okay here is the deal i bought good housings from willow at lucky 7 they just need to be cleaned. He said i have to clean the inside of the housing and use some sandpaper because it has minor minor groove. So my question is what sand paper grit do i use to sand down the inside of the housing so the groove is removed all while still keeping the housings healthy. Another question is how do i polish the inside of the housings. here are pictures thanks - Gabriel

 

2nd to last picture the rotor housing on the right is bad. I wouldn't reuse those housing because the "crome flaking" doesn't look so healthy. I have one that is a little better then that, but I wouldn't it.

 

why doesn't it work
they told me it was on a running engine
that they were perfectly fine

 

thats not chrome i just cleaned the engine with carb cleaner

 

got the answers to my questions
delete this bulletin pelase thnx

 

oh and just to let some people know
willow only advised me use fine sand paper because i am on a budget, he offered to sell me better housings but i was short money so they do legit work he just advised me on a little trick since i am low on $$
