Love my new 2005 B-50 use it daily. Its come up with one quirk lately however. After pumping for a while then waiting for mud or something and idled down, every now and then the engine will load up idle rough and smoke till i rev it up then it goes away. Any one ever experience this behavior? Some one said to try injector cleaner? Can't hurt but in my experience not a miracle cure.

Yeah i figured out what was wrong with my pump today.. I was in the middle of a 42 yard inside pier column wall filling inside a paper plant and three hours in my pump quit. Well first it stalled at idle then totally died. While turning over i saw a pin hole in the fuel filter. Lucky i had the forsight to have a spare on hand and after an ordeal of changing and then perging the system of air i was back to pumping again YEEHAW!

hey i think the best way is to buy new concrete pump hose
