2 Stroke trimmer engine break in

[SilentType]

Recently picked up an Echo SRM-225 string trimmer from Home Depot. This is my first new purchase of 2 stroke OPE. Any pointers or procedures for engine break in? I'll be running 93 octane E0 no name gas from a local filling station/garage with VP Racing 2 stroke oil. Engine BTW is 21.2CC.

I bought that exact one last summer and I just let it warm up a few minutes before letting it rip. I was a bit unhappy with it at first because it seemed to be lethargic and have no power compared to the Stihls that I had in the past but it seems much better this year after it got a few hours on it. Good luck.

Thanks I also have a GT225 which has the same motor I think and it's good enough for everyday grass trimming around the house. I got the SRM with the intention of using a brush blade on it.

I bought a new Husqvarna 2 stroke trimmer last year to go with my Ryobi Expand-it tools. I mixed my fuel at 40:1 and then let 'er rip after a few minutes of partial throttle and idle. It starts on the first couple pulls every time and has been great so far. I use it for edging, brush trimming, tree trimming and tilling.

Ive been through about 7-8 Echo trimmers and blowers and saws. I just run VP racing 2 stroke FD oil at 50:1 and let em run at full throttle. Send it.

They are a little lethargic until they break in. Just run it like you stole it.

I’d mix the oil at 40:1 and use normally

DRIVE IT LIKE YOU STOLE IT!!!!

I like to mix the first gallon of gas thick. I don't know if it helps but it seems like a good idea

Echo Red Armor synthetic 40:1 run it as you would any other time. You want some good reading follow Iowa Performance Saws he builds and runs that blend in brand new ported 2k dollar Sthil Saws and nothing else.

I have an SRM -2620. Last year under warranty the crank case stopped holding vacuum or pressure and it wouldn’t run. They had to long block it. I was way behind on trimming at the farm my family has.

When I got the first one I broke it in easily. This one went right to WFO after timing my house at mid throttle once. It runs exactly the same as the other one so I’d send it.

My Husqvarna FR 336 is 7 years old with about 300 hours on it running 30:1 and E-zero 91. No smoke.

Try 32:1 if too smokey go 40:1

For break in, you can run any JASO FD oil at 40:1 and run 2-3 tanks this way before you transition to 50:1.

You should idle it 1 minute and then go full throttle. Do not go full throttle without a slight warmup.

BTW, echo red armor oil is excellent. So is your VP racing oil.

I have a low hours 2620T unit, running 40:1 in it, and ****, it's flawless.

Remember: running more oil, means less gas, which causes lean running.

I'm using VIP 40:1, but plan to switch to the normal 50:1 after my first batch (quart) is gone.

The difference in fuel to air ratio at normal mix ratios is pretty tiny. A 50:1 ratio is 2% oil. 32:1 is 3.1% oil. Barely more than 1 percent less fuel by volume.

My gas can currently is mixed somewhere between 40:1 and 50:1 with VP Racing synthetic JASO FD. Thanks yall for the feedback. Gonna let 'er rip in the next day or so. Stay tuned for the exciting conclusion!
