3.5 4 stroke
used to start easy on first pull. I would pull out the choke, start it, then after a few seconds, push in the choke.
It now is very hard to start. Requires full choke, then many pulls. Once it starts, I have to let it idle with at least half choke for a long time; up to several minutes. If I push the choke in before this, it dies.
Once it gets warmed up, it runs normally and has no problem at any RPM
. Tried a new spark plug
already. The outboard
has no (replaceable) fuel
or oil filter
Any idea what I should try next?
