Last fall I bought an old 8 HP giant vac leafloader for $ 250 with old 10 ft hose. The seller said carb neaded rebuild cause of old gass left in it then it would run good.HaHa on me I also had to replace the magnito $39 for carb kit $50 for magnito. Yea now it works I decided to get a 20 ft hose as intake and use the 10ft for exaust this is ok but the 20ft long T-7 hose from IHOZE is already falling apart plastic is ripping away from wire ducttape is working to extend the life of the hose. The 10ft exaust hose was stupid of me after hitting the impeller small sticks are easily able to pierce the tough fabric then cause jams.I can use schedual 40 super tough plastic pipe to correct this problem. while making real good time on a huge leaf cleanup sucking leaves out of groundcover on bouth sides of a 250 ft long driveway. The engin blew a hole the size of a quaeter in the case. Should I try to put an 8 or 10 HP which will cost around $500-$650. Or should I buy a bigger new or used leaf loader.Does leaf cleanup make anybody any money?
