Question about Garden
I just bought a used craftsman rider ('98 19.5 hp 42" deck). When I got it, it wouldn't start at all. I've replaced the plugs (good spark), air filter, fuel filter, and changed the oil. I disassembled the carb, cleaned it out, reassembled. Then, it would fire on first attempt, run for about 5 seconds and then die out. After that, it would not fire on restarting attempts. I pulled the carb again checked passages, needles, ports, etc. Reinstalled and same thing...fires, runs for a few seconds, and then dies.
So today, I had a buddy check it out, we took everything apart again, inspected all the jets, ports, etc, reassebled and it ran. Now the problem is that it hunts and surges and also back fires from time to time. Adjusting the throttle has minimal effect on the hunting and surging however at higher throttle setting, the backfires seem to be more often. I don't have a manual on the engine (and it seems impossible to find any documentation online) so I don't know what, if any, screws can be adjusted in the governor linkage chain to settle the governor down.
Are you sure you got all the passageways in the carb cleaned out?
How did it look when you first disassebled it? Full of rust and gunk or just shellac on the surfaces?
Take the fuel line off at the carb and MAKE SURE that fuel flows freely. I have seen trash get in the tank and plub the other end up. Does it have a vaccuum operated fuel pump?
