A friend of a fried dropped off a couple Stihl leaf blowers. He said the older BR400 runs, but is hard to restart and floods out. The owner purchased a used BR380 as a replacement to the BR400 and that one also don't run! Its leaf season and he needs at least one of them running asap. I thought this was going to be a quick fix, but was proven wrong. The BR400 was running well after tuning the carburetor, but now it no longer idles and the engine will not rev-up. Did I break it?
I no longer use Harbor Freight Super Heavy Duty Degreaser in my ultrasonic cleaner. Harbor Freight changed the recipe. The bottle previously stated "NON-CORROSIVE". Now it says "CORROSIVE", "do not user on Aluminum". It now damages most carburetors.

My mom has a Husqvarna blower with well over 2000 hours on it. A few years ago when I was just getting into small engines, it started running horrible and had no power. She took it a couple of places and they couldn't figure it out. She ordered a new one, so I just tore it down. That's how I learned about the spark arrester. I cleaned it, and the machine ran like new. She canceled the order and put it back into service. It ran fine for a few months, and then started doing it again.To cut a long story short, I put three spark arresters in it over the next two years. I finally got sick of it and installed the spark arrester delete package. Five years later, it is still going strong, and she has never had another issue, other than having to put a kill switch in it every couple of years.

May be adding to much oil in the fuel mix. The new synthetic oil can be run 50/1 on older machines. But make sure your machine will run on that mix with no issues.

Great sleuthing as usual. I wonder if just tightening the four jug bolts would have solved the problem? The fuel/oil mixture must first pass through the crankcase of a 2-stroke engine before entering the cylinder so the cylinder could not fill with fuel without the crankcase first being completely full of fuel. Therefore a leaking needle in the carb could not be the problem.

As to the clone carbs, my grandfather was fond of saying "you pays your money, you takes your chances". The other saying, which I'm sure you've heard, "if it had been a snake, it would have bit me". Two cycle engines are a very different breed when it comes to troubleshooting. I have had similar issues when I think, without a doubt, it's this. And it turns out it's not. Great job James.

I knew it was the cylinder gasket. I have done a few of these. They have a angle on the inside the bottom of the cylinder so you can just use your finger to get the rings in the cylinder. I put Permatex Aviation Form A Gasket on both sides of the gasket .The oil leakage was the sign. Always check how tight your screws are first. You found it but it cost quite a few bucks and time. You won't make that mistake again. There is a lot of vibration on these that can make screws loose. They usually use silicon. I use the right stuff on the crankcase haves. They very rarely go bad cause there is no gasket there. Live and learn.

Hi a hard lesson for me was also a Stihl but a chainsaw with a lot of time on it. I was not familiar with 2 stroke stuff at the time. the problem was similar the give away was when you rev it fuel would spray out the carb but still run. the root cause was the piston to wall clearance was too great and allowing blow by from the crank case. the fix is replace the piston and cylinder set.

The leak on the carb would not have helped but the gasket leak was clearly the issue. The oil everywhere was the smoking gun. Fantastic repair. That would have defeated me. Those pressure and vacuum readings must have thrown you off the scent for a while. Btw your videos helped me with my lawnmower. I fully serviced it for a fraction of the cost of taking it to a specialist so your videos do help

Happy Thanksgiving to you and yours, Jim! I just did 2 BR 400s and a BR 600 for leaf season down here in NC. Rebuilt one of the carbs and the other two ran great after some tuning and maintenance including air and fuel filters and cleaning the spark arrestors. The ONLY thing I would have done that you didn't would have been to torque the cylinder bolts and test it again before replacing the gasket. Surely can't go wrong with a new gasket, but I'm curious as to whether re-torquing would have made it run right too. Fantastic quality as always!

Hello James Very good video. May I suggest the reason your tests did not reveal any issues is lack of vibration during the tests. When running the engine would seal and leak itermittently. That is why they can be so difficult to diagnose. Your stick to it perseverance paid big dividends and you found the issue. Keep up the good work.

I don't think it matters if the piston is at the bottom point,I perform tests in this way, making sure that the cylinder is always in the lower position.I think the problem is in the bolts on the cylinder, they were tight enough not to leak when the engine is not running, but they were not tight enough when the engine is running and making vibrations, then false air could enter. Jemes himself said that the bolts were very loose,although I'm not sure, at least that's how I think that was the problem

Patience pays off and man, you do have some of it 🙂. When "running" the cylinder must have been liftet slightly from the base at each compression stroke, causing "puffs" of leakage. After those leak tests I really did not see that one coming, although all the oil seeping would indicate something like that. And yes, I really learned something here.

The plastic choke piece on that model of stihl was always one that would break on a regular basis . It took stihl years to finally get that change to a better design . When I seen all the oil around the bottom seal , I was pretty sure that was the problem . On any gas machine two or four cycles ,if they are running or not any bolts that's are relatively easy to get to I would check to make sure there tighten fairly well . Anything that's has oils or gas leaking is a pretty good bet that vibrations from running loosen things up .

Hi James. Just a thought that anytime a car engine has a split block. A dab of silicone should be used right on the joint to prevent a leak, either on intake or oil pan. So I would surmise that the split crankcase on this blower might benefit from the same treatment.

I went through the exactly same steps that you did, but, after having the trimmer work one day and not the next for years, I eventually gave up and gave it away. The giveaway was when you said the crankcase gasket was leaking and ultimately fixed the problem. I remember my string trimmer was always full of oil and I couldn’t figure why it was like that. This episode explained a lot. Great job, as usual!

James, I have a Redmax 8001 and although there’s new models, this was and still is a beast of a blower, but heavy. I actually prefer wet/damp leaves because this is so strong I can blow them forward no problem and the dampness keeps them down enough from getting caught up on any cross winds. I also use mine for snow clearing on cars and driveways when it’s a light fluffy snow, up to 2-3 inches.

From the color of the fuel, it would seem that the oil fuel ratio is not right. The smoking may have created problems with the exhaust port becoming plugged and choking the engine off. Your suspicion about the tank vent on the 400 seems most likely. Carb settings are 1 and 1 from the factory. On the 400 it might be worth pressure testing the crankcase for leakage. Shaft seals might be leaking causing the odd carb adjustment. The other thing here is with the mess on top of the tank there may be a tiny hole in the fuel line.

That's the problem I've had when stuff gets older/lots of usage, it's just worn and to fix the equipment can be quite the troubleshooting process. Not to mention some of the OEM parts for older equipment is very expensive. I recently bought a OEM carb for a Kohler similar to your late 90's John Deere for a Scag and that was almost $300. I bought an OEM ignition coil for a 2002 toro snow commander and it was $80. I don't mind clone parts but I also don't want to have issues return or deal w/ taking something apart multiple times when I know it's not OEM, especially when it's something that's a pain to put together like my snow commander.

a good test for base gasket is block off intake and exhaust, pressurize and spray with soapy water. if you have bubbles, you have a leaky gasket. quick and easy and a good test for any small engines. i picked up a couple stihl br420 basket cases a few years ago as a project and to my surprise, they both started and ran great and the cylinders look brand new. the engines are complete, its the plastics that are taken off. dont know why and didnt ask for $50. i agree with others, id like to see more two smoke vids also. thanks.

Great video, it was ultimately the cylinder base gasket the whole time, Stihl's 4 mix engines will also run poorly if they have any leaking seals. The 4 mix is a 4 stroke engine that does not have oil in the crankcase so it runs on 2 stroke mixed gas for lubrication, I have a Stihl BR600 backpack blower which has their 4 mix and I had to reseal the engine because it was running poorly. The 4 mix is probably affected like 2 strokes when the seals are leaking I'm guessing because the crankcase pulse has to operate the diaphragms in the carb. Excellent work James!

Makes sense, though hind-sight is 20/20. When the troubleshooting explored and ruled out various potential sources of the problem--including the carb via a second and known-good clone (@45:36)--I found myself thinking "ok, but what about all of that oil that had to be cleaned up (@14:54) and the significant leaking that was pointed out (@54:06)?" Two questions: (1) How can you tell the difference between a "normal" oily mess versus something that has to be addressed before going any further; and (2) was the OEM carb tried first just because it's less of a hassle compared to doing a tear-down to replace the base gasket?

I have learned through watching videos and working on these on my own you can't use caned mixed fuel in blowers you have to mix gas and oil to get them to work

Worked on a ton of those and man it seems like that was always the issue with all of them that or the split on the crankcase we would do a complete re seal of them and where the gaskets would meet each other at the split we would put a dab of hondabond or something similar to that and we never had another issue from them at all. Great fix!

I’ve had a BR400 (converted to SR400) for over 15 years. It gets a lot of use. The proper way to setup the carb is with a tachometer. Set the high at peak rpm, then down 50 RPM by going richer. Leaf blowers are always under load and cannot have there carbs set like a trimmer or chainsaw. It cannot be done by “listening” like a chainsaw.

The last Stihl leaf blower I overhauled had been run on premix oil designed for outboards ( TCM-3 ) and it destroyed the crankcase seals. The Stihl manual specifically says to not use that kind of oil. People...read the manual.

Those small engines can be a challenge for sure. I noticed the problem right away after you checked for crankcase pressure that you also needed to do a vacuum test on the crankcase. For some crazy reason they sometimes hold pressure and fail vacuum and vice versa. I actually thought the problem was going to be a stuck ring. I hobby in restoring old McColloch and Homelite chainsaws.

I am having that same issue with my handheld Homelite blower. I owned it for 3-4 years and have 34 hours on it. I replaced the original carburetor with a clone carburetor and just cannot get the fuel mix set where the engine is happy. The choke lever on the original broke off. I ended up buying a factory recon handheld Husqvarna 2-stroke blower and it out blows wet leaves over the Homelite blower. I now have 12 hours on the Husqvarna, and I like that one a whole lot more. So... the Homelite is the backup blower.

A Great Video, Patience is a virtue, Just on a side note the insulating block on the carburettor to cylinder has an impulse port/a tiny hole /passage which operates the fuel pump diaphragm in the carburettor if this becomes blocked or you loose crankcase pressure /vacuum the carburettor starves of fuel and will be unable to perform correctly or at all as it cannot suck fuel up from the fuel tank at the correct amount it needs to run properly. I have also seen hairline cracks in the insulating block which affect the running/performance sometimes gets worse when it warms up as the crack can expand with heat/cold.
