Re: HELP CARB PROBLEMS
You can try the old trick of starting the engine and pinching off the fuel line while you tap the body of the carb.
Are you sure it's flooding?

Re: HELP CARB PROBLEMS
So i had this same problem with my q-jet. It turns out my choke was getting stuck, have you checked that? it could just be your choke thermostat. I know a guy here who has rebuilt carbs for like 20 or 30 years and he helped me find this out. also, after you think its flooded, try taking out one of your spark plugs and see if any gas comes out. mine was so bad that was happening, so i took all my plugs out, cleaned them, and let them sit for a few hours to dry out. i put them back in and tried starting it without giving it gas and it started up, but everytime i pushed the gas the choke came on and flooded me out. i ended up wiring my choke down for a while and it was hard to start cold but it did eventually start. choke thermostats arent too hard to replace, so i would check that out before going into a whole rebuild.

Re: HELP CARB PROBLEMS
There is no tensioner. What's your skill level with the SBC? It gets a bit involved changing the timing chain. You'll have to elevate the engine to loosen the oil pan. I use the Fel-Pro one piece oil pan gasket, they're great. If you have the means, I would replace the cam as well. If you remove the distro cap does the rotor turn when the engine is turned over?

Re: HELP CARB PROBLEMS
You can't take the timing cover off without lowering the oil pan.
If the rotor spins, then it's not a problem with the timing chain.

Re: HELP CARB PROBLEMS
Brian, what I have always done was this..... Once you get the timing chain cover off ( however you do it is up to you) pull the old timing gear set, rotate the engine until number 1 piston is at top dead center if that is what the motor calls for. I use a sparkplug that i modified to accept a dial indicator so i can get it perfect, but a screwdriver will work..just dont get it jammed. align the marks. install the distributor with the rotor pointing toward the cylinder you put at top dead center, tighten it all down, reinstall all the covers. Off ya go.

Re: HELP CARB PROBLEMS
The Zoom timing set is fine, better even. It will be a slight bit noisier, as the nylon gears on the original set are for noise reduction.

Re: HELP CARB PROBLEMS
When the timing marks on the sprockets are lined up dot-to-dot, the engine has both #1 and #6 at TDC. #6 will be firing.

Re: HELP CARB PROBLEMS
#1 is the one that will be firing
Here is distributor removal directly from Haynes manual:
Installation if the crankshaft was turned after distributor removal
17 remove the number 1 spark plug
18 place your finger over the spark plug hole while turning the crankshaft with a wrench on the pulley bolt at the front of the engine
19 when you fell comrpession, continue turning the crankshaft slowly until the timing mark on the crankshaft pulley is aligned with the 0 on the eninge timing indicator
20 position the rotor to point between the number 1 ad 8 spark plug terminals in the distro cap on v8's, between the 1 and 6 terminals on the v6 engine, or between the 1 and 3 on l4 engines
21 complete the installation by referring to steps 10 through 16

Re: HELP CARB PROBLEMS
Yes, make sure that the timing for the camshaft is right, no need to destroy valves for lack of reading the manual. I checked my Chilton's and it says the same thing almost verbatim. If you point it at the #6 spark plug terminal then you'll be 180* out, if it starts it'll run really rough. Firing order is 1-8-4-3-6-5-7-2, rotating clockwise...I think.
This is the way that I did mine since I already had the valve cover's off. Look at the valves and make sure you know which valve is which (ie, intake vs exhaust) on the #1 cylinder. Rotate the motor while watching the valves, and open and close the exhaust valve and then before the exhaust fully closes the intake will start to open. Continue until you close the intake and then start watching the timing tab and set the timing mark to zero. Stick your screwdriver in the plug hole and rotate the motor back and forth to make sure that the timing tab is correct since you took everything apart.

Re: HELP CARB PROBLEMS
I little basic mechanics here. If you take the firing order of a motor and split it in half you will find your companion cylinders. Companion cylinders pistons are in the exact same position but opposite valve position. So chevy firing order. 18436572
1843
6572
That makes 1-6,8-5,4-7, and 3-2 all companion cylinders.

No, that shows what cylinder should be firing when a it's lined up for the other cylinder to fire when it's 180 degrees off.

Re: HELP CARB PROBLEMS
Heres where im at timing chain went in sweat and i know that the timing is good it fires right up with just a touch of the key but to me the valves seam a little noisey sould i do a valve lash job on it because when i did valve lash last it was with old chain and let me tell u that cam gear was stripped and i looked like the vinal coating had been missing for a long time like i said it is running like a top now it may just be the new timing chain u guys said it may be a little noiser but to me it seams like the valves are slapping just a little any advice would be greatly aprecited
Re: HELP CARB PROBLEMS
I have never seen a motor run 180º out and i have made this mistake as well as seen it made by others. Usually if anything it backfires through the carb and thats only when you start twisting it around and retarding it enough so it is firing with the intake valve open.

Re: HELP CARB PROBLEMS
Brian you might as well tear down the motor and do some overhaul, believe me it will save you a lot more time than separately doing all the same things, you know might as well get um all done at once, it will also give you good opportunity to give her a throw check up

But, sounds like you need to at least check the rockers.
