Tip & How-To about Garden

When it just won't start

For those hard or no start situations, before replacing a bunch of parts ,CLEAN the flywheel...a coating of rust will hinder the conection with the coil. Especially if mowers are kept outside. Worked on hundreds of units....have only had to replace plugs on a few occasions. Clean the carb...assume its had bad gas in it. I do these things first ....then if needed start looking into the other parts.

xt 500 has weak spark(flywheel magneto with ignition points).poor when cold and now won't even start.fuel fine.isolated ignition(magneto,coil and points).changed coil.points fine,resistance satisfactory except from magneto source coil(just outside specs).also inside flywheel has some stubborn rust.can you help?


It sounds to me that you have done most all of what is needed. Just take some fine sandpaper to the magnets in the flywheel. After sanding, wipe it clean, then spray it with carb cleaner to remove any possible residue. Now give the magnets a spray coating of clear polyurethane coating. The flywheel will never rust again. Replace the source coil and install a new spark plug. A plug that is carboned up can lessen spark voltage. The last item is the battery. A weak one can rob power. Please rate my answer. Thanks.

my viking dishwasher does not rinse the soap scum off the dishes


Maybe . . . remove the lower rack and invert it. Look for cracked or missing plastic coating, exposed, rusted & possibly "swollen" inner steel rod/wire. If found, remove the upper rack and look for more of the same. What you think is "soap scum" is probably rust and other iron compounds leached by the dish soap out of the rusted steel onto the dishes and the dishwasher interior. The following worked for me . . .

To clean the interior (with both racks removed), set to "No Heat" dry, then "Pot & Pan" wash and allow to fill. Open door, dump in a bottle of "Lime A-Way", close & latch door and allow to complete cycle. This should remove most rust and iron-sulphate deposits from interior. If not, scrub them with Lime A-Way and a ScotchBrite pad, then cycle again.

Racks must be replaced (Viking are very expensive, Asko, Bosch, or other lower racks may fit: check your neighbors' racks for fit), upper rack must be Viking unless you can exact-match the Asko or Bosch equivalent.

Possible fix: remove the loose plastic coating and flaking rust with a knife, ruff plastic coating with ScotchBrite, clean with rubbing alcohol, then treat metal/rust with "rust converter" (hardware or home imp store), wash with soapy water, rinse, then clean with rubbing alcohol, dry fully, coat with "high temp" (orange or yellow) silicone sealant (auto part store), covering exposed metal and a half inch or so over the plastic coating. Let set for a day or two.

A trip through the dishwasher for all your stained stainless, glasses and non-metallic coated or non-metallic decorated dishes with Lime A-Way as above (on new or "rebuilt" racks) should get the metallic scum and rust off them.
