When I got my 026 running at the end of last season the first thing I checked was the coil to see if it sparked. It was a saw that a friend gave to me. He acquired it from his uncle and his uncle had it as a project saw so it was missing a few things. I've had it for a while and never touched it but last season I just got the urge of wanting to get it running. Since it hasn't ran in who knows how many years since my friends uncle had I put a little bit of 2-stroke oil in the cylinder to lube the piston. After that I took the coil off and cleaned the contact area with my Dremel and a light wire wheel. I did the same to the magnet on the flywheel. Put it all back together, re-gapped it with a business card and put the test light on it. It was getting good signal so I just put a little dribble of 2-stroke mix in it and she fired off. Once I saw that it was a runner that's when I started hoarding parts to fix it up. I'm no mechanic but I love to tinker when the mood strikes. All of my gained mechanical ability is either self-taught or from helping my younger brother with a project bike as a kid. He just happened to take small engines class in high school at the time. We never got to have brand new shiny quads or dirt bikes as kids like other kids did. Anything we were fortunate to have was clapped out or beat up already when we got it and we had to fix it to enjoy it. :)
Great video, thanks...but it leaves me scratching my head. I have a couple of saws that might have a coil problem. Is there any way of diagnosing the coils further. As you know it's expensive just to buy new ones.
I had a tank vent issue along with and undersized fuel line someone had put on my 394XP. I had the carburettor apart multiple times I had the intake manifold off the spark plug out. I had all kinds of running/idling issues. Now the saw idles and run with some power! I replaced the tank vent and put new fuel line in correct size of course and replaced the cracked intake black collar. Starts everytime now. Couldn't believe the issue I had was a tank vent but it was

Tinman, I totally have loved your 394 videos. This one I can especially relate to. A 394 was my first and only Husqvarna saw so far. I was hunting for a 372 but found a decent 394 not for a steal price, but decent. It ran strong, but was harder for me to start than for the seller. Once I got it home, I found a super clean top end when I looked in the exhaust port. I also found that the On off switch was an issue, Glad you showed checking the wires on yours and also got around to the Coil. I want to check that I got my saw back tight before checking if the Switch fix helps the startup.
*NOT BEING PICKY* cut your description has a "304xp"; only reason I mention it is because this video needs to be seen by someone searching for "394" Again, not trying to be picky or anything. Thanks for the video!!!
@Tinman’s saws Hey buddy! I have a Husq 465. Ran great for a year or so until one day randomly would not start. Took it to the dealer after I changed the carb, new gas, spark plug, filter, and coil. The dealer could not figure it out either. Can I send it to you? Maybe you can help. I don’t wanna throw a new saw away.
i have problems with 394xp she has backfire i did same what u tell on the video she got too how do i fix this thing tinman FC from south Thailand the land of forest Amazon of Asia 😁😄 thxss
I wish my 272xp build trouble shooting was that easy...😂. Good that you solved it...some heat cycling and into the wood it goes. The only issue I have with Wolf Creek is the exchange rate and delivery cost. But it is what it is. Ryan is great, though. TC Mahalo Tinman 🤙🤙🤙
Hey Tinman did you film the carb rebuild I have a 394 I'm redoing hoping to see it to see the gasket you used I have fuel leaking out of the vent hole near the fuel barb thanks
i don't got time for saw politics or politics in general. im about the power range it's durable and fuel efficiency otherwise the saw can be ugly it can be colorful idc if it runs like snot cuts like a brand new saw doesn't drain a tank before u get a good ways in lets go
Oddly enough over the last year i had two coils go bad on me. One on a saw, and one on a blower. The saw was a heat induced failure after about 3 minutes of hard cutting. The blower would start cutting out at idle a bit, and break up at full squeeze. I've also experienced high speed check valve issues under the welch plug, but that's usually all bog and no juice at full throttle. There really is no substitute for time and experience. It all goes in to the ol memory bank.
A worn area on your spark plug wire CAN short out the spark, without bare wire exposed. Your ohm meter will not show this. High voltages will pass through materials that are "non conductive". The air is conductive when you crank up the voltage and current; think lighting lol Anyway manufactures make things with just enough insulation to prevent a high voltage spark from getting through; it should not be less. Personally, I would not leave a worn spark plug wire, against metal. It should not be wearing like this IMO. Some plug wires have a woven heat wrap around it. May be a good idea to add this to a plug wire with the coating wearing.
There are videos on YT to teach you how to test a coil. With electronics though, you get intermittent problems. May test ok but fails when in use. Coils and spark plugs both can test fine cold but fail when warmed up.
I had a Husqvarna that the coil died it was a few years old , took a coil off a worn out saw I used for 18 years , lasted the lifetime of the saw . 👍🇨🇦
When I got my Unknown-026 running last season I was glad I tested it for spark first. Because after I verified that it had spark, out of curiosity I had a new coil quoted at the dealer when I was ordering needed parts to complete the build. The price for a new coil was $160. I also had a new carb quoted for the heck of it as well and the carb was going for $150. For those two parts alone I could have bought another MS251 for a few extra bucks. I don't need another MS251, but two parts by themselves shouldn't equal the price of a whole new saw.
What could be wrong with my 394, need help and advice. I just took it into to have it serviced, I'm 81 and always been able to start this saw, And this spring it would not start easily and quit when turned over relating to a fuel line, which they replaced, But I still could not start it, Except this guy who I took it back to, was able to start it, but he had to really yank on it, 3 or 4 pulls, and after that I was able to start it, But this morning It coughed twice on me, Is it possible they did not set the coil gap correctly or ignored it, I suspect timing, And the other day when I first brought it home, I could not see any sign of fuel on the plug, while trying to start it. Could I be right that the coil is to far away from the fly wheel? And God only knows what else they missed in the carb
@@tinmanssaws Thanks ; I tried to reply and it disappeared, so i'll try again, I did find the problem where the company i took it to, didn't even consider it a problem, when they had a brute of a guy who could pull it extremely fast, and it started, not so easy for myself. So i used my own small brain to fix it, and i should send them a bill, What I did was look at the coil gap, thinking the closer it is the better and easier it produces a spark, When it calls for about 12 thou gap, I found a piece of paper about 7 or 8 thou, and reset the gap accordingly, and no problem, It is as easy as cutting pie to start it. I hope that helps others who are finding a similar problem with their saws, The recommended gap is what i would call maximum, not the best. make it less and find it easier starting,
Compression to a point makes power. But if you run crap gas or old gas that has lost octane it will detonate and will start smashing your piston like a hammer and chipping chunks out of it.. Do not run low octane fuel. If you can't afford higher octane fuel just stop!
TinMan U got that right, my 394xp is trashed, but it was free. Now, what to do with it? 3 corners broken, but Mahle cyl/ piston look perfect. Local welder guy retired.😮 Im 75+ , shot shoulders, fellow HD 13 Ultra jockey in Oregon Cheers
