A neighbor asked me to help. So far he had someone else rebuild the carb,change plugs,wires,points,condensor.

I pulled the plugs-there is blue white spark
The carb was flooding so I pulled it and took it back apart to check float level. I really have my doubts if there was a rebuild. The main needle under the float looked new, and that's about all..I found the gasket between the bowl and the top to be totally saturated with gas.

I fooled with the timing to no avail,squirted starter fluid into the carb and then into #1 sparkplug hole. nothing.

The plugs are dry still.
I suspect carb.

what do you suspect?

On a happier note, I bought an 8N from a fellow this morning for $400..it won't start, it's rusty, but it's complete. right down to the almost perfect grill. :)

Instead of WD40 in the cylinders, try Marvel Mystery Oil. It does sound like sticking valves. Have you gotten the #1 piston to top dead center and then checked that the rotor is pointing to #1 wire. If it has the fiber gear on the cam, it could have jumped time.

doesn't look good. Put a carb from a working 8N on-no go..
last and should have been first..a compression check..1st dry, then i used wd40 for the wet test.
dry first_then wet
#4: 75 then 50 (?) #3: 70 then 55 (?) #2: 35 (!) then 35..#1: 50 then 45

told him to spray wd40 through the spark plug holes for a week or so, cranking it when he does.

He was confused as to why it ran so well and just stopped...

ME TOO.

told him he was lucky he got as much bushogged as he did.....and...then

told him if he got tired of fooling with it. I had an old folks home for 8N's just over the hill.

Scott, You got a higher reading dry than wet? Try the compression test with motor oil not WD40. Check the valves, they could be sticking.
How was his oil pressure?

I had a simular problem and it was suggested to me to check the fuel flow. Disconnect the fuel line at the carb and open the shut-off valve. You should have a good flow of gas. If not start checking filters. If my memory serves me correct, one in the tank, one in the fuel bowl and one on the carb itself. The one in the carb won't show up as bad by removing the fuel line. You'll just have to look at it or take it out. Good luck.
