I had a 2-stroke blower that I finally got tired of. Why? The oil/gas mixture blew through my tray, clogging the cloth. I had to let the residue dry, and then brush the tray to open up the pores in the cloth. I ended up purchasing a vac system that uses a Dolmar 4-stroke. I no longer worry about clogging my cloth, and like others have mentioned, the 4-strokes seem to start up within just a few pulls. All you need to make sure you do is monitor the oil, gas, and filter. Me blower is almost too strong for my Gold Buddy Mini. I end up running it at a very slow speed, and it works wonders puffing the material. CaleyAnn
