I have an 1980 85HP Chrysler OB with electronic ignition. I have been struggling to get it to run consistantly. Here is what happen on my last test run:
1. Started fine, idled good.
2. Brought up to full throttle and after a small caugh, came on strong.
3. Ran full throttle for about 1.5 minutes and engine throttled down by itself, as if I had moved the throttle back.
4. I brought the throttle back and it stalled.
5. Waited about 2 minutes, started up fine, idled good.
6. Brought up to full throttle, ran good for about 2 minutes.
7. I slowed to a stop, idled good
8. Brought to cruse speed (3/4 throttle) and ran good for about 2 minutes.
9. back to idle for a while - seemed fine, but then overtemp alarm sounded.
10. Brought up to cruize, temp alarm went off ran good.
11. Up to full throttle again and it died again after 2 minutes - just like #3
Sorry to be long winded. Here's what I have replaced:
Water pump and thermostat
Spark Plugs
Wires and Cap
Coil
Removed, cleaned and replaced all 3 carbs
Any suggestions would be greatly appreciated. Any mechanics in Holyoke, MA area, let me know, I'm about out of ideas and would be willing to pay if someone thinks they can fix.
