Backpack Blower - Echo PB-603

Hi all.
I just boucht a used Echo PB-603. I have never owned a backpack blower, but have owned many different types of 2 stroke equipment. I was wondering if there is anything in particular in the upkeep i should do for it? The only thing i could think of, like any simple 2 stroke, is keeping a good air filter in it. And running the proper gas/oil mix. Anything else?


Thanks.

Also besides the propper gas/oil mix you want to make sure you are using fresh gas. In the winter time you should run carb cleaner through the blower and aftor that run fuel stabiliser through it. Now of course they have to be mixed with gas, but all you have to do is read the label. These things mentioned will keep that blower running for a long time if you do the above. The reason many run into trouble with 2cycle engines is because they don't do these things and they get a varnish buildup in the carb which requires a carb cleaning. If you think about it, 2cycles are easier to maintane that 4cycles. Every year you should replace the air filter and the sparkplug. Allways keep the exterior clean aswell. Use anything you want. Carb cleaner, gas, wd-40, etc. Let us know if you ever need any help or advice.

Hello Resaw!

You pretty much got it...keep a clean filter in it, clean plug, and add fuel stabilizer in the off-season. Keeping it clean on the outside is a good Idea too, like Terminator suggested, but I wouldn't use carburetor cleaner to do it. It will dissolve paint, labels, and even some plastics. I also reccomend against using gas to clean it for obvious reasons.

One other item to add to the maintenence. As with all two-strokers, the exhaust will need to be de-carboned periodically. Over time the oil will build up in the form of carbon deposits in the muffler as well as the exhaust port of the engine. Muffler removal is required to service.

Ok, you all have good advice. Now you mentioned De-carbing it. I've heard of it, and attempted to fix it myself once...but i don;t know how effective it was. Basically the carbon built up enough that the engine wouldn;t run. I diagnosed the problem. Took off the muffler, and whalla. OK, so What i did was turned the engine over untill the exaust port was open, and i held the blower upside down, and attempet to scrape the exause out of the port. Which i thought was the best way to do it.
If you have a better way, or suggestions, please let me know.

Thanks

You pretty much got it! Just be careful to not scratch the piston or cylinder walls when scraping out the carbon.

I don't recommend having the port open while chipping out the carbon, even with the port side down. There is still a good chance of some carbon to sneek into the cylinder...and you don't want that. Position the piston so that it covers the port and be very careful when chipping away as as not to scratch the piston. By the way, many mufflers are not serviceable, whereas they can't be disassembled to clean out any carbon. On these muffs, replacing will be necessary.

re: echo blower

Hello Resaw:

The advice Cheese, Puey and others gave you is dead on--but I have one more tip: use Echo or Husqvarna oil with stabilizer.

The above oils need to be mixed at a 50:1 ratio but are fantastic.

Note: DO NOT mix any typical oil at that ratio. 32:1 is normal for the Echo with generic 2 cycle oils.

That said The Echo and Husky oils cost little more than generic and will, IMHO, give you a better running engine.

Regards,

Here comes the Great Oil Debate. If it is ISO/JASO certified, is it sufficient? I had a tech tell me that as long as it is ISO/JASO cettified then it's fine. So what i did was i told one of my guys to pick me up one of those squeeze measuring bottles of Echo oil at HD, he accidentally bought Home Depot's generic line of "power care" products. It had all the ISO/JASO certs, so i figured it was fine. Ummm, so i guess my question would be...is anyone familiar with that particular oil, and does anyone have any input? Bring it on, i am very willing to learn, and from now on i am just going to stick to Echo oil i think. And run it in all of my machines. It's not much more expensive.

Thanks

By the way, for snowman...The HD "power care" brand oil specified to be mixed at 50:1. In other words, 2.6 ounces to the goallon. Anyway, just thought i would add that in. Let me know what you think.

Thanks

Most of the time, you would run the oil ratio reccomended by the manufacturer of the equipment. If you run a synthetic 2stroke oil, 50:1 should be more than sufficient for any engine. There is a difference in oils. Some are better formulated, use different additives, and are more/less refined. Some are subject to make more ash/smoke than others. A quality oil will do in any case.
