Try a little starting fluid. If it starts or sounds like it is trying to then you most likely have a fuel delivery problem.
Could be that your carbs are needing a thorough clean up. Could be clogged jets, stuck float valves, etc....

Don't over think it..
Air
Fuel
Spark
... get a good / full charge on the battery... shoot a little starter fluid (or any fuel you wish) into the carbs.. choke it..you say you have spark.. and I'm pretty sure you have "Air"...
go from there...
I remember at sometime I either heard or read "90 percent of your electrical problems are carberator related"...

yes choke is on. The starter spins fast and I actually got some engine start and an exhaust note a couple of times(yes fuel is on). I will try starter fluid next.

Really there are only 3 reasons why an engine (any internal combustion engine at that) won't start

1. Mechanical interference/issues (no compression, seized, etc...)
2. No fuel (carburetion issues)
3. No spark (could be bad or weak battery, bad ignition coils, bad spark plugs, bad ignition timing, etc...)


Try to keep things simple and eliminate one issue at a time.

I occasionally get scolded on another forum for using starting spray/fluid to start a motorcycle engine.
Sometimes they need a little help to make that first surge. I may be too quick to spray but I think it is
better than running the battery down and overheating the starter. I have been told many times
"that stuff will ruin your motor". Hasn't happened yet.

4 cycle engine is, suck, squeeze, bang, blow in that order.

So it restarted when all warmed up with just one push. I will try a cold start see what happens. Is seafoan worth putting in?

Yes Seafoam does help to clean up the carbs a lot.

Yes, ... although there is a lot of "snake oils" out there.. but some additives are benificial..
Especially with the new fuels.. even with non-ethenhol or "ethenhol free".. I still use an additive..
staybil, Lucas, seafoam...

The 79 Hondamatic starts first press, don't think it's cold weather related. I did take starter clutch out and bolts were loose! thanks for all the help though
