I will go out and look at the carb now where does the Impluse line go from the carb though?

Just looked at an IPL and it looks like just below and a little left of the intake port.

Thanks for the reply,
I will have to wait for the cylinder to go on before I can remove the clutch. I did not listen / forgot when earlier they told me to remove clutch and fly wheel first.
He was told that no the cylinder is not trashed that it was trasfer we were feeling? Not too sure bout that but anyway we will try to remove that as well. Where is the impluse line/ connection on the saw I dont remember seeing one? All I see on the base section is a badly leaking gas line ( told him to buy new) and the tank vent? Is it attached to the handle assembly and plugs into the bottom of the cylinder ? I would have to go out to look again but I did not see one. As far as the piston he got a price of $90.00 I think and I told him to order seals as well. Sounds like baileys is a better deal? He is still on the road and the cylinder is with him. You Stihl guys must be a special breed, He was told by two diffrent shops that if the saw came to them they would have told him to junk it.They could not believe he/ I was into it as far as I am they told him the labor costs alone would have almost been enought for him to buy a new saw. Please answer me about the impulse line thing I just dont remember seeing one?I am wondering if it came unplugged with out my help when we were taking it apart/ If so that would explain why I dont remember it? Jeff

If I remember right, The impulse line goes from a barb just below the intake port on the cylinder and fits like a grommet into the plastic that the carb mounts to. When you slide the carb onto the mounting bolts, on the bottom side of the carb, a 'pipe' should slip into the impulse line. The vent is a little plastic nipple to the left of the carb when looking from behind. On that nipple should be a small hose about 1 1/2" long with two little screws in it which act as a vent.

OK so i looked at the carb and there are two brass elbow nipples one on the bottom Fuel I think and one on the left but I am pretty sure there was no line connected to it? I cannot find a short section of line in my bucket-o-stuff so unless the line is attached to the cylinder ( very sure there is nothing on the cylinder) I have no idea what to do about that?

The bottom brass elbow is for impulse and the left brass elbow is for fuel line.

Ok but he just bought a new carb a month or so ago so would your thought still apply? and where does the impluse line go? after you connect it at the carb where does the other end go??

check post 42 and post43. It goes to a barb under the intake port on the cylinder.

I guess you and I must have posted at the same time , so there is a nipple sticking out of the cyl just below the intake? I see the vent no problem and yea It has little screws inside it. I guess I need to go look at the IPL you posted cause without the cyl in front of me I am confused.I was pretty sure the gas line plugged into the nipple on the bottom of the carb but from what you are saying and another poster( sorry cant remember his name) the bottom nipple is for impluse and upper left nipple is for fuel? is this correct?

stihl 029

My two cousins are cutting fire wood each winter to pay their land taxes each year and his 029 has given up the ghost aparently.
I just spoke to him in the woods and he said "well my 29 is all done I guess".When I asked what happened he said well it runs fine but has no power at all in the cut, so he looked down the plug hole and said " she's all scared up" His neighbor who he listens to quite closely says throw her in the trash and buy new it will cost ya $300.00 or more to put a piston and cylinder on it.Evedently neighbor just did one of his stihls and figures thats what it cost him. (Do'nt know bout that?)
I just said " hua " about 10 times as his story unfolded.How much would it cost to get a cylinder and piston/ rings for his saw do you think? He mentioned a few times I should make his my first Stihl saw repair.I have ever even looked under the cover of a Stihl I have only done my Partners.
I told him probably a jug , piston , and rings would fix him up maybe new gas line /filter plug and carb rebuild.
Then he says "nope brand new carb about 2 weeks ago, never should have changed carb's I guess after I did the saw has no power now" I wonder if he ran her too lean? Thanks for the advice Jeff

I have worked on several of these 029/290 stihls. first pull the muffler off and and remove the screen. try running saw without muffler for short period of time to eliminate a muffler problem. Muffler has to be off to pull the cylinder anyway. Ok here goes the process to get the cylinder and crank out of case. remove black top handle, remove air filter, carb, push intake boot through orange handle casing, also carefully push impulse line through hole, take off orange trigger top cover assembly, remove flywheel and coil (nut is standard right hand thread), remove sprocket, clutch(left hand thread), remove oil pump and driver, take out bar stud closest to sprocket, finally you are ready to tip the crank pan, crank and cylinder out all in one piece. before you put it back together put in new crank seals in crank and seal pan to cylinder with High temp rtv. you should be able to buy all parts online for about $100 for aftermarket. Small Engine Repair Parts | Aftermarket Small Engine Parts & Kits| Chainsaw Repair Parts. yes and ms390 cylinder will work just fine on this saw exept check with your local dealer because I think it takes a different carb.

this job will take you at least 3 hrs
Hope this helps ya

No pics eh?

I always love a stray nipple!!!!

 

[Jeff Lary]

Nope no pics my dog ate my camera last nite, And cous has the cylinder w/him so I cannot look at it. Unless that short impluse hose fell off while we were taking it all apart I am wondering if he even had it connected? The story goes about a month ago he changed out the carb to try to solve the issue and I am pretty sure he would not have even known what an impluse line is so if it fell off on him a month ago and he never saw it he wouldnt have put it back on? Would the saw run without this line connected? I would imangine no?

HELP ,... I have followed this link to the instructions and descriptions but I cannot print it out? and I really need to. This link takes me to the exact kind of explaination that I need soooo badly. Can someone send me a link to this that CAN be printed out? I would really appreceiate it. Jeff

 

[Jeff Lary]

About 10 cc bigger

MM

With baffle

Without baffle after mod

Section of muffler before mod

Section after mod

Cover of muffler

Cover of muffler after mod

It makes it alot easier to take the clutch flywheel off before you taking the cylinder off than before

I think I have enough on my plate already,...butif I do the mod you did how did you get the muff apart/ two peices? ( FRICKEN GREAT JOB BTY)

 

[VINIFIREWOOD]

If my memory serves me yes that muffler is a two piece that should just pull apart. Keep one thing in mind, you can go too far with a muffler mod. Open it up too far and it won't run right. The engine does need a certain amount of back pressure.
In my opinion, the pics posted earlier look ok for a 390 but if you stick with the 290 setup i think it would be too much. The area as in measurement or square inches of the final exhaust outlet or combination of openings should be equal to or slightly less than the opening on the cylinder. Follow?

Can you save the IPL to your computer then print it from there

Yes I do understand and will be careful.Thanks Jeff

I dont know? do you mean like I create a folder on my desktop then save it to there? then open that folder and print it? I will go back and try. I just tried it and no luck I even called our IT person and she has never seen a pdf that will not print? All set thanks everyone I got an ilp to print.

 

[qbilder]

Have you tried your print screen button on keyboard? When you are on the page you like, hit that button, then open an empty word document and paste it there. You can print the word document.

Here Jeff,
This thread may be helpful, the ms290 is pretty much the same saw.

Upon reading the dilemma about finding the impulse line. If you took the saw apart it is probably still sticking in the top cover (hanging out the back of the fuel box area). Don't know if that will help you. Upon reassembly I always install the impulse line on the cylinder before installing the top cover/rear handle. The work the tapered grommet into the carb box after wetting it with a little WD40. Did you get the saw back together?
