UPDATE PART 3

okay i did the fuel fliter and added some isop. alc. just in case water was the cuase and everything is running fine as of the last 12 hours. I have found that it idels at 1000 when first started and as it warms up and raises in temp the idle drops down to around 700 give or take. Is this what it is supposed to do? RED
