Good job, that's a lot of time on bench work does that ever become an issue with the time cost in regards to charging tie customer for that cost , I guess my point is a lot of garages shops will probably just say you need a new one and not even this with it because of the dish work right would be too high for the typical customer to be ok with paying ?

Remove spark plug, piston bottom center,10 lbs air pressure into top of cylinder through plug hole, then scrape exh port. No worries of carbon into cylinder that way. I've done this hundreds of times. 30 years at the bench in dealerships. Retired now. btw - I totally enjoy your vids. chickanic's pretty awesome too :) another btw - running consistently at less than full throttle will also build carbon in exhaust system.

You can also use a small handheld torch to burn the carbon out. What I did was to bring the piston up to a point where it blocked the hole off and gently used the torch to burn the carbon out. Try not to overheat the area too much. Do a little at a time and let the area cool down before going any further.

[@Mechanicturfgear]

Great idea with the seafoam . Happens here on the course all the time . To much idling and half throttle usage I find causes half the problem. Tried doing the sea foam through carb as you said and I think it may have burnt up a few engines ( I’m thinking lack of luberation) ( or they put straight fuel in) I also burn out the mufflers with propane or Benzen when I remove them. Just cause the screens not plugged I’ve found the muffler to be plugged up also to almost tar .

[@mikemccabe1324]

The Chevy dealer uses sea foam to decarbonize. After a sea foam soak on a warm engine they start it up they drive it to get it out of the shop to avoid the de-carbon smoke. That carbon in a car is emissions/crankcase return to the intake of the engine. That’s why I installed a catch can on day one of my Camaro. I get about 4oz of distilled petroleum out of the catch can every 4000 miles. Otherwise that distillate will gum up the intake.

[@mikemccabe1324]

I warm the engine. Then remove the plug and go to top dead center and fill the head and let it soak. This soaks the piston ring really well.

[@fredpierce6097]

I enjoyed the Smoke Show dude! 😂

[@ronnieicard]

Another thing you can do is take Seafoam or Marvel Mystery Oil and a small paint brush and brush Seafoam or Marvel Mystery Oil on the carbon and let it soak for as long as it takes to loosen the carbon. This will also allow you to use a hard plastic or wooden device to remove the carbon instead of a metal device. This helps to reduce scratching the piston. Depending on how thick the carbon buildup is, this may take some time and may require repeated applications of the Seafoam or Marvel Mystery Oil. Using this method, it took almost 8 days to clean an Echo trimmer one time. The Echo trimmer was also three years old and had never been cleaned. You could also turn the port straight up and pour in Seafoam or Marvel Mystery Oil to fill the port full. I haven't tried this yet. Let it soak for a few days and pour it out. Be sure to raise the piston up so that the rings are above the port and use the piston side to seal off the port. This should minimize any carbon from getting down into the crankcase.

[@konstantinusstoyanov9749]

Would you also check the spark arrestor too? That hot soak is what I use on my mower. Works very well.

[@LaMusicade4]

[@braddempsey6930]

Hey mower medic, do you reckon running too rich a 2stroke mixture causes that kind of carbon build up, or is caused by using cheap inferior brands of 2 cycle engine oil?

[@garyalensr]

Wooww awesome he answered your question. Must be super busy to take 2 minutes at the most to answer you. I guess these KZbinrs don't realize we're why they have channels.

[@imanolberecibar]

Another major reason for the carbon build up is running the engine at low speed and low load, the engine doesn't get hot enough to burn the fuel and oil effectively and they pile up at the exhaust port, muffler and spark arrestor as carbon

[@mikemccabe1324]

Red Armor 2 cycle oil. Just bought a six pack and try it for a season on all my equipment. I’m using ethanol free boat gas as well.

[@latestplague3762]

Yeah running to much oil causes this and like the other commenter posted just feathering the trigger and never running the engine at higher speed causes it as well because it's not getting hot enough for burn off. I now mix 40:1 on my equipment made 25+ yrs ago and 45:1 on all my 2 stroke equipment thats newer and calls for 50:1. The old mentality of more is better does not work because of how much better these new oils are but I still err on the side of caution. Another thing I do not do is buy cheaper branded oils Husqvarna xp or echo red armor both are affordable good oils. No matter what you run or how you run it there will be carbon build up eventually over time I'm not a big sea foam fanatic but injecting a LITTLE maybe twice during the season like he did here will help prevent a large build up. I have also mixed small amounts of mystery oil with my gas aswell. Nothing compares to actual maintenance of equipment but these additives in moderation still have a place for these small engines.

It's supposed too, I watched a video where one tank of red Armor 2 stroke mix cleaned some carbon off the top of a piston on a chainsaw. Just 1 tank did it so I can imagine using it daily you'd never have carbon build up since its suppose to remove carbon anyway.

[@abiodunamisu1230]

Is seafoam like brake oil

[@wallacetom1]

I see in this video that you ran the engine briefly with no muffler in place. I tried this on my Poulan Pro BVM210VS . As I pulled the starter recoil it seemed like it was running for a couple of seconds each time I pulled the recoil. Can it be that the muffer is so packed with carbon the engine will not start? The spark arrestor looks clear but cannot be removed since the muffler is sealed. The exhaust port was not that bad as far as carbon . I did try to remove as much as I could. Compression is 105 PSI. Spark is good. I have tried two different carbs. ZAMA C1U-W45 Fuel lines new, fuel filter new and primer bulb replaced. I see on other videos to check the head bolts. Good and tight Any idea of why this leaf blower won't start?

Not disassembling the cylinder guarantees this loose carbon getting sucked into the crankcase through transfer ports and getting into your upper and lower rod bearings as well as possibly scuffing your cylinder and piston. Not good! Take his advice at end of video and remove the cylinder and do it correctly. I tape inside of cylinder at exhaust port and use seafoam. Soak top of piston with seafoam ensuring ring/s and grooves are carbon free. Use good synthetic or synthetic blend oil. Husqvarna makes a great 2-stroke oil for these type of engines. Heat, a crappy oil, and set way too rich make carbon accumulate much quicker.
