Ohhh, another thing, during the pre-season clean-up, I broke my cheap vogelzang baro damper. I took it off and never replaced it. I only have an MPD now. My stove seems to run better w/out it.

You taking notes Lightning^^^

It was mentioned about replacing the gasket on the top cover. I, too, am new to coal burning and recently bought a full size Chubby. There was no gasket under the top cover and does not appear to have a groove for a gasket like the feed and ash doors do. What size and type gasket is recommended for under the top cover? Rope? Flat? Size? Thanks!

Just looked at my older Chubby and I can clearly see a gasket between the top and the barrel. I thought that the cast top had a groove for the gasket but I could be wrong. I would call or email Larry Trainer for some advise. chubbystove.com

Thanks for the quick reply! Actually, I have emailed Larry Trainer, asking about gasket sizes, but haven’t yet received a reply.
Since you have a top cover gasket on your old Chubby, any idea what size and type it is? Thanks again!

I think my stove was built in the very late 1970's. When I bought it (about 3-4 years ago) I took it all apart and replaced some parts and all the gaskets. Not certain about the top gasket size...I'm guessing 1/2" rope type gasket.

Larry will usually get back to you by email within a day or two. If it wasn't the weekend I suggest calling tomorrow.

I am currently only getting 7 hours. Whose coal are you using? I use TSC and thought it was the coal but maybe it is the gaskets.

I had a bit of a burn issue a few days ago and don't know what it was. It started when I came down in the morning. The fire was burning low, side of the barrel temp was around 200. I coaxed it back by opening the ash door and MPD. After it refreshed some I added small amounts of new coal, let that catch on and repeated this until I thought I had enough fire to do a shake down. Everything seemed jake after shaking and flossing, eventually building up the coal bed through the day and all the while giving it a generous amount of primary and draft air. About an hour or so before bedtime I opened the ash door and MPD to get the fire going strong for a topping off and after the topping off caught on I closed down the MPD and left the primary open about eighth - quarter of an inch (overnight temps were going down to high, negative single digits). Next morning I got up to the same low burning fire. Maybe one third of the bed was lit. I nursed it for an hour or so and because I was packing up to leave I let it go.

Not sure but maybe all the air I gave it during the day hollowed out the coal bed ???
