'89 150 BlackMax idle/start problem...

[reyb]

I'm hoping someone can shed some light on the idle/start problem I'm having. The symptoms are:

1. Difficult to start. However, I can always get it started by increasing the throttle.

2. Once started it will rarely idle. After around 10 minutes of keeping the rpms up with the
throttle it idles fine.

Some things I've done so far:

1. Cleaned the carbs

2. Rebuilt the fuel pump

3. Changed fuel filters (external and the one on the motor)

Questions I have are:

1. Anyone know what years that the '89 150 BlackMax carbs are interchangeable with?

2. Anyone know how to test the idle stablilizer module?

3. Where's a good source to get a manual? I hear that the Seloc is not a good one.

Thanks,

Rey
