    Stihl 034 -> 036 upgrade

    Hello all, I bought a cheap china 036 (48mm) cilinder (without decrompression valve), piston and gasget and put it on my Stihl 034 from 2000. Today I got a chance to test it, and to my suprise I got it running. After heating it up slowly with a bit more oil added to the fuel I tuned the...

    Stihl 028AV clutch spring

    I suspect my clutch spring is worn of my Stihl 028AV (1985) because chain is running in low idle. So I ordered new clutch springs, but they are smaller than the springs in the saw. I ordered the 0000 997 5811 which i found in a old part list. What is the correct part number of a clutch spring...

    Stihl 046 cylinder

    Hello, I was offered a seized Stihl 046. I only have seen some pictures, as it is a 1.5 hour drive to pick it up. As it is seized, at least it needs a new cylinder kit. I found several brands of cylinders online. Does somebody has experience with one of the cylinder brands below? Meteor: USD...

    Stihl 028 AV wood boss rings/piston

    I think the compression is ok and it's more likely my very cheap compression set is wrong. I can't remember that I ever seen it over 125 ~ 130psi. (But I'm an amateur) And 4 pulls on cold start after carb was cleaned sounds good (warm only 1 pull). I do not have a vac tester. I ordered the...

    Stihl 028 AV wood boss rings/piston

    Today I changed the impulse hose and cleaned the carb again. The carburator is a Tillotson HU-40D, and I don’t have a rebuild kit for this one. But I have a walbro repair kit, and the diaphragm is nearly the same, so I thought let’s give it a try and replace the diaphragm. Reset the carb screws...

    Stihl 028 AV wood boss rings/piston

    Ok, assembled the saw and gave it a test run. After 4 pulls it started. It idles fine. But almost doesn't response to the throttle, the rpm's go up only a bit. Tried adjusting the carb, no change I'm going to replace the impulse hose and clean the carb again and see if that does the job

    Stihl 028 AV wood boss rings/piston

    Thanks pioneerguy! I received the new parts yesterday. Hopefully I can find some time today to assemble. I also ordered new cilinder gasket, fuel line and fuel filter. @wood doctor. Your saw looks almost new! Did you paint it white? Mine is also from 1985 or 1986. The original bar has 86...

    Stihl 028 AV wood boss rings/piston

    I bought an very old Stihl 028 Woodboss on a garage sale. I starts easily, didn’t tested it further. I started cleaning it and noticed a lot of carbon build up on the top of the piston. So I lifted the cylinder. I noticed there was also carbon underneath the piston rings. So I removed piston...

    Stihl 024 Service Manual

    I bought a vintage Stihl 024 1988 including HS-246 hedge trimmer attachment. Does somebody has the service manual or part list of the 024? I cannot find the part number of the sprocket, it’s lower than the newer versions of 024 / MS240 and doesn’t have a hole for the pin of the oiler worm gear.

    Replace bearings Stihl MS310?

    I allready replaced the bearings with new ones (SKF) to be on the safe side, they are not that expensive. The new bearings have also some play, but less then the old ones.

    Replace bearings Stihl MS310?

    I received the bearings and oil seals and rebuild the saw. Did a test run today, it cuts fine with lots of power. But can't get it to idle properly. Before discovering the air leak I replaced the fuel line, impulse line, carb kit and fuel filter and put in fresh fuel (Stihl moto mix) It’s a...

    Replace bearings Stihl MS310?

    Thanks for the feedback, I will also replace the bearings. I checked the rod (after watching some YouTube vids on what to look for). There is some sideway play, but no up/down play at all on the rod bearing. So the rod is fine I think. Cylinder and piston are in very good shape, so will keep...

    Replace bearings Stihl MS310?

    Started on a new project a MS310 of 2002. I got it running but after heating up it revved up on its own and died. So suspected an air leak. Started disassembling the saw, during the process I found the root cause. One bolt of the cylinder was loose. The complete thread was gone in cylinder...

    New cylinder bad compression

    Sanded the bottom of the cylinder. Squish is now 0.020” (0.5mm). Rebuild the saw yesterday and let de gasket dry for about a day. Tried the saw today, fired up quickly. Tried a small piece of oak, lots of power (for small saw at least)! Then the saw died, could not get it running...
