    Chainsaw hard to start (2)

    I have two Sthil MS251 chainsaws and both are almost impossible to start. I have changed the spark plug, installed a new Air Filter, I use fresh gas (ethanol free). I use the 3-4 short pulls to prime and then the big pull to start, but they do not start. The saws are about 8-9 years apart in...

    CV15S cylinder damage

    It seems an engine that old, and with the damage you described, I would let the owner decide on a new engine or continue to repair the damage engine.

    Gas Caps do seal out any condensation from entering the gas tank, despite the arguments here saying they do not

    I do not know why you get so much water in your gas chain saw tanks. I have one chain saw, one backpack blower, one hand held blower, one line trimmer, two walk behind lawn mowers, one shredder-chipper, one snow thrower, and I do not get water in any of the tanks. I DO however, refill the tank...

    Age old question, Winter Storage?

    I use Ethanol Free gas for all my small engines. I use STA-BIL for the gas only engines, and for my gas+oil I use Stihl 2-cycle oil for my mix. I do not have any problems with engines starting after a long inactive period. I run my snow thrower til dry, but all my other small engine equipment...

    Muffler bolts will not stay tight and often fall out

    I ordered 5 of them. I also heard from Stihl and they are saying once the bolts are torqued once then then will not hold anymore.(?). Which is strange since it two occasions I used one new bolt and one old bolt and both cam loose. Not too sure of the torquing story with my experience with...

    Muffler bolts will not stay tight and often fall out

    I have a Stihl SH-86 (blower/shredder/vacuum) unit and I have having a problem with the muffler bolts (two) coming loose while operating the unit. I have done the following to try to correct: bought new bolt (lost one), both came loose; used red locktite on both bolts and both came loose; I...

    Can't find 30W oil anywhere in my area, or on line.

    I would use a 10W-30 oil as it will be 30 for your use and the 10W will make starting easier in cold weather and will not affect the 30 grade provides during normal operation. I use 10W-30 for my lawn mowers, chipper, and 0W-30 for my snow thrower.

    SH86 blower run problems

    First to all who offered some great suggestions, Thank You. Yesterday was my birthday, and today I got my present: I took the spark screen out, and put the muffler (minus the screen) and the rope side of the blower back on the unit. Pushed the fuel bulb a bunch of time and pulled the starter...

    SH86 blower run problems

    Ok some information: First the fuel I use is gasoline (without ethanol) plus the silver container of Stihl oil, mixed 50:1. I bought a compression gauge and checked the compression. After three pulls it was 85-psi, and after 4 pulls it was 100-psi. I have not found any specifications for the...

    SH86 blower run problems

    I do not have a compression tester, so I do not have an answer. I tried it today and it seems like it is not getting enough fuel. Maybe a carb problem? I do use straight gasoline, no ethanol gas in my small engines. It started easy but as you said did not run enough to move the air, and then...

    SH86 blower run problems

    I have a SH86 blower that last lost power and barely would blow any air. I cleaned the air filter, installed a new fuel filter, installed a new spark plug, Changed out the fuel and put a little Seafoam in the new fuel. Noe of that helped, so now I a=m asking what did I miss, or do I have to...

    Great ethanol warning

    I have heard all of what you said above, and I believe it is all true. Especially from a chemical point of view. Since Ethanol is hydrophilic it will combine with the di-hydrogen oxide (water) and that forms an acid that does cause corrosion in the engine. That being said I have been using...

    Replace 30 year old 4 hp B&S

    I bought an engine from Harbor Freight for a 45 year old Troybilt Horse rear tinned tiller. Check the bolt pattern on the engine block where it attaches to the mulcher, then look for an engine that will match. Your piece of equipment is 30 years old so I am sure you can find one, as my...

    Replace 30 year old 4 hp B&S

    Does it have a vertical or horizontal shaft? What is the bolt pattern on the engine block? What is the shaft diameter? What kind of keyway and key does it use? What does the PTO match up with on the equipment. If you match these up and select a 4HP or 5HP engine you will have a bolt in...

    Stihl BR850 blower manual

    A picture of the whole unit would be helpful. I have worked on a BR550 and to take the covers off is a real puzzle as they are overlapping bolt holes and some inter connections. It can be done, but the learning curve is steep for the disassembly and reassembly. I had to replace the priming...

    Mower engine acts like it often does not get gas

    I checked the main jet and float bowl, and I found a bunch of gunk on the main jet. I cleaned the bowl, and main jet with carb cleaner, applied carb cleaner to the carb, held the throttle vane open so I could spray down the venturi of the carb. Put it all back together, cranked it. With all...

    Mower engine acts like it often does not get gas

    You might be spot on. It does act as if there is water in the gas. that is why I empted the tank and refilled with fresh gas, but still had the same problem. I will look at the bowl, float, and that area for water, foreign material, and see if I can get it going smooth again. Another reason...

    Mower engine acts like it often does not get gas

    Thanks ILENGINE. The fuel tank vents through the fuel cap, that is why I replaced it. That was one of my first thoughts was some vacuum in the fuel tank.I will check the fuel line for any obstructions. I still have thoughts of some debris floating in the carb bowl and it moves around and...
