Stihl shop made an honest mistake or was going to try to charge me twice for the 2 rings and piston pin. However, I would not have to buy the following as stated by that other stihl shop:īecause these items are included with Piston 413 $63.55. To this list previous mentioned in my last post: If I purchased individually, the stihl guy told me that I would need to add the following: To change out my old carb, S28D, which is around $60-$70 because it would not work with a short block. I checked with my local stihl and was told that the short block $175 but I would also have That is a great idea to do a short block and it would cut the labor costs as well.

The 4137 series engine was a good one, we were still selling the FS-80 up until just last week when it became NLA. Robert, no offense, but if you don't even know what a venturi is, you really shouldn't be working on your carb. They are a product of the clean air laws, as they will not let you richen the carb too much. Needle limiter caps are a pita and we are always removing them so an adjustment can be made. No comebacks and a better performing piece of equipment. A new carb is almost always a better fix. If it still will not pull fuel, a new carb is put on. Once we determine the spark and compression are good, I will attemp to clean a carb one time. We call them a BS carb, that should give you a clue about them. It sounds like you have what Stihl calls a BIS carb, or Balanced Idle System. Most often the replacement makes the machine run well again, as it no longer has an outside source of air. It's pretty rare to see an intake manifold cracked, but it does happen. Welch plugs are small, aluminum domed discs that are pressed into place over the low speed acceleration ports for access to these ports at a later date by the mechanic.
Stihl string trimmer how to#
I also heard other folks saying you just have to learn how to 'adjust' it. With the high end screw somewhere past the manufactured stopping point.ĭoesn't run 100% perfect but it's close enough for me.Īs I said I can't tell you to do that, but when I asked about this at the dealership they said the procedure isn't unheard of. Once that was done it was easy to adjust it, and I got it running pretty good Plastic sleeve broke and allowed the adjustment screw to go past the stop. Then I turned it up to where the plastic hits that stop and kept going until that POS Needle nose vise grip and clamped it on to the HIGH adjustment screw, the plastic part. That wasn't the only thing I had replaced but long story short I was a bit pissed, so one day I took a Now I can't recommend you do it, but just like yourself I replaced the carburetor and hence had a spare. I had a similar problem and I got so tired of it doing that, I accidentally figured something out. When I start it up and let up on the trigger it wants to die off on me and also if I try to use it with the trigger fully pressed it gets sluggish when I cut weeds with it. That did not seem to fix the problem I am having with it. I put on a carbeurator kit, cleaned the orfices with starter fluid, cleaned the fuel tank, put on new fuel line with fuel filter and return lines. That way he knew the coil was working and that the spark plug was working, too. Well, he put the spark plug and attached it to the spark plug wire and put it up against metal on the side of the weedeater and pulled the starter pulley to make sure that it was creating a spark. I took the stihl fs80 over to my brother in law and he put the wire back through the boot and I guess clipped it into that wire spring inside the boot. I tried to take the spark plug wire off the spark plug but it was stuck on to the spark plug but when I pulled on it the other end of the spark plug boot ripped the wire out of it.
Here is what I have done to try to fix it as follows: The carbeurator is a stihl S28D that has an adjustable screw for air intake into the carbeutor and thought that it might be the problem with it but then again I thought maybe its the low idle screw that needs adjusted I simply do not know and just guessing. The EPA sticker on the shaft has 1998 written in it so that is why I believe it was made around 1998 period. I have a stihl fs80 string trimmer that I bought used off ebay recently.
