Q:  I have an old 1977 10 h.p. Murry 42" rider with the 3 blades. As you might imagine, it's always a thrill either replacing this pulley or that bearing, etc.

Lately the one thing that normally works all the time (the B&S engine) kills out after a short time of driving. I have taken the gas tank off and noticed the screen was rotted @ the bottom, cleaned it and put a in-line filter along with new gas line. I removed the bottom cup and cleaned the needle, too.

It almost seems like it's starved for gas when it starts to go out, because when I push the choke in it goes for a little while longer. I also have to jump start it even though I have a new battery, when it acts up. When it's cold, it starts right up. I also seem to be able to keep it running just fine in the garage...big help!

I wondered if somthing like a piece of that screen got lodged in the carb., but it seems to be real smooth when it does run. What do you think?

A: I would think that the condenser has gone bad and when it gets hot it fails. That is usually what happens. Next time it quits check and see if you have any spark at the plug. If not then the condenser is a good possability.
