Question about Ryobi 30 Cubic Centimeter Curved Shaft Gas Trimmer

Ryobi 2800R 28CC Weed Wacker questions

I recently purchased a used Ryobi 2800R 28CC Weed Trimmer off Kijiji.

It started right up first try, but I have a few questions that I hope someone can answer for me.

Line housing is always spinning. Is this normal? I would think it would be safer if it only spun & trimmed when I pulled the throttle?

Smokes alot? - Normal?

Loud - Anyway to make it a bit more quiet?

Thanks in advance!

Most likely it does not have a clutch which is common on cheap curved shaft trommers. The only cause for smoke in a 2 cycle engine is the oil you put in the gas.

There are two major differences in 2-cycle engines. There are water cooled and there
are air cooled engines and the oils are entirely different. Water cooled (outboard) engines run at much lower temperatures and at much lower RPM's. It is necessary for outboard oils to burn during the combustion cycle. In this situation the oil turns to smoke so that the oil is not deposited in or on the water. Air cooled engines run at a much higher temperature and must not be used with outboard oils. In an air cooled engine the oil should leave the muffler in liquid form. If the oil turns to smoke it is not able to lubricate the engine and a very undesirable carbon deposit is left behind leading to engine failure or stuck piston rings.

Since a top quality mixing oil will cost $12 or more for a six pack (that comes out to well over $100 a gallon of oil) there is little wonder that so many companies want a piece of that pie. Cheap oils no bargain even if it is free. If the oil says it is for outboards, lawn mowers, string trimmers, and chain saws, they are telling you that they know nothing about 2 cycle engines and only want to take your money.You should choose an oil whose brand is that of an engine manufacturer. Obviously these companies are not in the oil business but they want to make sure that they do not cause warranty claims from an inferior oil. The life of you engine is dependent on choosing a good grade of oil. You should pick an oil that you trust and that you can purchase on a consistent basis. Unlike gasoline, oil does not deteriorate with age. It is better to buy enough to last you a year or two than it is to change brands every time you run out.

The l0ud muffler probably can not be helped unless the muffler is rotted and needs replacing.

What is the problem? my ryobi ss26 weed trimmer gets fuel and spark &has good compression but will not start


What is the compression reading. You have to check it with a compression gauge before you can say it has good compression. Check compression with a short hose 2 cycle compression checker. Don't use one for automotive, the reading could be off by as much as 35 psi.

Trimmer head won't turn


If you didn't recently take it apart, then it sounds like you have broken the drive shaft in the neck of the trimmer. You can probably find this at an outdoor power and equipment type of store.

If you have a spark arrester fitted, it will be blocked with carbon preventing the exhaust gases leaving. It will be behind a plate bolted to the exhaust silencer/muffler. Scrape the carbon off the wire mesh carefully, until you can see through the mesh again.
