Serial number A187V06100H

This old lift was running with no concern, under light use. Not an everyday need, not an all day need.

I am a truck fleet tech, so this is a little outside my area.

It failed to start when I was called onto the repair for it. after checking the basics, it was a confirmed fuel delivery issue. Has a new tank, replaced the VFF30, and Model J. Got a rebuild kit for the CA50.

What caused the no start (i'm sure you already know by now) was the clog in the Model J. When rebuilding the CA50 there was a mess in there too.

The new Model J does not have the "balance" vacuum port that the old one did. I capped off the mixer port where it was connected. Also the Model J states.08 W.C. and the old part was.2 (makes me think it is not delivering enough fuel)

After the service, it started no problem, however it will just die. I turned in the throttle stop screw about 1/4 turn and it seemd to help, but then it stated to run like it was under load. and dies when throttle is applied. The "idle mixture" screw (large with a spring) does not seem to make a difference in its adjustment.

In its current state it hardly idles, and will die with throttle input. At one point when my sweater happened to cover the air filters inlet, it ran great, and did not die, or bog down. Now not so much. With my sweater (I'm talking just the bottom corner of a zip up hoodie) over the air inlet, it will stay running, and throttle input will not make it die, but not running well. I was able to get it to idle a little better, with the "mix screw" 2 turns out. and if I cover the air inlet it will take throttle input, If I double layer my sweater it will rev up just fine..... Sounds like i have too much air through the mixer or not enough fuel to the mixer.

I'am not sure what the issue is for sure. How does this sound to you? What am I missing, How do I make the adjustments I need to, or is something bigger/smaller going on?

Thanks for reading. I can get video and pictures if needed.
