Hey Codfish, I had a brand new Saito 100 that broke two mufflers and when the muffler broke lose, it breaks the cylinder head, after fixing it twice, Horizon said they would not fix it again if it broke again and of course IT BROKE AGAIN...so I have a POS Saito 100 in a bag, I have used O.S. engines since then and have had absolutely no problems. Everyone talks about how much lighter the Saito is than the O.S. but the O.S. is a dependable work horse vs. a fragile engine that keeps breaking. And Saito/Horizon said the same thing, they never heard of this happening ever before...[sm=lol.gif]
