Hi all,
I know this subject has been done to death and I have researched the replies here but I am still having problems. I have an old Victa Vantage with a B&S engine and a pulsa jet carb that I got from the trash. All it needed was an adjustment to the kill wire and all went well so I decided to clean it up, repaint etc. I removed the carby and engine and did up the base and then replaced everything. Now, when it starts, it goes to full throttle. I had full throttle control before I interfered with it so it must be something in the reassembly. I klnow the throttle spring is dodgy and I have a couple of mowers with the same engine so I replaced the springs on the carby with springs from the another mower to test that but the same problem appeared.The throttle cable seems to function properly....What else could it be? Any ideas? Could it be sucking air somewhere - would that do it??
