OK, it's a Poulan 4018, but that shouldn't matter. ZAMA carb.
The situation is this. Carb assembled correctly. Saw runs great after I installed a new cylinder and piston (I know, Poulan, but it was a hobby project and the saw was free to me). Saw idles well and revs well. Metering lever set properly. H and L screw adjusted between 1 to 1-1/2 turns out.
Typical cold start up procedure is leave it at "run" and pull about 5-7 times till it pops, then set it at "high idle" and pull a few more times till it starts. If I try to start it from cold with the choke, it immediately floods out. I mean "pull the plug and pour the gas out of the cylinder" kind of flooded.
Warm start-up is "high idle" setting and one pull OR two pulls on "run" setting - all normal.
Again, it runs GREAT after I get it started.
This is not really a HUGE problem, but with my other saws being "normal", I'll never remember the starting procedure for this one - I'll put the choke on and flood it out. Besides, mysteries regarding chain saws annoy the HELL out of me till I figure them out.
I would suspect the normal flooding carb problems if the saw didn't RUN so well after the funky start-up procedure.
What's wrong here?
