Spark plug is always getting oil fouled thus no spark!?

Question

does anyone know why this is? and how to sort out?

i have cleaned end with wire brush and it starts no probs only not to start in a week or so.

Answer 1

You can install a hotter plug, but be aware that fitting one that is too "hot" can do a lot of damage. Consult your owners manual or ask a bike mechanic. A spark plug that continues to foul and oils up could mean that the rings or the cylinder may be worn. Have a compression test done by a competant mechanic. That would tell you the condition of your rings and cylinders.

Answer 2

buy a new spark plug

DO NOT clean with a wire brush, you are making it track by putting lines of metal on it

modern plugs do not need to be cleaned, just replace at recommended intervals

if you fit a hotter plug you will melt a hole in your piston like I did

Answer 3

If you've got a 2-stroke, check your oil pump setting - it may be too high, or you may have added too much premix to the petrol.  If it's a 4-stroke, there may be too much oil in the sump.

Answer 4

For future reference, always give year, make, engine size and model # when asking questions. We need all of that info to give an informed answer.

2&4 stroke engines can have similar problems, requiring different repair procedures.

Answer 5

need  to  get  all  the  plugs  out  and  get  a  compressor  and  blow  dry  the  inside  of  where  you  put  the  plugs....

start  from  there,  If  not  you  have  a  heavy  leak  and  need  to  replace  head  gasket   or  get .... oil  stop  leak,that  might  work  but  still  need  to  clean  with  air.....

Answer 6

Fit a hotter plug. Charts at Halfords or Bike shops. Use fully synthetic oil at the exact ratio.
