Hey! Looking to tune in my new to me Chrysler Outboard!
To get here see below and via a couple other posts:
Partially rebuilt carb along with many cleanings
Changed out fuel pump diaphragm
Changed fuel lines on motor and tank
Changed O rings on fuel fittings
Changed the starter gear-broke last week
Changed spark plugs
Changed Impeller
Reset the Idle screw so the line matched up with the roller
Bought a used repair book to help guide me
JerryJerry was a big help!
Chrysler outboard dude from youtube was a big help too!
So after all this I reset the carb out about one turn and the beast wanted to fire on pull 1! A couple more pulls and she did!
Could not keep it running without pumping the primer bulb every 30 seconds or so.
Made some minor adjustments on the carb and was able to keep it running. Made some more adjustments in Neutral and in Forward to the point where
it seems ok.
It idles in Neutral at about 2500 rpm and in forward at about 3000 rpm. I can drop this down but then I get to much vibration and inconsistency in performance.
Does this seem to fast of RPM?
Temperature on both cylinders outer walls seemed normal around 80-90 degrees and not to hot to the touch.
The motor seems to have strong acceleration and good reaction time. Just testing in a barrel for what that is worth.
Plan:
I am going to heat up all tank fuel lines to get a better seal at all the connections.
I will take out the plugs tomorrow and see how they look.
I think my fuel mixture has to much oil even though it's 50:1 A little to much smoke.
I will rerun it all again tomorrow to see if anything changed.
Any suggestions or guidance is always welcomed!
Thanks for reading
