Were any of the spark plugs smashed when you took them out?

no. and it was running great up til this morning. plus the cyl3 miss is gone. now its missing across the board. i think its gotta be the pump at this point. i had to take the pump assembly apart and clean it to get it running when i bought it. i took the screen off the pump itself cause it was clogged, and because there is one on the bottom of the assembly. i think im just gonna break down and buy a pump. i figured i would need to do it eventually anyway. i wad just hoping maybe there was a common problem i didnt know about.
