Generic Made in China eBay Chainsaw - Spark Plug

Tom Bowman · Jan 21, 2020

I ordered one of the cheap unbranded 10-inch chain saws on eBay, as discussed on YT a while back. Looks OK so far. (I haven't started it yet.)
I usually replace the no-name spark plugs in the made-in-China engines (I have others in other equipment) with NGK. However, the plug is so tight I can't remove it.
Any trick to removing a spark plug from a chain saw? Will running it to get it hot be any help? I didn't think penetrating oil would reach past the seal to the threads.

Anything you try risks damaging the head. I'd run it til it won't run no more then fix it.

You might try a thin wall long socket. 5/8 I believe.Not the regular plug socket.

Use a good quality oil, mix it 50-1, and don't leave it idle, and you should never have to take it out! I have 4 gas chainsaws, oldest is 48 years old, don't remember the last time I had plug trouble, been over 20 years. And I use them all some each year, I know we have blowers and weed eater 15 years old that I've never had the plug out of.

Thanks for the responses, everyone. Sounds like a plan.

Hello Tom Bowman,

You have a matched set already! A no name saw with a no name plug, Just run it till...??

As long as it works I would leave it as is.

That said, the key to removing plugs from a Ford head without breaking them is a 3/8 impact.

I'd run it the plug might outlast the saw.

(quoted from post at 20:45:00 01/22/20) I'd run it the plug might outlast the saw.

That's very likely, BUT: if the plug DOES outlast the saw, I'll for sure want to remove the spark plug, so I can use it in something else!

Seriously, thanks to everyone for your advice. I'll try the saw this weekend.
I thought there was a thread about these saws on YT, but I haven't found it. I'll try to post there.

Only advice I can give is DON'T try to remove it when it's hot. The sparkplug's steel threads will ruin the aluminum threads in your saw.

Hands down, impact is a day saver when nothing else will do the job. I use them exclusively for large and small jobs. Have half a dozen, ? drive down to light duty butterfly lever activation, Pneumatic and just got a HF electrical on sale for $70 vs $100 regular price with cupon. Bauer or something like that brand. Have had some difficult removals and never have I had a bolt twist off with an impact......course penetrating oil goes without saying.

Agree with waldo but what I do is put that socket on the plug and Snap it.! Havent stripped one yet. I highly recommend NGK plugs. Those Japanese and china engines just love those plugs. Had a little 800W Chinese generator that just up and quit. Stuck a NGK from one of my garden tractors in it and Bingo!. So many of those engines use BPR6ES for the 8hp and up. The smaller engines use BPR5ES. Don't forget a dab of copper neversiez. Still thinking. Squirt a little penetrating juice on it first.

What brand is your little saw? I just googled small saws and a Tanaka poped up for $52 and free shipping! If I needed one I wouldn't hesitate!

Sorry, Russ, I just saw your post.
The saw literally does not have a brand name on it. There's a sticker that says "CS2500", and the manual has something similar. It was $86, including shipping, on eBay.

If you google cs2500 chainsaw, you'll find that a company called Timberpro sells them for about $90. Might be what you have, or might be a coincidence.
