Running engines produce plenty of heat. I'd next consider a clogged air filter, particularly if there a lot of dust.
De,
It was running . . . then it got harder and harder
to keep running. I was having to hold the choke in
to keep it running. Got worse . . would not stay running.
I did change the air filter and the spark plug . . no help.
I think Mr. Monk is right . . . starving for fuel.
Zim.
