Cleaning carb on smoking Stihl

[spudulike]

OK, welch plug with red sealer....LEAVE IT ALONE, you will not be able to get a new one punched in and sealed well!

The carb surfaces are fine, a light rub of grease or oil on the gasket surfaces can be used but not necessary.

The needle and spring - just change them both. A slack or short spring can give a much lower pop off, trouble with flooding in hot weather and sluggish throttle response. A leaking needle valve will give flooding.

The "valve jet", I am assuming you mean the check valve.....I would be careful in taking it out and refitting a new one. They sometimes fail and go open rather than sealing one way, there are ways of testing them but it is fairly unlikely that this has failed as a saw will run if it is faulty but it will be very rich and will not idle at all. I change, at a guess, 1 valve every 50 - MS200Ts I do (similar carb). I only change them after testing them.

Happy to leave welch plug and check valve alone. Have replaced needle, spring, strainer, diaphragms and gaskets. Think that concludes the evening's entertainment - time to put it all back together!

Well, let's not carried away - no guarantee it will work after assembly! ?

Firing up any engine I have worked on always makes me think of this..........

We looked young when we watched it the first time too I reckon...

Would that be the first, second, third, fourth...........etc time we watched it........one of the best!

Gave saw, sitting in pieces on work table, several hard stares today as i passed. Nothing happened. Looks like I will have to reassemble it myself after all. ?

Hard stares....hard stares......bugger that, get lively with the harsh language and if that doesn't work, break out the hammer!
