Have a Stilh concrete saw that would start ONCE and run, but shut it off and it will FLOOD and not restart.. Got to pull the spark plug, drain cylinder, heat up the plug and reinstall.. Sure seems like needle gas valve is leaking thru or bad gasket. Took carb apart TWICE and check and could not determina a problme...... Ended up buying an aftermarket CARB on Amazon for $35. and install ........... problem SOLVED. Counting two chain saws, this is the 3rd small gas engine that has been "FIXED" by buying an aftermarket carb for $20- 35. and installing !!! ------------- Like them all, but love the "B"s. |

Can buy the carb repair kit also , and it seems they fit many different carbs . Priced one for my Johnsered 601 and found lit fits 2 other saws I have . Price on e-bay was around $4 per kit , local saw repair shop wanted $20 for kit for 1 saw ------------- Life lesson: If you’re being chased by a lion, you’re on a horse, to the left of you is a giraffe and on the right is a unicorn, what do you do?

i was considering a gaskety kit... but i thought the gas inlet needle valve might be the problem ( no guarantee).. and i had GREAT results with two other CARBS that i bought... almost a Guarantee fix.. ------------- Like them all, but love the "B"s. |

It was on number off changed the throttle arm from my old carb started right up. Put an amazon carb on my husquvarna started 2nd pull a little teeeking and it runs perfect. Been 4 years since i replaced the carb rides in the back of my yruck st the farm always starts and runs great. |

That's the way I've been solving mine, Steve... with the caveat that when I take the original carb off, I put it (with any other removed rebuildable parts) into an oval-shaped plastic storage container strikingly similar to those found containing my favorite brand of Chocolate Almond ice cream...  I haven't had a bad replacement carb YET... but at the price, I generally have two of each on my shelf. The part that makes the most SENSE (and why the OEM doesn't see fit to replicate) is that when you buy one'a them carb kits, it comes with replacement fuel lines, filter, usually a spark plug and air filter. The bar oiler pump, likewise, comes from the aftermarket in the form of a 'kit'. Now, I don't put much faith in the spark plugs, but when I go through one of my saws, I disassemble, clean it all (including the muffler!!) inspect the piston for scoring... then replace the carb and fuel lines, the oil line and pump, I scrub out the bar, flood the sprocket to rinse it out good, inspect it for damage, file off the burr, inspect the sprocket/clutch (replace it if necessary), then put it all back together with a new chain. Darned few situations where I do all that, and DON'T have a good running, reliable saw for the season. I've lost count of how many saws I have in my armory... probably a dozen... but they all get the same treatment. I USED to use my saws until they'd have running problems, THEN tear them down. I learned something really really amazing... I found that they'd NEVER give me any kind of problems when I wasn't using them. If they were on a shelf, sitting, they'd never flood or stall, they'd never have problems starting, or running... or oiling... they'd just sit there, and wait patiently without a complaint... But the very moment I took 'em out to tackle a task, I'd find problems... so I'd hafta stop what I was trying to do, and carry it back in, and go through it.  So I started carrying TWO saws... that way, if one had a problem... I could determine wether it was from a bad batch of fuel (because the other one would suffer the same problem) or from some other situation... like a dulled blade... at which point, I'd stop what I was doing, and carry them BOTH in for a rehab.  So I started carrying THREE saws... the first two for the aforementioned problem, and the third, because invariably I'd be cutting through something and the first saw would have running problems, the second would wind up with a dulled blade... so I could pull out a third saw that was ready-to-go, insert it into the same kerf, continue the cut, only to find out that it too, had an immediately dull blade.  Then I'd get a fourth saw, and stick it in there, just to make certain that the rock buried inside that tree really WAS tougher than my freshly-sharpened chain...  (is there a theme forming here?  )But really... I'll offer this advise to ANYONE... If you want to be successful at accomplishing your tasks in a swift and efficient manner, accept my offer of experience... learn from MY mistakes!!!

The big thing now is Drain the Gas , run the saw until it uses all the gas in carb and lines , leave it empty until next use . Problem is most older saws do not have that handy primer bulb like new 2 strokes do and 2 lines to and from carb . ------------- Life lesson: If you’re being chased by a lion, you’re on a horse, to the left of you is a giraffe and on the right is a unicorn, what do you do?

Just had an aftermarket carb delivered yesterday for my Stihl FS80 weed eater so I will get it going today. I had rather buy the complete carb than spend the time rebuilding one. I have used several of the aftermarket carbs and all of them worked well. ------------- Just an old country boy saved by the grace of God. |
