Hyper 7 engine bogging-please help

[hachey]

hey everyone i have a month old hyper 7 that was running ok until one day the pull start got stuck so i took the engine apart and there was 2 "rocks" jamming the piston(could have been some other material) so i yook them out and everything else seemed ok but now when i drive it the engine bogs up as soon as i give it a bit of throttle, it will idle fine and cruise olang slowly but as soon as i open her up she just bogs up on me. any ideas?

If there was actually foriegn material in your engine while it was running, I wouldn't hold out much hope for it. I could be wrong though. How did "rocks" or whatever get inside your engine? They had to have come from the engine itself. Are they the piston skirts?

i have absolutely no idea but the "rocks" crumbled in my hand like dirt almost they were a sandy colour tho...
