    Gentleman

    I need to know how to fine tune my carb. (DLTX-75) The manual talks about idle and load adjustment needles, I'm not sure which is which. Also talks about grounding out tractor, what do they mean. My tractor surges at both idling and at full throttle. I know I haven't posted pics yet, but there coming, just forget to take camera with me when I go to farm. Any help appreciated. Thanks, Gregg

    You say your tractor constantly surges. Are you sure it's a carb issue and not in the governor?
    Thanks,

    Well after really paying attention to it , it kinda justs misses till you pull the choke to about 3/4 out and then it runs pretty smooth. Another gentleman said I may need to clean the passages with a drill bit. Not sure I really haven't took it off and looked real close internally yet. Supposedly the gentleman I bought it from said he had the carb rebuilt, but then when I called him he said the guy that done it wasn't to sure of himself. I'm trying to rebuild the starter now it quit working 2 weeks ago. Thanks, Gregg

    I would try disassembling the carb and soaking it in a light acid solution (carb dip). It's too easy to ruin an old carb with drilling. Once you get it cleaned up, I'll get you the screw settings. Keep us posted.

    Would Berryman's chem-dip work alright or what suggestion would you give on the carb cleaner.

    Thanks,Gregg

    I'll be in the shop, today. Been on the road. Will check to see what we use. Not familiar with the product you mentioned. Read the label carefully. I ruined an aluminum cylinder by leaving it soak too long. ;-)
