Yeah had that same feeling on my 1st ever port job - was test cutting and had it bar deep in a huge log and the saw just stopped dead mid cut?? Went to thinking the worst and it was just slap out of fuel. hahaha Still the worst feeling....
Only a troll who’s never ground on a cylinder would call your work crappy. I haven’t had this happen to me yet and I’m glad everything else seems to be fine with the saw!
Smooth creates a drag on the flow where the right roughness creates an 'air cushion' and, in some cases, it'll increase the flow by smoothing the flow characteristics.
From what i gathered the only thing that consistenly flowed more than a bur finish was 60 grit. Golf ball and polish flowed less. The only spots golf ball helped were the insides of a sharp turn. I still polish exhausts but that is to reduce chances of carbon build up.
@Super-Dave-Outdoors in theory, a dish shaped piston with dimples should create a pocket of suspended molecules (charge)... I have an 888 out in Tennessee with a domed/dished piston... I should've dimpled that piston. I'm not a fan of dimples on the squish or in the ports. It's too much work for little if any gain. What I do like is a small/narrow flat squish band followed by a taper towards the chamber with symmetric grooves pointing towards the center of the chamber... approximately .020" deep grooves. The piston work is basic, with an outer flat landing and a dome with dimples.... Oddly enough, I didn't notice much... if any differences in performance, but i did notice a tone difference in the saw... I have yet to open up that saw and/or do Real tests.

The clatter was what had me fearing the worst. Havent ever clean sheared a key before so that was new to me.

Nobody has been talking bad about my work. I just want the current project to be better than the last so i try to be self critical.

Ive sheared a key too. Nice lookin port work Dave. 👍
It scared the crap outta me
Phew😨 tho nothing like how you felt, my heart sunk at that moment as well!
Yep, glad it was the flywheel and not the engine. It was a pretty ugly noise.
Tried leaving a comment several times but YT want allow it👊AP
