AMC 360 won't run - Page 2

glennsea · 02-08-2010, 08:09 PM

Just to eliminate it as an issue, I drained the fuel and put new fuel in. I turned on the fuel pump but it is not getting the fuel up to the filter so I am trying to figure out how to get that done. What needs to be done?

Bleed air from fuel rail.

So far I have done the following with no change.
New battery.
New Starter.
New Starter solenoid.
New Spark plugs.
Set timing to 0 for #1 Spark plug. Adjusted a little each way to see if it made a diff.
Drained fuel and put new fuel in.
Tried starting with carb start spray and fuel in carb.

At this point it will crank up good but after about 7 seconds it starts to bog and die. If I give it gas at all it dies. I am now thinking it is the carb, maybe flooding?

Did you get the fuel to the carb? I assume it has an electric pump. Sure sounds like it is starved for fuel. If it is flooding, the needle valve on the float make be stuck open but usually gas runs everywhere wen that happens. What carb does it have? Some models have a brass filter where the gas line goes in. I have seen those stop up as well.

Why are you running an electric pump on a Carbed AMC360?

glennsea · 02-09-2010, 12:16 PM

Thank you.
I am pretty convinced it is the carb. Everything points to it running rich. I tapped on it to see if it may be a float but that didn’t do it. It has an arm that the fuel line connects too. The bolt that holds it on has a hole where fuel passes through so I am thinking of turning it slightly to “starve” it of fuel to see if that helps. I could also start clamping down on the fuel line as well so may do this instead.

I just got it a week ago and the previous owner installed the electric pump.

and what Pump? What PSI?

glennsea · 02-11-2010, 10:30 PM

The carb is a Holley 600 CFM or 1850-4. I am not sure about the pump yet.

From what I am seeing it looks like it is running rich. If it were a vacuum leak and I sprayed fuel or starter in the carb would it shouldn't it run?

bowtieman55 · 02-11-2010, 10:44 PM

has the engine had a backfire through the carb?

hunterdan · 02-12-2010, 06:40 AM

I had similar problem on my cj with a 6CYL.The float was way off and it was flooding the carb.Gas out top,middle and bottom.I rebuilt the carb for 20$ and it still would'nt crank till timing was near exact and I changed out the fouled set of plugs.123&4 plug were just black and 5,6 were wet.After new plugs fired right up.Good luck.

glennsea · 02-13-2010, 02:53 PM

I rebuilt the carb and it is getting fuel. I cleaned the plugs as they were fowled again. I reset the base timing wiht advance this time. It started a little and shuts off again.

Ray VanBuren · 02-13-2010, 03:19 PM

What size jets are in the carb? Are you sure the float is set properly?

glennsea · 02-13-2010, 03:24 PM

Jets are 66. I set the floats according to the instructions, turn the bowl upside down and adjust them to they are parallel to the copver top.
