Easy to follow and thorough step by step tutorials do it yourself (DIY) to help you with your broken lawn and garden equipment including snowblowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like a chainsaw, weed eater, weed wacker, string trimmer, grass trimmer, line trimmer, hedge trimmer, strimmer, brush cutter, leaf blower, or four stroke, four cycle units like a lawnmower, wood splitter, lawn tractor, snowblower, pressure washer, generator or a ride on mower that needs parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.

It is better to use OEM parts when doing this repair and avoid using old engine oil for your bar and chain in your modern chainsaw!

[@REDMAN298]

I don`t have confidence in the new stihl parts. One year old and plugged screen and leaky bar hose. I refuse to use their over priced oil.

[@donyboy73]

@@REDMAN298 i don't use their oil either

[@johngrossbohlin7582]

“Real” bar and chain oil contains ingredients that make it stick to the chain better than motor oil so the bar and chain will last longer and not get as hot. Used motor oil has contamination and has likely deteriorated from heat which don’t help your bar and chain life. Saving a few dollars in the short run will cost you in the long run...

[@REDMAN298]

[@LUMBERJAX0505]

Good video mate.. after use before storing my saws i open caps on oil and fuel to relieve any built up pressure to maybe help prevent leakage.. weather this works or not doesnt matter to me its not hard to do.. or its just all in my head and then that doesnt matter either... or does it..

Hi Don, thanks for all the great info on your channel, I now do all my own repairs and rebuilds thanks to you. Own 15 Stihl saws and yes the new caps are a pain. I take them off periodically and clean them in gasoline with an old toothbrush then compressed air, and that helps them last longer. But the saws live on top of a piece of cardboard, everywhere they go. Keep up the good work

[@alvar891]

Had the same problem on my 353 but wanted to quickly get it done so i cut a cylinder shape piece off a rubber clove and set it around the loose plug going in the body of the saw. Fixed the leak for a few months now. Ofcourse it is better to replace it for a original part. Mine was just something you do at home for a quick fix. Now i have that problem on a unused 357xpg i managed to get that has been sitting in a box for 9 years. My 353 was also around 13 years old when the leak came. Guess time just kills the rubber.

[@sailme2day]

thank you Don , great tips. a few thoughts. I keep a rag or oil pad in the bottom of my case to catch any oil. When I take my side cover off , I clean with brake fluid , let dry , then spray the inside with some non stick aerosol . really helps reduces the saw dust build up !!

[@tedjohn441]

With the Stihl caps once they are put on wrong they won't seal properly again. Make sure you live up the arrows and turn them gently. It shouldn't take much force to twist. I am not a fan of these but I have had to teach myself how to use them. You can also use a silver or gold sharpie to mark the cap and the arrow so it is easier to see when you line them up. The down side to that is you have to do often because the fuel mix and bar oil makes it easy to wipe off.

[@jamesrene7509]

The oil is operated off of pressure so when it starts pumping oil it creates a vaccum on the line so it's being syphon fed after using remove the oil cap to depressure the system worked on mines

[@LukaArtelj]

*stihl toolless oil cap is leaking because you have dust and debris on the seal, clean it and it wont leak*

[@thieltge]

One cause of my oil leaking that my dealer educated me about is filling the oil tank up before putting the saw away. I used to fill both the oil and gas after every session, so that it would be good to go. He said not to do that because during the variation in temperature during storage, the oil will expand and contract, and if the tank is full there is no place to expand except out of the oil line. If you put the saw away partway empty, then there is air space which can compress and accommodate the expansion and contraction. Since I started doing that I have no more oil leak problems.

[@Urbicide]

I usually shove some paper towels up the the clutch cover to help mitigate the eventual oil puddling. I collected old chain saws for a few years. The old saws in the best condition were the ones caked with sawdust & bar oil. It's like chain saw cosmoline. If a saw is put up for an extended period, absolutely spotless, it is far more likely to suffer from corrosion. Never leave a magnesium-crankcase saw on a concrete or dirt floor.

[@unclebs4732]

Awesome tips, thanks

[@LukaArtelj]

*stihl toolless oil cap is leaking because you have dust and debris on the seal, clean it and it wont leak*

I Use Old Changed Vehicle Engine Oil But I Always Use A PPG Paper Filtered Automotive Paint Funnel (2) Times To Catch Any Debris And Yes I Use A New Filter Each Time And It Has Been A Difference Between Night And Day And Never Any Type Of Problems With Leaks Or Blockages On Any Of My Saws Oilers

[@Channel0002]

Are those the correct parts for the 350 as well??

[@toddlinne6325]

Would you happen to know the part no for the oil line on a 362xp?

About those flipcaps, they work well but it needs to be clean around oil\gasoline tank hole, they won't seal right if there are any dirt, saw dust, sand.

The China parts are cheaper for a reason , quality is not their top priority .

[@LukaArtelj]

*stihl toolless oil cap is leaking because you have dust and debris on the seal, clean it and it wont leak*

[@itstimetounlearn]

Ahh, yes but that doesnt mean it is not a priority at all. You need to find the right vendor. My go to #1 aftermarket chainsaw parts guy is a Chinese vendor. His parts are equal or better than OEM stuff at a fraction of the cost. The only issue with using him is delivery time, but other than that parts are superior to what you may be used to from overseas vendors.

[@carter83419]

Hi Don, hope your staying safe. I use a lot of Stihl gear and run a small 211 and bigger 261 chainsaw without a problem. But I have a full Kombi set up, because it’s brilliant and well worth the investment. From day one of the pole pruner attachment, it’s leaked oil constantly. I’ve replaced the tootles cap a couple of times and cleaned out the the feeder line inc the sprocket area. It’s still leaks oil to this day. Any ideas from yourself or any of your fellow viewers would be welcome. Thanks!

It doesn't leak bar oil at all. Has never leaked any oil. I can wipe it clean after using it and put it on the carpet in the back seat of my vehicle and my carpet doesn't get messed up at all. All my newer chainsaws leak bar oil to an extent with one that will leak all the oil out when put away over night.

I do have one of those leaky saws. Just love the saw and there are several vids about fixing the leak. Pull the pump off, get pump and hose super clean with gas/alcohol then reassemble with thin layer of gasket sealer at hose and pump connection. Haven't done it yet but leaving oil cap loose preventing daily temp pressure changes seems to help a lot for now. Bar down, cap up.

I can see why Stihl wanted to replace the oil and gas caps. After all, the old style worked great for about the last 35 years, so yes it's totally time to replace them with an over-complicated design. I can just see what's going to happen the first time most users can't get the cap off with finger pressure. They'll reach for a pair of pliers and snap off the little plastic tab on the cap.

So what is the biggest cause of the metal plate bending?

[@scottfirman]

That would be caused by jamming the blade in a tree and twisting it out. A stick getting dragged into the chain, or abuse. I usually see more leakage from older chainsaws with hardened oil lines. I cannot count how many chain saws I see with plugged oil ports on the bar. It's as simple as removing the bar. I swear people are afraid to maintain their saws. They bring them in with burned warped chains and bars because they run them without sharpening or cleaning them out when done. I find so many free ones like that.
