Thanks Paul, yes the owner was not aware that this unit requires Two-Stroke Oil, hence the burn out.

Agreed 😎.

Thanks Dimmytihon, glad you enjoyed the vid, happy to help 😀.

Thanks Kolom, happy to help 😎.

Hi and Thanx Jefferson, Hope you found it useful.

No worries Elmer, thanks for watching 😎

Rodney Ramlochan Thanx Rodney 😀

Assuming your Spark Plug has broken off but good luck 😀.

Thanks Shriyan 😀.

Thanks Taters, and all the best with it.

Thanx Mohd

Thanks Kadomeka, happy to help 😎.

Hi Noel, this is a two stroke engine, there is no Sump or Valves as in a normal four stroke engine. The engine is lubricated by two-stroke oil which is mixed in with the Petrol. It was the lack of two-stroke oil that caused damage to this engine. Hope this helps. Regards.

@@green-crocs-fixes1520 tnx much it helps a lot.

Thanks Roman, your question is a bit too technical for me, but if anyone out the does know, please feel free to respond. The Cylinder and Piston I brought came as a set with Gaskets & Rings and others. Kindest Regards.

Thanks Raimon, hope you enjoyed.

Hi Ariel, Just remove the Carburettor and drain out the fuel safely. Order a Carb gasket set and use Carb cleaner.. Regards.

Hi Jackson, I tend to order remanufactured parts from Japan which are much cheaper than the O.E, not sure if that's the route you had taken. Regards.

Yes Joseph, very true😀.

Hi Reginald, not sure that I fully understand your question however, if there is too much oil in the Fuel mixture, then you cannot get an ignition to start the engine. So the Fuel system will have to be drained off. And if the Pull Cord does not crank the engine over, then there is probably an issue with its Ratchet mechanism engaging, Regards 😎.

Hi DMUSK, A high compression is good however too much will require some Spinach for breakfast! Seriously though, sounds like you have liquid fuel inside of the Cylinder which will make it almost impossible to turn over. Naturally no Spark Plug in place will leave zero compression. Suggest removing the Plug, cranking the engine a few times then let it sit for half hour. Then fit a new or clean Spark Plug. You may want to ensure that you're getting a Spark at the plug also as if not the constantly priming the Carburettor will cause a build up of fuel. Finally a faulty Carburettor may let liquid fuel into the engine instead of a Fuel and Air mixture. Sorry for the long-winded response, Regards 😂.

@@green-crocs-fixes1520 It's actually very difficult to pull if the spark plugs in but I'm not trying to start it just turning it over and there's no fuel in cylinder. When there's fuel in there its a nightmare, it broke the recoil starter and just broke a 2nd new starter. Do you think it'll be worth taking cylinder head off and looking for potential problems in there?

@@dmusk You probably have no choice Dmusk, obviously a seizure somewhere especially if it's breaking the Recoil.

Did you get the solution to this problem? I am having the similar problem...

@@cuser147 I don't think there was anything actually wrong with it, it was one of these 52cc chinese jobs and was tough to start. I didn't really know what I was doing. Have you just bought this strimmer or is it older and developed this problem??

So nice of you

@@green-crocs-fixes1520 I have a Murray m2510 and was trying to find a piston and housing. MTD claims to have one but won't show a picture of it and the price is just short of what I paid for the entire trimmer. I put a new carburetor on it, still wouldn't crank. So I checked the coil and it was getting a weak spark and saw oil and gas below piston, so I took the piston out just ro find a broken piston ring. 1 year of lite use around the house. 🤔😒

@@rodjones6771 Hi Rod, I had to do a lot of research just to find the correct parts for this as the engine is used by quite a lot of different Petrol Strimmer manufacturers, so dismantled to measure the parts prior to ordering. Would never buy genuine as the prices are too expensive. The will probably send you a remanufactured unit anyway. Regards.

Thanks Newbie, not sure if my unit had been assemble originally with Thread-Lock, can't do any harm using it either, Regards.

Hi Goran, TrueShopping BC4902

Hi Larry, eBay. It takes a couple of weeks but astonishinly cheap.

Hi Ben, type ' Troybilt Weed Eater Piston ' in google along with a Model number and see what results show.

Hi Playa, The device was running on Fuel only, no oil additive was used on this two stroke engine and this caused the damage.

Hi Bisiklete, that is precisely what happened here. The machine was used with Unleaded fuel only, no Two-Stroke Oil was added to the fuel, the machine died after a while and was able to crank easily but could not start as there was no compression. Regards.

@@green-crocs-fixes1520 what parts are needed to changebin order to used it again?

@@green-crocs-fixes1520 do I need to drain the fuel?

@@agatth Best to strip the machine down as you see here. If damaged then you will need to order the correct Piston and Cylinder kit.

@@agatth no just add Two Stroke oil once you have repaired the unit.

Hi Branislav, the engine will not start with low or no Compression, you should be able to feel the Compression resistance when pulling the cord to start the engine. You have replaced the Piston Rings however if the Cylinder is damaged then this will cause Compression issues. Are you able to feel a juddering resistance and not just a straight forward pull when cranking ? Your Ignition sounds ok but then there is the Fuel, could be an issue with the Carburettor ? Try pouring a small cap full of fuel into the engine via the Carburettor with the machine on its side by removing the Air Filter (open the throttle) then make sure the switch is off, pull the Cord slowly once so the Fuel go into the Engine. Place the unit upright, switch on and try starting the machine.

@@green-crocs-fixes1520 Yes I did this with pouring gasoline inside cylinder behind carburator , and than I tried to start but nothing, actually flame is inside but that is not enough without pressure , pressure makes to pistons goes up and down. I changed rings and pistons but I still not changed cylinder, tomorrow I will, but only that is a left as a possible reason why machine don't work ! Grass cutter are very complicate and so much problems with them always something is bad, So is better not buy some machine if is low price , because that means that is a very bad products , is better no have nothing than something what is a weak !! For quality is need to pay much more , for example about 700 $ for some average machine . Product from China , no definitely better is quite !! Parts for this cheap machine are expensive and quality is poor , that is a nothing . Carburator are the worst part . I can see a gasoline behind crankshaft on my trimer so fuel going out from cylinder down ! I don't have tools for see a compression level but problem is there .

@@branislavpanic362 the problem is not with the price of the machine as I have repaired many of these and most of them have the same Chinese parts on the inside yet branded with a high end manufacture. Also most of these are handed to me not working due to lack of maintenance or no two-stroke oil added, like the one in this video. The replacement Cylinder/ Piston kits (from china) are a hell of a lot cheaper.

Can problem with compression be in crankshaft seals ? Do you have some video about that ? No, price is a really importan when we need get good decision what to buy . I purchased one used cutter grass from Germany and I never had a problem , and I use that almost 3 years.. So every product from China is very weak , therefore is not so expensive. Japan makes the very good products , also USA makes good things and Germany . That is already prooved .

@@branislavpanic362 Branislav Panić, zamijenite cilindar i klip kao komplet kao ja i ne biste trebali imati problema s pokretanjem jedinice.

Thanks Harshani, 😎

Thanks Atilla,

I made a research and I notice the 40-5 cylinder has the same engine connection measurements (distance between screws and so on). So actually I think that who owns a machine with a 40-5 cylinder like CG430 (43cc), actually can upgade it to 45-5 cylinder (52cc) so it will became a CG520. I just boght a 45-5 cylinder to install in my CG430. We will see if it work for real.

@@JuanMiguelEspinalJimenez Thanks Juan, it most probably will.

@@JuanMiguelEspinalJimenez thanks for helping. Mos I'm going to buy a Kasei 3gc 630 or a Hecht 163 machine. it already has a 48mm cylinder. but you might try a rebuild of a 40mm to 44mm cylinder. good evening!

It looks like a 40-5
