I have a ryobi 280R blower (yeah i know its not the best make) that wont run.
Ive rebuilt the carb and changed plugs. Ive also checked out the keyway and flywheel and all are ok so i doubt its a timing issue.
The engine wont kick even if i put gas directly in the cylinder.
I have lots of spark.
Compression is around 110 PSI
Now heres where it gets interesting.This may be a little hard to describe but here goes. I removed the muffler thinking that there may be a blockage in there. When i pull the engine over and the piston comes up on compression, i get gasoline bubbles in the cylinder caused blow by past the ring. Almost like you put soapy water on a leak in a tire.
Now with this much blowby why is my compression so good? Looking in the exhaust port at the cyllinder walls i dont see much scratching. Could i have a stuck ring?
I dont want to put any more into this blower. I already have almost 40 into it. Just not really worth it considering the brand. Blower was a "Gift" to me from a neighbor so who knows how long it was sitting in his garage
I suppose i could pull the cylinder and have a look. Im going to cobble together a leakdown tester and give that a try as well.Any other ideas?
