diamondred 63 #1 Posted February 27, 2015 I have a Wheel horse 518 auto with an Onan engine. Has anyone modified their carburetor to use an adjustable main jet? Or.. is there an adjustable jet kit available? Thanks Share this post Link to post Share on other sites
boomers_influence 106 #2 Posted February 27, 2015 diamond please list the 146-xxxx # from the side of the carb, on the throttle side. then i can tell you if yours will accept it. WHY, do you want the adjustable main jet? boomers_influence@yahoo.com 651 437 2826 thank you. boomer ( the used onan engine parts guy ) Share this post Link to post Share on other sites
diamondred 63 #3 Posted February 28, 2015 Its under a tarp right now with 5 inches of snow on it, and not gonna have a number anytime soon. I can tell ya its on a '88 518 auto, which is going to be converted to an 8 spd in the spring. Winters are below zero and Summers are in the 90's.... I want to be able to adjust it.

boomers_influence 106 #6 Posted March 7, 2015 diamond i do stock that kit. ( 146-0327 ) WHAT, actually is the model and spec# of your engine? i do have in two NOS carbs of the same # as yours. they have the LARGE venturi, ( # 238 ) but a SMALL main jet ( # 127 ) usually a # 238 will be # 130 to 134 main jet. please call 651 437 2826 thank you. boomer Share this post Link to post Share on other sites
motodinosaur 0 #7 Posted December 31, 2016 do you still have any of those kits available Share this post Link to post Share on other sites
boomers_influence 106 #8 Posted December 31, 2016 moto i believe that i may have one yet. these kits were mainly for gen sets in motor homes. if they traveled across country it would come in handy. because of elevations from below sea level to 6000 feet. for the average garden tractor they are NOT needed. boomers_influence@yahoo.com 651 437 2826 M-F 10-7 S-S 12-6 cent time. thank you. boomer ( the used onan engine parts guy, also NOS and new ) Share this post Link to post Share on other sites
motodinosaur 0 #9 Posted January 2, 2017 thanks boomer i'll call you tomorrow I live in Sheridan Wyoming the tractor might go from 3900 feet to 6000 feet depending on job to get done Share this post Link to post Share on other sites
boomers_influence 106 #10 Posted January 2, 2017 moto i will need the 146-0xxx # from the throttle shaft side of the carb. they will not fit the later model carbs. thank you. boomer Share this post Link to post Share on other sites
