I have an Englander PVD22 that I have tinkered with since purchase and finally have it running well....sort of. If I burn Lignetic Gold pellets it runs like a champ. I went to buy a few bags to get me through the rest of the cold days here and they didn't have the gold, just regular Lignetics. I notice that the regular pellets are a good bit longer on average than the gold pellets. It will run a while and then the pellets wont feed. I do not have a restrictor plate on the intake. Any ideas?
