Changed ignition coil, spark plug, ignition switch, and checked kill switch. Broke down and cleaned carburator a few months ago. Engine died while running which resulted in changing ignition parts because could not get a reading on ohm meter from end of spark plug cap and/or end of cable thru ignition coil. Now getting spark on plug when engine turns over with electric starter but engine will not start. Put one spoonfull of gasoline in engine where spark plug goes and replaced spark plug. Engine will still not fire. What else could i check?? Thanks for any info you can give me.

Welcome to the site, jszivos!
1. You mentioned that you rebuilt the carb. Have you checked for proper fuel flow afterwards? Is the plug wet after your crank it over a bit?
2. It also may just be something simple as installing a new sparkplug. I've found that sometimes after situations where you've cleaned a plug over and over again from dealing with running issues, the plug eventually gets to the point where it just doesn't seem to want to fire the engine off anymore and after a new plug is installed, it makes all the difference in the world.

It might pay to become friends with your carb again.
Here's a check list for your carb you might find helpful. The little greenish colored table on the left might just cover the starting problem you're talking about.

Also, if you go to the service tab, there's a "service movies" choice on the drop down menu. You'll find videos about the proper cleaning methods for Honda carbs.

It sounds like it's not getting sufficient fuel flow from what you describe. If it was getting proper fuel flow and still not starting, the sparkplug would be saturated with gas.
Take a look at the links provide by bw to get some ideas on what to look for and do on your particular engine and I'm sure you'll have it back up and running in no time.

A few Questions:
1. Does it have compress (check with gauge or finger)
2. Is the oil at the proper level or overfull?
3. Does gas blow out of the carb while turning the engine? (blowback)
Stuck or blocked valve is a possiblity.

Broke carb down, cleaned jets, bowl and float. Engine started right off. Let it run for a couple of minutes and stopped it. Tried to start immediately and it won't start. Removed spark plug after it would not start and smelled of gas but was not saturated or even wet. What other options can i try? Thanks

Normally if an engine has reasonabley good compression you put your finger over the spark plug hole and run the engine. Compression will try to blow your finger away from the hole.
If you suspect a stuck valve. Locate the cover for the valve springs (normallly a 2 x4 inch plate held with 2 screws) remove the plate. Observe the springs and see if they work freely or is one not working its stuck OPEN. If one is open then you need to remove the head and see what the problem is. Sometimes just a little oil and tap on valve and it comes lose. Somtetimes the valve seat is loose and it necessary to remove the valve and repair the seat.
