Sup y'all....
So I've been asked to tinker around on what looks to be a 1964ish Olds Dynamic 88...its kinda been neglected, but all the essentials are there..aka, drove when parked. Now, I know you need to have fuel and spark to get a car firing and running, but the thing that is setting me back is the carburetor. I'm not too fluent in this language, and the last one I had a hand in tinkering with was on CarKid's and mine Yugo.
Question:
Is there a quick way to overhaul or tune up the carb? We got it to run for a few seconds with some ether (starting fluid), but it does not seem to be getting fuel...I'm guessing its gunked up a decent amount. Taking it off shouldn't be a problem, I've got tools at home. Its a GM 2-JET Rochester carb, and it just looks like not all the throttle linkage is hooked up right. I dont know if I can get pics tonight but if there is anyone that has experience with these or is good at step by step carb stuff I would really appreciate it.
PM me or post up...I really appreciate it your help.
Check the little screen in the fuel inlet. Throw it away and install and in line filter. Pull the top off the carb and spray all the ports with carb cleaner.
Of course there is the problem of old gas
You can get a rebuild kit with instructions from your local auto parts store.
I may be way off here, but I've had a few old cars and none were ever gunked up enough not to run. I would suspect the fuel pump first. Have you removed the fuel line and confirmed that its pumping fuel as you crank over the engine?
If you need any kind of parts most likely the parts store will need the carburetor number that's (hopefully) on the brass tag attached to one of the top cover screws.
More than likely it parted company eons ago and you will have to throw yourself on the mercy of the parts guys. As much info as possible will help; mfgr, 2v or 4v, etc., etc.,
I would agree that it takes a lot to gum up a Rochester 2GC to the point where it won't run at all. Make sure the fuel pump is working - disconnect the line from the pump to the carb, stick it in a can and crank the engine to make sure it's pumping good. If it is, you can pull the top off the carb and make sure the float and needle aren't stuck and the bowl isn't full of gunk. There are eight screws, and you have to unhook the fuel line, choke and power valve linkages on the carb exterior. Be careful you don't tear the gasket. Make sure the float is not 'sunk', i.e. they can sometimes develop a pinhole leak that will let it fill up with gas and then it won't work. Parts store carb kits aren't very good any more, If you do a full rebuild I'd recommend getting a quality kit from Jon at The Carburetor Shop in Missouri. http://www.thecarburetorshop.com/
edit: there's a 1964 Rochester 2GC manual online here: http://www.oldcarmanualproject.com/manuals/Carbs/Rochester/2-Jet/1964Manual/index.htm
2GC's are easy as pie to work on.
Nice carbs, last forever, got one on my Jeep.
