Husky 50 smoking where is shouldn't

[spudulike]

Thanks Spud

 

I got some 280 grit w/d and have been rubbing the bore and it has made some improvement - see photos. But above the exhaust port the grooves are deeper especially on both edges of the exhaust port.

 

After a lot of rubbing there was no improvement in these grooves and I don't see them coming out. Don't know how well the photos will show this.

 

The bore has some scoring but can't tell how bad, I have had some bad looking bores still make good copression and work fine for a year+

 

Don't keep rubbing to get rid of the score, you will produce slight cavities in the cylinder wall that will lower compression and cause blowby of exhaust gasses:thumbdown:
