I am trying to get my CJ2a running but am plagued by the carb flooding my intake with fuel
With all the reading i have done my mind is mush.
I have two Solexs. One original and one i got online used as a part unit.
The original one was missing a brass plug on front, but i found out the plug was included in the rebuild kit, so i just rebuilt that carb,
the parts one i put on the shelf.
The rebuilt carb i put on the motor and just seemed to flood. Even doing the proper startup procedure with the choke circuit.
I opened up the second parts carb and cleaned it up and then put it on the jeep and i actually got it to fire and run for like 3 seconds, then it just stopped and flooded the intake like the rebuilt one. I have since put the rebuilt one back on.
I do not have a regulator in line. I tested the fuel pressure and it is about 4 psi.
I do not believe it is the float level flooding or fuel pressure problem because after trying to crank the motor, i can crack the banjo bolt to the fuel inlet on the carb and pressure will spray fuel every where. This tells me that the float is doing its job and closing the needle valve to prevent any fuel from getting in once full.
Instead of seeing a spray off fuel come out when i manipulate the throttle linkage, i will see fuel just leak down the center
Do I need to get some starting fluid and start it with that to get the Venturi effect going in the carb? to maybe get the carb to function for the first time?
I was going back through both carbs comparing things with them.
I did notice that the orifice tube that is under the main jet is very different between the two
The orifice tube on the left is in the rebuild carb. The one on the right is the parts carb. The one on the right has the bottom soldered shut, wheres the left side is open on the bottom
I am trying to figure out the float lever situation
The Rebuilt carb originally came with the longer rod to hold the float lever. It spans the top of the opening to hold the lever
The parts carb had a small rod that fit down into the bore
Which one should be there? And I was trying to make sure the float was level but when the directions tell you to tip the carb upside down and see if the float is level with the edge of the carb body, there is nothing holding the lever to keep it from coming out of the carb, so how do you get an adjustment if you cant get it to stay put without holding it?
And lastly, how much play is there supposed to be in the choke circuit lever? I pulled the choke circuit housing off the carb and there is no seal for the disc to body, so even though the disc will open to add fuel to the mixture, if it is loose would it be problem? The rebuilt cabr had about 1/16 play with the lever wiggling. The parts one had about 1/4 inch. There is a nut to tighten it down, should it be snug with no wobbling? If someone has a solex could the move their choke lever side to side to see if the lever has play? There is a spring between the brass disc inside and the housing.
So close to getting the thing starting. I know the WO is the preferred carb but i did not want to throw $$ into one until i could try to get this motor running a bit with what i have.
