1985 90 mercury Idle problem

[rjsizemore]

I have a 90 mercury on a 15.8 ft fiberglass boat. Just had a stator an trigger replaced also power packs. When starting have to choke it with the throttle down Will not Idle at all. Sometimes it will idle for a few seconds but when you put into gear it quites. Its also very slow to plan has good compresion on all 6 cylinders rangeing 125 to 130 looking for some advice

If they determined that the stator and triggers were the cause of your problems, and it didn't fix it I would demand that you get your money back...<br />I assume that they did the sync and timing also?

Sounds like you have a lack of an active vent on your gas tank. Try running on a portable tank.<br />Also tank side check valve in bulb maybe causing<br />problem. <br />

well I cleaned my carbs again it will sit and idle with the muffs on but will not start unless you have the throttle down. I let it idle for 2 or 3 minutes and still would not start unless the throttle was down.
