Looking for some advice on what might be wrong with my motor. I have done a search on this site and have seen some others post the same problem but I haven't seen the solution. The motor is a 1988 Mercury 150 2.0L carburated engine. Here's my problem. First let me say this motor starts and idles great. The problem occurs whenever I let my motor idle for long periods of time (warming up, idling through no wake zones, etc.). When I try to get the motor on plane, it loads up as if its flooded. I have tried to push in the choke while this is happening and it doesn't help. I have also tried to pump the bulb and it is firm. I can shut the motor off for about 2 minutes, restart it and she will get right on plane. The other way to get it on plane is to put it in neutral and rev the engine to about 3-4 rpms for a few seconds and then put it in gear. I have taken it to two different mechanics. The first one changed the stator and switch box. That didn't cure the problem so I took it to another mechanic and he replaced the check valves. I have tried to make sure my motor is level when idling (heard that may work) but that really hasn't helped. I would appreciate any advice or maybe point me to a really good mechanic in eastern North Carolina. Thanks.
