This is important and necessary on all self pressurizing stoves. Aaron, to me the flame shots don't look bad. The flame plate is glowing red, the flame is blue, centered nicely and the stove looks as if it's burning as it should. These small stoves are not really power houses. Both my 8R and Optimus 99 start out a bit anemic and take time to warm up before they run as they should. More than a couple minutes. The cooler the temperatures the longer it takes. I start with a pot of coffee and when that's done 5 or 6 minutes later then it's ready for a skillet. Somewhere here on the site an Optimus catalog states the 8R will bring a quart of water to a boil in 6 to 7 minutes and that's probably in a laboratory with no wind and ambient temperatures. Ray
I like the beer can bottom trick. But since all beer cans are not equal it is probably necessary to test some different brands and sizes. I'll get started tonight. If you don't mind messing up the bottom of the case -- fill the the priming cup with a little more alcohol than it can hold. The extra heat helps warm the fuel tank and cuts the warm up time. Or you can add a wick, it can hold a lot of alcohol and seems to extend the priming steps.
Agreed Ray, it is nice at that point but that is after priming it a couple of times. I always open the filler cap first to equalize pressure as well as rotate the knob fully to the left and close it back. Again, i can live with priming it twice or will try a bigger cup for prming.

The can bottom trick worked awesome, and it stays there like it was meant for the stove. Thank you again for the suggestion. Also, whoever said beggars can't be choosers, they were wrong. I have to ask another question to all. I have a Korean Shinabro 8r clone. Works great but the fire shoots out more on one sure than the other. I know it is not the fire spreader and the injector and the whole arm seems pretty straight up. And no, not the wind either:-) Any ideas what it may be? Not a show stopper but sort of a mild case of OCD. Here is a pic of it next to my Russian Primus stove.
@Aaron Mitchell If everything is straight, it could be the jet (the hole in the nipple). If you have a very fine cone or ball shaped grinding tool, gently round the very top of the jet (only a few thou.). Then make sure the jet is clear, and see if that helps. Cheers Tony
Aaron, my set up on the Russian 8r is a wind shield and shield for the tank made from copper. It tarnishes quick but for a user that's ok. Also it was at hand so I used it. Cheers Rob
