my wonderful 305 only likes to start easily when its 80+ degrees out and if i get it running when its cooler out, it wont start back up worth of crap, this happened after i changed the carb to the holley, whats wrong here?

 

Are you running a functional choke system?

And did you replace the computer controlled distributor with a non computer controlled one when you ditched the original computer controlled QJet carb?

 

Agreed with Damon, one of those is almost definitly your issue.

 

the newest seen trouble with it is it has no spark, before it would run alright but now only fires on 2 cylinders I'd say and then dies, I'm so tired of the 305 lol

 

did you swap the holley on?

 

yea the Holley is on it now

 

When you say that it has no spark, do you mean that there is no spark at all or do you mean that it is only sending the spark to a couple cyls, as you described above?

As brought up, I'm assuming the Holley is not computer controlled. Are you running the stock computer controlled distributor still?

If you are, then this is your major area of problem. Replace it with an HEI style distributor with a vacuum advance.

 

thats exactly what i was gonna ask, you still got the stock dizzy on it or did you replace it with an hei dizzy?

 

it had spark to a few clyinders and now its just completely dead, there were pencil marks within the distributor cap so that led me to think its misfiring, and no the holley isnt computer controlled

 

and yea the rest is stock, all thats done to the motor is an intake and carb

 

swapping to a non computer controlled carb REQUIRES you to change out the distributor to a non computer controlled one as well. thats most likely the majority of youre problems right there.

 

As Travis said, you can't do one without the other. Although it might start, your not going to get very far without changing to an HEI. Like you said yourself, the car was running and now it seems to be running down a bunch of cylinders. Or think of it in a different perspective, you see misfire symptoms under the cap so you know that it's ignition related. Get a complete HEI dizzy from Summit or Jegs or where ever. It'll come with a cap rotor ect. Either way you want to look at it, replacing the distributor is your next step.

 

thanks guys! and ill be picking up a 350 to take care of all my 305 problems very soon. hopefully be doing this soon

 

a 350 wont solve the issue if you put the holley on without an hei dizzy....

 

i know this now lol
