6hp fisherman idle issue!!

[Evinrudej]

Just got an evinrude 6hp 1970 starts up fine wishing three pulls cold and once when it’s warm has good compression. I had the idle set fine using the steps mentioned in these forums. When storing the engine I accidentally moved the knob out of place and when going to reset it whenever I make the mixture completely learn or rich the idle does not seem to be effected. It will idle low for about 5 seconds then die. Not sure what’s going on carb has been rebuild as well as point and coils

Also forgot to metion that it used to idle fine at the shift position on the lever now anything just below start will kill it

what did you do to "clean" the carb ? did you inspect and clear the top drip chamber and the very small orifice feeding the top half of the carb via the side fuel channel ?


see carb issues on older carbs yours has no bowl but basic issues remain

Does spark jump a gap of 1/4" or more on both leads ?-----The motor should respond to low speed mixture , so revisit carburetor work.-----Check the pointy end of low speed mixture screw.---Post a picture of it.

This is the diagram for my carb thinking I should just do a rebuild myself since the guy before me may have used cheap parts it looks like

do the easy stuff first

Racerone's post#4 is critical ...to progress you need to answer all questions

have you tried pumping the fuel bulb in case the engine is starving

Rebuilding these carbs may only entail a good cleaning of all passages and blow dry them. did you check the small side channel orifice feeding the top section ?

the air may be leaking by the LS needle temporarily grease (butter) up
the shaft to seal it 100 % (see causes in the above picture)

is the tank vent open ?... remove the cap

I also have a 6 H.P. Evinrude that I had a problem with idling & starting after I rebuilt the carb with new, CHEAP parts. I rebuilt the carb a second time with OEM parts and it was a world of difference. The cheap parts that I put it were junk. The gaskets literally softened and became distorted from the fuel in the carb bowl. Replaced the cheap parts and I was all set. Runs great still after over a year ago.
