024 info
« on: June 15, 2012, 10:03:04 pm »
I picked up an 024 on the cheap today .It runs they say,piston is little rough ,has good compression etc .I've saved worse looking .

Now the big question which I don't know is will an 026 cylinder bolt on the this little pup ? I've never worked on one so I have no idea .

I'm going to have to investigate the little thing I guess .I have no idea what the stroke is on that thing .

Norwood shows an aftemarket bolt on for an 026 with an odd ball 44.7 mm bore which should bring it up to about 50 cc more or less .

On the other hand it might be such a deal as taking an 038 av up to 38 Mag specs with all that carving and twittering to get the cylinder to fit .Might just as well start out with another saw than try to make a silk purse from a sow's ear .

I'll get the little pup running good ,that's not going to be a problem at all .How well remains to be seen . ;D

Your max kW (hp) rpm specs are way off, otherwise you are right.  ;D

That is from an old Stihl workshop manual. I never put much faith in those HP or KW figures anyway. Those were supposedly measured at 7000 rpm? I always figure that the numbers are just something they pulled out of the air?

Well according to the specs as per Stihl micro fitche they give max torque at 7,000 on that series of saws .I'm thinking like the 024 they set max RPMs at 12 thou and on the 026 13 thou maybe .Of course that doesn't mean much if you doctor with the porting .

Itty bitty little engine like that it wouldn't take much to crank it  on a 15 if you wanted it to .

Might sound hard to believe but a few years back according to some a pair of 024's showed up a GTG and ran an astouding 22 thou and held together .They didn't say for how long though.  ;)

Well good grief now I feel about half stupid .All this deal with this little saw was simpley to get a 3 cuber I could play with at the GTG's and all along I have an 028 in the shed .All this time I thought it was over the 3 cube limit .Then I did some research and find it's 47 cc's . :D
