Howdy all! I am new to this board becuase I just bought my first classic pony. A '65 fastback with a 289 and (reluctantly) a c-4 auto trans. I am far from a mechanic but really want to try and do most of the work myself. I hoping to abuse the talent on this board when I get stuck if possible.

My first issue is an engine one. The engines starts and runs great at idle, but when I first step on the gas it has a huge hesitation to the point of stalling if I don't back out. If I feather into it she runs great. After that first hesitation I can be in the floorboard all I want without a problem. Any thoughts?

Also, my wife wants to get me new wheels and tires for the car for a gift. Does anyone know if 17 x 8's will fit all the way around? What if I end up dropping it 1 inch with a new suspension.

Thanks ahead of time for any and all advice!

 

That hesitation of the engine only happens when she's cold am i right? my car does the same thing, it has to do with the choke on the carburetor. there is nothing wrong with this, but i suggest getting a carb with an electric choke. when the car "hesitates" when cold when u first step on it that is the cars way of saying "oh! you're ready to go?? well i wasnt" its no big deal at all and can be avoided by letting the car warm up more before leaving or like you said: by not flooring it first thing out of the garage. these cars have their own personality you will soon discover...you just have to get to know yours

 

Congrats on the new classic. 65 Fastback is a great car for anyone. Easy to get parts and loads of fun and style.

To your engine problem I'm not really sure. I'd guess it's either a carb or fuel issue.

As for the wheels you might have a clearance issue with 17". Might want to look at 16's for that year model. Someone that owns one of those year models will be able to answer it better.

Welcome to the boards and awesome car.

Post pics when you can.

 

if u want the tires at 17... because stock were all 14s and 15s....and show pics please ....and do whatever u want with the tires not trying to discorage you one bit and good luck

 

17" rims will work fine. You just need the correct backspacing. You'll need a low profile tire. I put '07 GT take offs on my car with 235/45/17 tires. They fit fine! For these wheels I had to use a 1.5" spacer.
From all the info. I found, you don't want to use a 16" rim because it can hit the tie rod end. The 17" clears it just fine.
Good luck!

 

I stand corrected.......17" rims clear the upper ball joint!

Here's the article I read on backspacing:

I have 17s on my 66, however, they are 17x8 in the rear and 17x7 in the front. I think they look cherry though.

 

i got 17s


if you do 17 it is mustang law you must fill them up

 

Agreed

 

I can't answer the wheel issue but, if you have a hesitation that bad either your timing is off or you have a weak accelerater pump in your carb. I can fire mine up and floor it out of the driveway without hesitation.

Forgot one...it could also be your choke not working like it's supposed to.
