Carb adjusment
« on: January 17, 2013, 07:16:26 pm »
I was adjusting the carb on my 034s Yesterday and to get it to run perfect in the cut , My Hi screw is only about 3/4 turn out, is that acceptable? I don't want to run it to lean
The low is one turn out.

Are you using a tach to set your high speed? Does it 4 stroke at all out of the cut at full throttle.

I'm not using a tach. What RPMS should it be set at? can't remember if it 4 stroked out of the cut, don't think it did, but it would 4 stroke a little in the cut.

The orginial setting is 1 full turn out for the H needle and 1 full turn out for the L needle. The max rpms is 13,500. I would turn your H needle out just a touch more. If your 034 is screaming out of cut it might be too lean...a little conservative is better than too aggressive :)

Thanks, pressure tested the saw today and found the crank seal on the clutch side was leaking, probably why I was having trouble setting the carb. Destroyed two seals trying to put them in. What am I doing wrong?  I used a deep well socket that matched the size of the bearing, lined the seal up while keeping downward pressure and tried tapping in, just couldn’t get them to go in evenly one side or the other would always start going in first. Really frustrating destroying two OEM seals. Help Please

I Think i figured out why i can't get the seal in, I checked the inside diameter of the bearing, and its smaller than the diameter of the bearing i took out, not by much, I used a 7/8 deep well socket, and it fit tightly into the old bearing, but won't fit into the new bearing? WTF

Sure you got the right bearing, or seal. I have got some oe stuff and right part number but wrong part. I have had some seals that where real tight too. Try to get it started on one edge and work your way around, using your socket. It has worked for me as long as you have some movement around the crank. Just been patient with it. Lite taps with the hammer on the top of the socket.

I Think it was an after market Bearing (never again) I got so frustrated trying to get the seal in I totally tore the saw apart and ordered OEM bearings
the  after market bearing i used was just a hair smaller diameter than the new oem, i didn't measure the inside diameter, But like i said, I used a 7/8" deep well and it would fit tightly into the OEM bearing, But wouldn't fit into the aftermarket bearing. With the after market bearing being smaller inside diameter, it was like trying to put a square block in a round hole.

I agree. I always use oem bearings inside for the crank and piston pin bearings.
