Part #530069844
This is an authentic OEM replacement kit for use with lawn and garden equipment. Each kit includes the carburetor, cylinder, crankcase, and muffler gaskets. The carburetor gasket seals the area between the carburetor and engine block to prevent the entry of contaminants into the carburetor. The crankcase gasket prevents oil from leaking out of the crankcase. The cylinder and muffler gaskets prevent the combustion and exhaust gases from escaping. If you are experiencing common problems such as leaking, loss of compression, and poor engine performance this indicates that your gaskets may be worn down or damaged and need replacement. Carefully remove the old gaskets and thoroughly clean the mating surfaces where the new gaskets will be installed to ensure a good seal. Install the new gaskets and ensure that they fit properly.

  • Victor from SCOTTSVILLE, KY
  • Very Easy
  • 15 - 30 mins
  • Pliers, Socket set
1) While still attached to the fuel tank, I first sized up the old fuel lines with the newer fuel lines.
2) With a pair of needle nose players, I then removed the old dry rotted fuel ?? lines, from the fuel tank.
3) I cleaned the fuel tank and around the carburetor area, to insure that there was no debris, that could possibly fa ll into the path of the new fuel lines installation.
4) I then installed the smaller one of the fuel lines, so that it would be out of the way, of the larger fuel line. I Pulled the fuel line through the smaller hole in the fuel tank, with needle nose players. I pulled the smaller fuel line out through the fuel tank filler hole, attached the fuel filter to the smaller fuel line. I Made sure that the fuel filter was extended to the furthest end of the fuel tank bottom. Six inches in all. I then attached the smaller fuel line to the carburetor.
5) I Installed the larger fuel line, followed the same procedures as the smaller fuel line.
6) Both fuel lines where cut on an angle for easy installation. No lubricant was necessary.
7) I filled up the fuel tank with fresh fuel and oil, new air filter and spark plug. It started on the first pull. Amazing.

installing fuel through fuel tank wall
10 of 17 people found this instruction helpful.
  • RICHARD from BROCKTON, MA
  • Difficult
  • More than 2 hours
  • Pliers, Screw drivers
To start, remove the plastic carburetor grill. DO NOT remove the carburetor. The fuel line has to be sliced down to fit through the tank hole and get it in far enough up into the tank to grab with needle nose pliers.( need long needle nose pliers which I didn't have) I placed about six inches of the plastic tubing in the jaws of vice so t hat half of the tube was squeezed in the vice jaws. I then used a razor blade to shave off the exposed tube. I slipped the shaved end of the tube up through the tank hole far enough to grab with long tweezers and pulled it up to where I could grab it in the tank with needle nose pliers. I put light lube oil on the remaining tubing and pulled it through. It takes a steady firm pull to pull it in. Install the filter and pull the tube back down into the tank. I also used a small diameter drill bit and with my fingers slightly reamed the tube ends to ease the tube over the filter and carburetor nipples. To prime the engine, spray starting fluid into the carburetor and start. Repeat until the engine will run on fuel. It took me hours to figure this out, but will take less than an hour with this method.
