Has any owned or had problems with Maruyama & Robin Equipment? I just got back for blowing leaves with my new BL 5400 SP backpack blower. The engine melted the plastic housing letting needed air volume escape. The blower was in operation for less than a half hour. This has to be a Manufactures defect. Also I have notice problems with thier Multi-Cutter Power unit MC3210, it has cold start problems and lacks needs horsepower when at full throttel. This could just be a carb adjustment. And yet another problem with bush cutter from Robin the NB281. This unit is leaking gas form the carberator into both the air intake manifold and into the exhaust, running and not running. All this equipment is less than a year old and under warranty, so I will be on the phone monday to the Manufactures, distibuters, and dealers. I guess Stihl and Echo put a curse on me for not continuing with them. I'm back using the old reliable, right now.
