73 - 65hp Johnson dies from idle to run....

[guz101]

I've replaced all of the gas hoses and plugs. 50:1 oil with seafoam. Motor sat in woods for 3 to 4 years before I got it. Motor will idle with start handle up when going from there to run motor bogs and stops. 4/5 times before it will take off.

Are you running this on a built in tank or portable?

If it sat that long a Carb overhaul is good preventative maintance to protect from running lean through the high speed jets and burning up the pistons. That being said... often times problems with transitioning from idle to high speed involve syncronization between the carbs and the ignition advance.... See manual for sync instructions.<br /><br />Good luck,<br />Mike
