stinky turbo heater

[midniteblues]

I've been useing this thing for a bunch of years.
it runs on kero and I've never had no problems with it except this year boy does it stink.
i cant run it because it stinks so bad. I really havent touched it yet but i'm wandering if theres something thats causeing it too smell.
it has fresh kero but i'm thinking its not burning as clean as it used too and thinking something needs too be cleaned.my garage has more than enough air gaps too provide fresh air and its never bothered me before until now I have a smaller propane one but it just doesnt cut the cheese like this one does I really dont use it much but being out at all hours of the nite sometimes i fire it up too take the chill off

is there anything i can do too fix it?
where or what do i check?
