Wow, You have plenty of UNCOMMON things on top of this motor. So what intake do you have? looks like a standard q jet intake spread bore intake. I do not understand why they are calling your carb a square bore. square bore will have all the bores the same size. How do your gaskets fit on the spacer ...

They are calling this carb on summit site a SQUARE bore...BUT it is not it has front primaries smaller than the secondaries...THIS IS A spread bore carb. BUT that really is a moot point in the trouble your having...I am just trying to look up specs on the carb you are using. Jim

Did those drilled holes come factory in the carb?
If not
Why did they get drilled?

avs2 1906 carb is a square bore carb...YOUR picture is a spread bore carb....??? So what carb do you really have?
Jim

Well I have to say it has a lot to do with the holes in your throttle plates and or something is leaking air from somewhere? Do you have a car friend you can borrow a GOOD known running carb from? The distributor springs should not need the LIGHTEST spring just something below what you have there. M...

We can not have the website on for purchasing because there is just too many factors in buying rear end parts...WE tried but people would always buy parts they thought they needed and would want FREE shipping back for their blunder of not knowing what real rear is under the Muscle car. there were ma...

Throttle Return spring...YOU NEED 2... absolutely. If that one breaks YOU ARE SCREWED... lol Plus with 2 you will not need that hard of a return spring. Please for your safty and others on the road...They sell one inside of another type spring run a metal arm off the intake bolt or off the carb base...

Ok things I see. Carb primary throttle blades...open WAY too much in the picture for idle. Engine - vacuum line to valve cover...is it one way valve? also do you really need that? We just put open breathers - do you have emmision checks in your area? try to plug that vacuum line to valve cover for n...

What type of driving will you be doing with this car? like what is the cars purpose to make you happy...Example (burn outs, racing , road coarse, drag racing, ice cream getter? show hopper.... in state out of state trips...etc. ) we sell parts we use in all our builds. mostly Yukon and Nitro gear an...

Lets just get the distributor info then will get the car timed with out the vac advance to total timing set at 34-36 degrees Get it to idle at 700 - 1000 and take it for a drive. Hope you have a total advance timing light...IF YOU DO NOT...BUY ONE... if you are into cars this is a necessity . You wi...

Nic, Wow... sorry to hear your having a headache. Well we see what we can uncover here. First thing we noticed which is CRAZY most important thing in any motor is the distributor.... What are you running? You have absolutely no info on this item in your thread. Another thing is WHERE do you have you...

No .... mistakes... As long as your using good NEW parts you likely can not go wrong. Doubt you need all the extra stuff cover bars etc. On the street that rear will hold just fine. Stay away from rough uneven bumpy roads for burn outs and do not slide into curbs going around corners etc. You will b...

Jud, Good questions. Well in 1964 -1965 and all the way to 1966 Oldsmobile did not have its own rear differential. It shared the Buick or the Pontiac rear. 1964 and 1965 were the only 2 years the rears were narrow (54.25" f to f or 60" drum to drum total width) for the Buick and Pontiac re...

Crossing my fingers for you. Sounds good so far.

Not terrible...Could have been worse. Problem solved? Hopefully Yes...? Jim
