reading spark plugs (running LPG)
hi guys.
changed my spark plugs today after 12.500 miles.... keep in mind I run LPG in stead of regular gas...but what can youguys tell from mypics:   number 2, but especially number 6 have thick black stuff near the base and they all seem to have some sort of chalk of calcium deposit on it. the color isnt very clear in the picture but they are all light brown to white-ish

Re: reading spark plugs (running LPG)
does the lpg normally run real lean .
My 400 runs rich & the plugs are opposite of yours (black & wet when taken out ) But I dont know what plugs are supposed to look like running LPG. |

The nr 6 plug looks very black and can that be from oil leak?
