

Anyone got any experience or advice on the Stihl 048?

I'd say give it an 046 recipe and bump the timing at least .025
A fine mesh screen air filter should breathe good enough.

Always had problems with my 048 ignition system no mater where or what module was used. Converted the saw to a 029/290 112? type 1300 series coil. It never ran so good. Almost cooked it once. It blew a puff of muffler smoke and shut down. Toasted the rings a little. It needs a lightened piston and shorter blow-down. They run well when given some good blue flame. Build the saw and then convert the coil after testing. Night and day IMO. It's an old design but one of the better factory builds. Tough too. Built for the fire services. 048S would be more fun :uptosomething:

I have no idea what they will do souped .I have two 048's and one 042 all stock .The wire mesh filters come up on flea bay from time to time .I've never seen a flocked filter sell .Clutch side seal is almost impossible to find and it's OEM .I have one left and one of mine needs a seal .I think the rings are the same as an 038 Mag .One of mine could stand a new set .

042 pistons and cylinders are rare as a hens tooth.Even stock they cut okay nothing wrong with them .If I recall correctly at the time the 048 had the highest power to weight ratio of any saw built during that time period .

Having said that I don't think either one is highly sought after or rare .Some people think they are worth a fortune ,I don't .

Looks like it is a super.

What is the displacement on an 048 super ?
I have run an 048 quite a few hours and put a few on some 042's. I always was very happy with the performance of either. I did like running the 048 better then an 056 super. I think the 048 filter was easier to maintain also. Actually I think I have 2 042 projects stored and and an o48 top end to put on 1.

I went looking for the difference between 048 and 048 super and still not sure of the difference.

Perhaps a different carb and changed port timings like 076 and 076 super?

The difference on the 048 super is supposed to be a dual port muffler vs single outlet. Same displacement for sure.

I have an 042 I have had for 38 years and have never done any! I repeat anything to it. Pulled it out from under bench last week after 1.5 years since last start and pull a dozen or so times and fired up.Went outside and cut half a tree up with it without a hitch.Have an 024 in same category. Kinda debunks the "carb rebuild replace all lines,spark plug theory" to me. Also had a jonsered 670 that never had nothing in 20 years of ownership.

There might be a diff in the super,which BTW I've never seen If I am correct the regular 048 has a baffled muffler and possibly the super has a pressure can .I got the big orange dealers IPL book ,I'll look in a sec .

I took a peek and they actually list 4 mufflers .Two look like one piece and one must be special because they list it as fire safe .The others are two piece .

The coil is not limited .As a matter of fact it's a self advancing coil according to the book if it's OEM .Which makes trying to advance same really a waste of time .On the other hand weather it will advance any more than 28 degrees or not I haven't a clue .Maybe somebody knows for sure .
