Could be dimensions or as Phil suggested it could be your wood is not dry.
You should be getting hotter on top of the barrel. Because your not, then the temperature in the riser is not getting hot enough to consume the particulates.
That is the only way creosote can get past the riser.
If you can, get us some measurements. All of them. Depth of feed tube , length of burn tunnel roof, height of riser. Size of core (ie) 7.5 x 7.5 or 5.5 x 5.5)
What is your riser made off? Properly insulated ? What is your transition to horizontal area like ?
The 2" riser top gap, should have increased the barrel top temp, So changing it back rite now won't fix your problem. Later changing it to 3" or more is a good idea.
Length: The minimum burn tunnel
length is whatever is necessary to tunnel
under the bell. With a smaller barrel or cus-
tom bell, the burn tunnel could be shorter
without causing problems, but the bell must
never overhang above the feed.
If you two don't stop this rough-housing somebody is going to end up crying. Sit down and read this tiny ad:
