JMW9 setup tracking problems... need help


Hi,
After almost 20 years I decided to return to analog. Looking for a good TT, found here in Audiogon a VPI Super scoutmaster with JMW9 arm in perfect condition and decide to buy it. I follow all the setup procedure: first level the turntable; then lower to arm until is parallel with the plate (to get that I had to lower the arm up to its lowest point); use an arm load meter to set up the traking force(I use a Denon 103R cartridge at 2.88g; little bit high of its higher set up of 2.8g); and rotate the counterweight to get perfect lateral balance; and finally I use the alignment jig to setup the perfect placement of the cartridge in the headshell. Everything looks OK but each time that I try to play a record the stylus runs across the vinyl and jumps half a song or more and sounds are sometimes (not always) intermitent. In inner grooves stylus track better b ut not perfect.
Maybe this is a silly question but dont know what else to try (I recheck everyhting and all looks ok) and VPI is not open until the 7th and will love to spend this holidays enjoying this grate TT. Thanks in advance

Just drop the weight to 2.5g and seems that everyhting is working perfect now: cartridge tracks several LPs with no flaws so Im enjoying my TT at last!. In a near future will try the 3 gram headshell weight to compare.
Instead of modify the cartridge with the wood case option and the extra dollars that I have to expend on that, is not better to hear from you some recomendations of cartridges that can works its best with this arm? look, Im very happy with the sound that Im getting now but, beacause is not easy for me to compare with other opptions, your experience could help me to get the best of my new TT; the idea is not to compare this unit with others (IM not going to change this TT) but to hear recomendations for this expecific configuration. Lets assume a ceiling of one thousand to expend. Thanks

Hi Jorsan. Glad that you got the rig up and running. I have a Scoutmaster JMW9 and a Sumiko Blackbird. This cartridge works well with the Scout series tables and arms and is also one of VPI's favorite cartridges, I've been told by the manufacturer.
Viridan, you're right, problem solved and now to enjoy the music! thanks to all.
Sanji,that is one of the options that Im thinking but for now as Viridian said: "enjoy the darned thing and start focusing on collecting some nice music!" thats what im going to do.
Thanks and wish you all have a great 2009 !!!!!
Sorry guys but need some help again: since yesterday Im hearing a VERY LOUD noise that sounds like a gunfire when stylus tuches the vinyl or when I rise it from the LP, and sometimes happens also when record is playing. This sound is scary and Im worry about my speakers also. Do you have any idea why?, somethin g that I can try?
Thanks again in advance for your comments
