5500 gold marquis onan gen set problems

[capt ken]

my generator will start and run at times.other times it just runs for a few minutes. I noticed soot coming out the exhaust. seems I read where this type of generator needs to have a plug removed and blown out often. any suggestions on this or where I might find the answer? Thanks, capt ken

Don't know if that will solve the problem, but yes you do have do remove a plug and blow it out. Do you have a manual for the 5500? check on the internet and if not found, I'll look it up and get back to you. ( I don't have my manual handy now)
