I did go thru everything that I removed.
What if I didn't take out the paper and it went farther than the manifold,like say into the valves?
Would the tissue dissolve eventually?
Would it prevent it from starting?
Do I need to take the heads off?
REBUILD the engine?
Come on man!!! I'm desperate!!!!
I would love to be able to drive my toy on the hot sunny days!!

I once had a 1200cc that literaly ran on two pistons.

If you have the time , take the spark plugs out and see if you can stick a small wire and snag any trace of the tissue.


Take a good look inside the distributor cap at the contacts for the rotor.

Get a voltimeter and check each cable (coil, spark plug cables etc.)

I had a similar problem as well.. I changed out the coil and the coil wire and nothing ??? I then swapped out my pionts and it fired right up. The problem was the tab on the points that make contact with the dizzy shaft was broken off and there was no gap. I would try swapping a new set of points into it... DONT FORGET to grease the leading edge of the contact tab...

Don't sweat the paper towel, the very worse thing it could do is get caught under a valve and it would be obvious when that cylinder lost compression. It'll go right through and get chewed up and spit out.

Have you tried a dwell meter on the points? Did you have the carb upside down or on it's side while it was off?

Thanks for all the advise.
First off, I have electronic ignition, so no points to deal with and all the wiring is still intacked.I checked the power to the coil and have it.So now I am, going to try a new coil wire or maybe a whole new set of leads.
I'm not positive about the tissue,I just don't remember.

exactly!!! that's why i was asking about checking power to the + & - side of the coil.

x2.

easiest way to find out is to swap in a set of points & a condenser.

OK so if you hold a spark plug cable at the plug end and have someone fired it up... you would know if the electronic ignition is working or not... ;D

...found that the coil wasn't giving a spark.

the spark wont make it to the plug if it's not even making it from the coil!!

At last, SUCCESS, after dicking around for a week on everything under the hood(rear end of car).I finally found the problem to my heartache, it seems as though the electronic ignition sensor worked itself away(vibration maybe?) from the rotor. I noticed that it seemed to be quite a gap,so I put it a little closer and "boom" it fired up.
Hopefully, tomorrow I will be able to see if all this was for not.
All I wanted to do was make a little more room for my throttle to open up and what happens, all hell brakes lose!
I wouldn't have thought it was possible to have somthing go so wrong so fast.
I want thank everyone for all the advise and possible solutions.
By the way does anyone know what the gap is on the electronic ignition?

By the way does anyone know what the gap is on the electronic ignition?

IIRC, the gap is .75mm.  However, I believe the hole in the electronic module's bracket is countersunk, so it is not adjustable.  Is yours a slotted hole?

well, after getting it going,I drove around a bit and it kept stalling out.I would adjust the carb a bit and it would start up again,then stall a little later.After finally getting back home, I checked the timing and rpm with my meters and set everything right.Then the battery frickin' died but I think I need a new battery doesn't seem to hold a charge maybe I'll get a six pack, they are suppose  to be good.
I also noticed that the rubber boot that connects the manifolds had a hole and gas was dripping out on to the tin.
Could this have much of an effect on the way it runs?

I think so....it is an opening which will allow fuel to leak out and air to leak in ;D

While you are at it... check the gas tank line out (under the tank.) It may have a small cone shape filter which (when plugged) may limit the fuel being fed on your fuelline to the pump. When it blocks the foel you can ussualy stat and go ...then it will stall again. You will start checking on things and when you try again it will stat and do the same thing again.

Finally got it running!!!!
I hope to do alot of driving this year.
It hasn't run so good!
I think cutting out the alt. body was a good thing.It seems to run alot better than ever.I am very happy.
If you see me out driving give me a honk,  maybe exchange a few words.
My plate is " 74 BUGY"
Have a good weekend!!!
