    I'm once again havin problems w/ RMs decidedly proprietary jet, it simmers like crazy, but even after 20 or more pumps, I cant get the flame tips to go further than 3 or 4 mm above the flame ring.

    I swaped for a "primus/optimus" jet, and it DID techincaly work, but at low out put especialy, it wld "puff" it's self out. Even on high output sometimes.
    help?

    Might get mine out and check the jet size for you's tomorrow.And fire it up
    Like Doc would say. "I got one and mine burns perfect "

    Yeah got mine out and it started up good as gold :D

    Hmm somewhere between 11 and 13 thou is the right jet size.
    13 too large to fot in the jet and 11 to loose. Haven't anything else at the moment to mearure with sorry about that as havn't a guitar to rip a string offa.

    well, it's handsome. As the pix show, but this is the second one w/ this....erm, problem.
    Now, if I remember correctly, I can put my 210 burner in the RM tank, but, that still does not allow for both my 1 pinters to run at the same time. (all the others are up North)
    Mayhaps I shld sadle up, and try to get me another 00. or even a Svea 121, never had one o those. :p

    Try cleaning or enlarging the jet a tad.
    Sounds like its a bit tight or burner blocked.To me anyway.

    I seem to get this problem with my RM 210 copy as well. I'm not sure what jet is in it though - I'll check and report back.

    It seems to burn more to one side, though it is not really all that yellow. Jet likes to clog up a lot too, but then it hasn't been used for about 30 years until it was revived yesterday...
