Hey fellas,
Motor is a 1995 Evinrude 130 hp looper, E130TXAOR.
Got her after she was setting for 5-6 years. I replaced the VRO diaphrams, changed the fuel lines, fuel filters, rebuilt the carburetors and put in new waterpump & thermostats.
Compression in the motor is 135psi in all 4 cylinders. Did a decarb with seafoam and cleaned the piston heads up nicely (from what I can see into the spark plug holes. Spark is strong on all 4 cylinders, and DVA voltage is correct off all 4 ignition coils. Disconnected VRO due to faulty alarm. Running pre-mix. Spark plugs look good.
The motor idles great in neutral at about 1000rpms. Put her in gear and the idle speed is at 700-750 rpms and she will just cut off after a few seconds. If I give it more gas and keep the idle speed at 900rpms I have no trouble. Boat gets right on plane, and cruise and WOT is excellent. Doesn't gimme a lick of trouble in those areas.
Every once in a while she will take 3-4 starts to get her to fire, even if motor is still warm. Will sometimes lose pressure in primer bulb. Have to advance the throttle quite a bit to get her to fire. Also, when I take er out of gear and put er in neutral, the idle speed will stay up at 1200-1400rpms for about 10 seconds, then will drop back down into the 900-1000 range. Also, sometimes it will surge a few times until it settles back in at a neutral idle. I tried to back out the idle air mixture screws from the recommended 2 1/4 turns out, to a full 3 turns out.
Maybe I have an air leak at one of the fuel fittings? Cant see any gas dripping anywhere. Possible that I didn't clean the carbs well enough? I used a carb cleaning solution and blew them clean with compressed air................
