I need help with my 938SD on my F134 CJ3B. It leaves a pool of fuel in the manifold after running which makes hot starts a rich smoky ordeal. Fuel also leaks out of the bottom when I shut down. I'm unable to get the float setting anywhere near 5/16 or 9/32 with out flooding. It is currently at 13/32. The float valve is all metal and silver in color and is not Viton tipped. The last two rebuild kits I have done came from the Carb Shop in Missouri. My fuel pump is from NAPA. It has no glass bowl or vacuum stuff on it so I will need to verify the fuel pressure for you. I don't have the gauge for that so I'll get one and do that and get back on that. Also the vacum is a paltry but steady 14. I've had this carb for a long time and it has served me well. I have suspected it may be due for shaft and bushing work although I'm not experienced enough to tell that physically. The idle speed tends to increase as it warms up. The jeep is running remarkably well for the issues the carb has but Im tired of washing my cylinders down with fuel . Thank you for any advice and I hope your Thanksgiving will be great. We are expecting rain here in the desert.
My float is not leaking and appears to be in good shape. I did find that my pump diaphragm has a small crack forming which was not visible until the fuel dried on it. I took a picture which is visible at 12 o'clock. I can see light thru this so hopefully that will explain the fuel puddling in my manifold. I have a new kit coming from Mikes to address that problem. I measured 4 pounds of fuel pressure just running the starter only. When I get this back together I'll readdress that and see what i measure when its running.
I finally had time to get the kit put in. It cleared my hot starting problem up and it fires instantly when I hit the starter after hot starts. This kit came with two different float needles and seats. The shorter seat which fits my float pin height came with a solid needle. The longer seat which does not fit my float pin height came with the spring loaded needle which doesn't fit in the shorter seat. I need to do some more road testing as I think I detect slight stumble or surge at cruise. My float is set per my instruction sheet for kit K1111 which say to use setting #2 (15/32) for resilient tipped needle. I assume this is viton tipped. Both needles in the kit are viton tipped.
The jeep is running good other wise but vacuum is still a steady 14. I can get the idle down to 500 rpm cold but when hot I struggle to reach 750 Rpm.

rickg: Kubota Orange ignored Annie when she was in the market for a compact tractor so no sale, JD Green treated her seriously and made the sale..

64cj5: Had a car dealer treat Ruthie that way when she went in to ask about the new Rubicon that had just come out. The sale's man told her she could not afford that Jeep. No sale that day. We have not been back to that Jeep store.

m38mike: A friend's father died, left her with a Kubota with a burned wire harness. She gave it to me to use if I would replace the burned wires. It's on my to-do list. Someday she'll want it back, but I've got it for the foreseeable future.
