|
|
I'm having issues with this engine since break in. It has about 3/4 of a gallon of 20%. Seems to flame out and I chase the tune waaay too much. Temps never above 270 degrees. I know they are sometimes finicky but I have 7yrs in the hobby and have run my fair share of mills.
Anyway i opened her up and found this? Looks like it's a defect at the braze line (for lack of better word). it's located right behind the bearing and you can see wear at that location on the crank
What do you guys think?

Do you have pictures of the crank?
How open was the Idle air gap( at the carb)? |

Added crank pics. idle air gap was about 1mm. She fires right up and idles and runs well until it gets to temp about 220 to 250 degrees. At that point it will intermittently die (flame out?).
It looks like a defect in the cast to me. It's pretty obvious right? OFNA email page is not working so I need to call them I guess |
