[oldblue1968chevy]

okay, my gmc parts truck had an edelbrock carberator on it, well, this afternoon after school i decided that i'd take it off, well took it off, and it looks pretty gunky in some spots, id say the carb is 3-4 y o......well dad said i should rebuild it before i reinstall, (inside is a lil dirt looking, and appears to have a wee bit of OIL in it)...well, im 16 on a budget.....and the trucks only been sitting 10 months, so i ask, how much a rebuild kit would be, he thought 20 bucks or so, well i looked on summit.com and a rebuild kit was close to 45 bucks....

so should i rebuild the carberator before i put it back on? or should i put it on? and what're the pros and cons of this?

also, it hads a plug for an electric choke, my quadrajet 4bbl is electric choke also, but doesnt have wires going to it, edelbrock has a male plug on it on the electric choke....

sorry for the long post but thats just my current predicament now, i hope i spelled that correct haha
