Hello folks
i just replaced the "y" throttle cable on my 91 2x4 350 trail boss and now it really smokes heavily just wondering how to properly adjust the cable to the oil injector pump?
thanks

 

On the old 94 400 you just had to line up the mark on the cable wheel with the pump body after you adjusted the slack at the throttle. 350 has a cutout in the wheel that lines up with the mark on the body according to one other member who posted some time back.Plus I can't remember on the 350 if it does or not.. Early manuals are kind of vague on the 350. Here's the image of the 400 pump for reference.You can barely see the mark on the pump body.Plus it's a little on the rich side.

 

great thanks for the reply, that helps. Now i just have to get the cover of the body again without stripping the bolt heads haha.

 

If you just replaced the split cable and not the oil pump adjuster and lock nut, the setting might be pretty close depending on the cable length of the replacement.Plus excessive smoking may not always be because of pumping too much oil. A worn needle and seat in the carb allowing too much fuel can cause it to smoke more plus accumulated oil in the exhaust pipe can do this also. Had a lot of this on the older machines that people thought were over oiling but the problem was something else. Hope it's just set too rich and adjusting solves it. Plus changing to a good synthetic "smokeless" oil if you haven done so might help.

 

i think the needle is seating well because i rebuilt the carb before i changed the throttle cable and it was mixing perfect. I haven't checked the exhaust. I think the quality of the oil may be contributing, i"m running cheap stuff right now. I'll open the pump tomorrow to see where the marks are lining up.

trying to upload a pic not sure if it worked or not. just wanted to see if i'm looking at the proper mark on the pump body?

 

Yes that's the mark on the pump body for the 400. As you notice it's set a little rich. Again the 350 may be a little different on how the mark on the pump wheel lines up with the mark on the body.The manual is vague on this and I can't remember as we sold way more 400s than the 350 that was only out for 3 years.
