Shuboxlover 478 #1 Posted December 5, 2013 I cleaned and rebuilt the carb (Marvel Schebler DLTX) in my dads 1954 John Deere 60 tonight. I have one question...what is the initial setting for the metering valve? Thanks Share this post Link to post Share on other sites
6wheeler 603 #2 Posted December 7, 2013 The average is 2 to 21/4 turns final setting on the metering screw. I usually start at 1 3/4 or so. And go from there. Share this post Link to post Share on other sites
Shuboxlover 478 #3 Posted December 7, 2013 Thanks 6wheeler....not to familiar with the metering valve, how do I know when it's at the correct position? Thanks!!! Share this post Link to post Share on other sites
6wheeler 603 #4 Posted December 8, 2013 If it smokes? turn it in. If it falters? turn it out a little. Did you set the Idle? I would assume(sorry) you need to set the high RPM and load power screws as well. But just to get it running? Set it at 1 3/4 and adjust til she runs smooth. Which CFM DLTX does it have? I think its a DLTX 94, but it could be smaller. By the way. You can use the similar setups for a 620 or 630. Same engine, different tins on the tractor. If you need help on the air fuel mixture? let me know Share this post Link to post Share on other sites
