1987, Sunbird, Eurosport, 18ft, 165 hp, 3.7L, 224CI, Merc, Alpha One I/O, Straight 4<br /><br />I just purhased the boat, I was able to get the engine running before I purchased the boat.<br /><br />I brought the boat home and ran the motor again with no problem.<br /><br />Then I power washed the interior and performed a simple tune-up, now the motor will not run. I replaced the plug wires, plug (.035" gap), points (.022 gap, dwell 30), condenser. The boat will turn over and cough a little, make a little smoke and run for two seconds when I let off the starter. It almost seems like it wants to run when the starter is running, the exhaust is coming out, but i never can get the engine to run. The throttle lock out does not work so I can not start the motor with any throttle. I checked the spark and I have alot of spark, and the timing is around 8 degree TDC, (running on the starter). The plugs were a little wet from trying to start meaning I have gas in the motor, replaced the plugs and still no start. <br /><br />Spark, Gas, Air (removed air filter), Timing, Points OK, what else is there in the boat to make it run. <br /><br />Thanks in Advance,<br />Shawn <br /><br />Note: Compression is as follows,<br />Cylinder 1: 150<br />Cylinder 2: 155<br />Cylinder 3: 132<br />Cylinder 4: 128<br />I figured the compression is within 15%, I figured it was ok.
