painting... the engine has plenty of go its just that I get to around
65 and I hear alot of noise coming from under me... like winding from
the tranny cause it just sounds like cycle of winding and it wont go
faster like I drove it up to my house from the city up a big hill and
I wasnt pressing on the gas to keep it at 65 it was just cruising
along... exhaust sounds nice and deep this is our 4th mustang but the
first with these problems... I have a backfire but its cause of an
exhaust leak which will get fixed next week. im going to pick up a
service manual when I go and get the new vac mod and a couple of
gallons of fresh antifreeze cause im going to clean out that first.
ill get a vacuum gauge too... the carb was readjusted and just
rebuilt cause I was told that maybe that was my problem. my car
doesnt have points it got the points eliminator kit from accel and a
brand new distributor cap. idk if mechanically inclined enough to do
work with the timing chain tho... but thanks alot guys this the best
suggestions I have gotten from anywhere.
