Car will start but after it warms up and runs you turn it off and will not start again until it cools off.
Do you
have the same problem?

Please explain the "start issue" in more detail.

Most interested in the "not starting" part.

Does it "crank" (turn over/ crankshaft rotates)?

If it does "crank",

It just does not "Start" (bust off!/ Run)?

If it does crank, is it "trying" to run? Spit, sputter or is it nothing but dry over and overs?

Or does the starter not do nothing at all? (Maybe a bad starter)

More to keep your end testing before you report back.

Do you know how to check for spark during the time it is acting up?

A really quick way to see if you have a fuel problem or an ignition problem when it is acting up.

Remove the breather top off of the carburetor.

Give it a one second burst (spray) of starter fluid (carburetor cleaner will work too! I have even used hair spray when nothing else was available!) Into the carburetor throat. Spray it into the area where the choke butterfly would close.

If you have a gas can, one teaspoon of fuel into the carburetor will work. (Giving a few options here!)

Quickly put the breather top back on (if it were to backfire, this would prevent a possible fire)

*** It is always a good idea to have a fire extinguisher handy!***

Now attempt a start!

What does it do?

Run for a moment? Or tries better than before (if yes, you have spark, some anyway, maybe a fuel problem)

No change? (Maybe no spark, may need to check for spark a different way)

Results thus far?
