There’s a lot to tell, yeh it passed a p&v test, although when turned the pto side up it died. I checked the p&v again passed again.
I checked the carb, I thought it was a 194 but it’s a 394, (wt) I lifted the metering leaver a tad, as it looked like it needed it.
The carb L 1 turn H 3/4 turn
As it says on the side, I didn’t have my taco
It was not really 4stroking I did 5 screaming cuts with a 16” an new 325 chain and buried deep.. then it started to smoke, like it was hot, very hot.
The saw is only lightly ported and no muff mod timing is adv 20thou off key.
In reality, it was slightly lean, I got home and looked up the plug colour. I thought it was the elecrode but I should have been looking at the rim,
it is no colour/gray-white
It could have been worse thou, next time will be different. I will taco‘ it and not scream it..
I’ve got the cylinder almost cleaned up.. And I did get another pistonlast time,, just in case !.
And the oil was 50:1 green stuff from Stihl, that some one said was better than the red Stihl stuff.
It’s now been made up to 40:1. Which I should have done in the first place.
I will see if I can up the vid. It will make you giggle
