I have an early 90's (possibly late 80's) 20HP Evinrude on my pontoon (Model # J20CRLEIE) that will start fine, but won't idle. You can keep it running by using the secondary throttle, but it does not run at FULL RPM's that way either with the lever all the way up. It will run fine in reverse, but while going forward it won't run until at least 1/2 throttle and runs well at 3/4 throttle...misses and doesn't sound right at full throttle.

You guys/gals have been helpful before, any ideas or suggestions?

Thanks and Tight Lines.

check plugs and compression,,if your using a primer bulb hose,check for any leaks of air or fuel,,,sounds like a dirty carb problem tho
