Warning to would be carb tuners.

Strato carbs are as fickle as a grouchy wife. If u are not very familiar with them, and had some one teach u a few things... Just don't mess with it.

That is why I am starting a thread on carb tuning. Any pros that want to weigh in give advice, or laugh at me and the other struggling tuners, welcome.

How so and what issues have you run into?

Had it running pretty good. Started trying to adjust the high screw to get it to four stroke. Made a 1/8 turn it stroked a lil so I give it another 1/16 turn out. Had to stop to help my 3yr old when I came back won't idle won't barely crank, returned adjustment still no go.

Maybe the carb is bad? Most carbs will work if you set the adjustment to the recommended position.

It's a ported saw. That's a no go.

It's not ported a lot but enough to make a big difference.

3rd attempt on my ported poulan was a success. Went back to basics. Re-gaped coil with a sheet of paper folded in half.
Pulled 3 times and removed plug to check if was wet with gas. Turned low serew back. Repeated this process till plug looked somewhat dry, only moist. Then another 1/16 of a turn. Started on 3rd pull after last adjustment. Only needed a lil fine tuning then, and idle ajusted. Running very good. Cutts like beaver teeth.

Did you happen to do any write-ups on this? My pp4218a started bogging on me after I tuned it, have spent a TON of time tuning the carb w/ my tachometer and can't get it to stay running well, the plug's good the filter's clear I've checked evvvvverything and can't figure it out -- would love to know more about "Re-gaped coil" as that's greek to me (do people tinker w/ the position of the ignition-module that's against the flywheel? On one of my saws a flywheel-fin snapped-off and knocked the module right off the block & banged-up the thing pretty bad, I used vices/clamps to get it looking good, did a ghetto-mounting (as the OEM screws that hold it to the block were sheared-off and stuck in the 2 mounting holes on the block), and it's run fine since!

My only comment is that I wish wives had adjustment screws on them.
