Motor cutting out and coming back on at 4500 rpm after changing timing belt never did it before it act like its either gas cutting out or timing messing up. It will run all day at 4000 rpms but you try to go any higher she starts to cut out.
Checked filter poured it into a clear container had some stuff in but not alot going to check the little filter in the carb and take the carb of and clean it out to and check my jets and buy a new filter to.
