    Stihl 028

    Working on an 028WB which has no spark so I ordered a new module for it. Now I'm wondering if I'm going to need a different flywheel for it also. The module I took off it had a small plastic box hooked to it with two wires coming out of it. I'm not sure if the thing has points or not since I...

    Echo 440 EVL

    Working on an Echo 440 EVL which I can't get to run except on a prime then it dies quickly. Carb has been rebuilt but upon my inspection I noticed no pulse coming from the impulse line. I pulled on it and it seemed to be hooked up but I couldn't see the end of it nearest the engine. I blew...

    Stihl 017 Handle

    Anybody know an easy way to remove the handle from an 017 Stihl saw? I've already put a little spray silicone on the rubber plugs but haven't figured out where to pry on this thing to get it to come loose. I watched a video about it but the guy doing it didn't seem to know much more than me...

    MS390 won't start

    I rebuilt yet another 290 which I turned into a 390, new piston/cylinder, seals, sealed up bottom end good with Dirko, put it all back together and now it won't start. It seems to have plenty of compression, spark, fuel and pulse line okay. I tried two new spark plugs but no difference. I...

    Stihl MS271

    Just wanting overall opinions of the 271 Stihl. I have one to work on, turns out it has 90 psi compression and from what I've seen it appears the parts are a bit expensive and it looks like it's harder to work on that the older Stihl saws, like the 026, 028 etc. Wondering if it'll cost more to...

    Stihl 015L ignition

    I have to repair a Stihl 015L which has no spark. I tried cleaning the points and it still has no spark so I'm thinking the coil might be bad. I checked the kill switch and it works okay. Was wondering if I could just change the thing over to solid state, eliminating the points. The saw has a...

    Stihl 011 av leaks bar oil

    I have in the shop a Stihl 011av that runs well, looks good and is in good shape other than it leaks bar oil everywhere. The owner told me that the oil was thin because it was leaking fuel into the oil tank but I saw none of that. What I noticed was, after I ran the saw a few minutes and shut...

    Echo CS590 question

    Installing a piston on an Echo CS590 and noticed that, unlike most saws, this piston has a flat washer on both sides of the piston where the pin goes through. I was wondering if these are really necessary since most other brands leave them out. If the parts are made right I doubt if there's...

    CS590 surging

    Working on an Echo CS590, owner says it surges. I started it up and he was right, it seems to have a lean surge to it. Wondering if the carburetor might be the cause. I'll probably do a pressure/vac test on it anyway but right now I don't have the block off plates. I know those carburetors...

    Not chainsaw related but a Poulan I think

    I'm working on a Craftsman Weed Whacker which I think is a Poulan since the model number starts with 358. Anyway, the starter slips. If it was a chainsaw it wouldn't be a problem but the starter is on the front of the engine instead of the back and I'm not sure where to start on this thing...

    MS251 no start

    Currently working on a friend's MS251 that he says "doesn't run right". I tried it and couldn't get it to start at all. Anyway, he says he installed a new ignition module on it and it does appear to have spark but maybe not on time. My question is: Does the MS251 regular saw and the MS251...

    MS250

    I've converted several of the MS250 saws over from easy start to conventional but have encountered a problem with the latest one. I changed the starter and flywheel with the conventional ones, put it together and get no spark. I'm wondering if this saw takes a different module or if I have one...

    Poulan Question

    Does anyone know if an ignition module from a Poulan 2000 will work in a Poulan 25DA?

    I broke a spring today

    I didn't think something like this would happen but I was sharpening a chain for my Super 2 and the spring broke on the grinder, just about tearing up the chain before I got it off it. This grinder is made in Italy and was given to me by a neighbor before I moved so I have no idea where it came...

    MS361 bar stud problem

    Working on a 361 for a friend, involves putting new bar studs into the case. Problem is, one hole is much larger than the other one. Looks like someone has re-drilled the front hole and put a larger stud in it, now the standard Stihl stud won't fit. Is there some kind of insert I can put in...

    Homelite XL ignition

    I was wondering if an electronic ignition module can be installed on a small Homelite XL using the points flywheel or will the flywheel need to be changed also?

    SDC Carburetor

    I've always dipped the small chainsaw carburetors in carb cleaner and rinsed and blew them dry with compressed air but I'm wondering on these Homelite saws which use the SDC carbs whether it's a good idea to dip them, and maybe hurt the little check valve in them. I have several HDC and SDC...

    MS361

    Just re-posting this from the "what's on your bench" thread. This 361 is very hard to turn over, meaning it has great compression but it doesn't have the right feel to it, like it has compression while the piston is going up or down. I've had saws like this before and the crankcase was full of...

    Hard saw to pressure test

    I've done pressure/vac tests on several saws but so far the hardest one to do is the one I have on my bench right now, it's an old Homelite XL2. This saw showed all the signs of having a fairly big air leak and when I went to pressure test it I couldn't get the thing to hold any pressure even...

    Husqvarna 435

    I have a Husqvarna 435 that was brought to me with low compression. I took it apart and noticed it had a stuck ring but the piston and cylinder looked otherwise undamaged. I pried the ring off, cleaned the ring groove out and replaced it with a new Caber plus replacing all the seals and using...
