I have two heavy-duty gas-powered impact tools. These were used in a large mining operation on heavy equipment. The railroad uses these as well. i carried one of these in my 18 wheeler in case of needing to change out a flat on my trailer
One is selectable 350 ft lbs/ 700 ft lbs. The other is 350/1000. the 700 tool has been used numerous times over the last few years, however the 1000 tool has been sitting. Both started up but the 1000 lb tool idles ok but bogs down when you rev it up. The 700 lb tool works fine. The one that bogs acts like it is staving for fuel. Most likely the main jet is cruded up from sitting with mix gas for so long. Like I said, it idles ok and revs up a little but then bogs down.
Both have a torque selector as well as a fwd/rev selector and are both two stroke
OK an update on he 1000 unit. I bought some fuel conditioner/cleaner that you mix in with the gas.
According to the directions, I added it with fresh fuel/mix and ran it for a few minutes. The thing ran a whole lot better. It now revs up fine and holds RPM, as long as you apply throttle gently. It will probably clean up after a few more cleanouts. At least the carb wont have to be pulled and cleaned. Once I have it running normal, the price will be the same as the other unit.
These sell for over $3000 new!
I am asking $750 for the 350/700 ft. lb. tool.
I am asking $550 for the 350/1000 t. lb. tool.
