Maintenance / Re: 302 Valve Adjustment
« on: November 17, 2008, 02:52:47 AM »
Here is a way to do it regardless of camshaft specs. I would never attempt to adjust a solid lifter camshaft with the engine running, but that's just me.

VALVE ADJUSTMENT:
1. ROTATE ENGINE UNTIL EXHAUST
ROCKER BEGINS TO OPEN EXHAUST VALVE.
SET INTAKE LASH TO THE DESIRED SPEC.
2. ROTATE ENGINE UNTIL INTAKE ROCKER
BEGINS TO RETURN FROM ITS FULL LIFT
POSITION. SET EXHAUST LASH TO SPEC.
3. REPEAT FOR THE REMAINING SEVEN
CYLINDERS FOLLOWING THE 18436572
FIRING ORDER.

Hello. What were the cylinder head casting numbers for a 295 horse 350? Did they come with bolt holes in front?

Thanks

Steve, a wire wheel is not good for cleaning plugs. The base of the center porcelain cannot be reached with a wire wheel, the plugs will continue to short out (fouled plug). The plug sand blaster does a much better job since it can get down to the base of the center electrode  porcelain. If you do get one and clean your plugs with it make sure to use carb cleaner and compressed air and ensure that you get any sand out of the plug after the cleaning.

It is possible that some varnish may have plugged some of the air bleed circuits. Before you tear into the carb again first check the float levels as suggested. If the levels are okay, check to see if there is fuel dribbling out of the venturis with the engine off and on, remember to use a mirror if the engine is running. You don't want a backfire while looking down the carb., please use a mirror. If all this looks okay we'll move on to the next step.

I'll try to help Steve. Always start with the basics. I assume the timing is okay. Does the engine get to operating temperature? I would remove the sight plugs on the float bowls and turn on the fuel pump (engine off), check the bowl level. Also with the engine off and fuel pump on check to see if there is any fuel dribbling out of the venturi boosters in the carb., if there is the float level is either too high or there is something in the needle and seat in the float bowl that is not allowing the float to shut off the fuel and it is flooding out. It sounds like you are getting a good vacuum signal to your carb if you are seeing changes in the idle mixture screw adjustment. Just a thought but is the choke plate completely open on the carb? With the engine on use a mirror to look down into the carb and see if there is fuel dribbling out of the venturi boosters at idle, there should not be. They do sell a mini sandblaster just for plug cleaning, some part stores carry them.

Maintenance / Mono/Multi Leafsprings?
« on: November 15, 2008, 07:28:38 PM »
Hello i'm a newbie here. I was wondering why some Camaros came with mono leaf springs and some with multi. I was thinking it had to do with h.p. ratings and such but I have seen 12 bolt rears with mono leafs so that can't be it.

Thanks
