I was running my A15 for 1hour and 30min the other day and for the most part it runs great! As I was running it it has a big problem! It it almost stalls and random times! In that hour and a half it tried to stall on me 5 times. I don't get it?!?!

Any ideas?

Most common cause: Fuel filter pluged or loose fuel line causing air to draw into pump. Possibly crud in the fuel.

2nd most common: Contact Points set in the distributor is no adjusted correctly. Replace every 12 months/12,000 miles. Dunno how many hours that relates to in a stationary engine.

when your engine stall, try to touch your ignition coil. it shouldn't be hot. if it is hot or very warm, replace it.

i had the exact same problem a few years ago and it turned out to be bad wiring to my battery GND terminals (or 12V) cant remember. Either way it confused me a lot until i actually traced it all from the battery to its relative places and found some crap wiring. Upon repairing, the beast was perfect again.

edit: with my problem, obviously, the entire 12v rail would be gone. everything would cut out, incl the engine.. lights, dash lights everything..

edit: yeh everything would cut out ; everything! if your motor is still idling then goes back to normal rev's (when you hit the throttle) then like other members said its likely a fuel delivery problem. goodluck!

I changed the filter. As for the fuel line, I will have a look:)

I don't think the contect points can be adjusted. It's electric. I could totally be wrong because I don't really know what I'm doing!

I will do that:) Thanks!

Could that cause this problem? It never totally dies out. It just sputters then goes right back up to the rpm's I set it at.

I will follow wiring to see if that will do the trick. The wiring around the battery looks bad. When you say everything would cut out do you mean it would totally die? My motor keeps going like it going to stall but then it goes right back to normal. I don't need to restart. Let me know please:)

There are many things that can cause your symptoms. But it is less likely to be electrical (or it would be more erratic), and more likely to be fuel related.

Did it start occuring about the time you replaced the fuel filter?Or what else changed around that time it first started happening?

could be the anti dieseling solenoid in the side of carb as shown in picture. i had an issue with it wanting to stall randomly and traced it down to that.

You can easily test that theory. By disconnect the idle-cut solenoid internally. See anti-diesel valve.
