Should I attempt to rebuild my carb?

If my jeep dosn't start up and its getting spark, then it must not be getting fuel. Should i attempt to rebuild my carb on my own? I know its a ton of small parts and very aggrevating. Anyone know off the top of their head how much the rebuild kit is for a Rochester 2bbl on a 225? I may be wrong, but is it about 200 to get it rebuilt?

 

It's about $20 for the kit, $10 for a can of compressed air, and $10 for a carb cleaner dip bucket.

Are you sure you're at that point in the troubleshooting?

 

Just "getting spark" isn't enough. It needs to be a strong spark... If that's all good, then: Are you sure it's even getting gas at the carb? If not, try disconnecting the outlet side of the fuel pump and turning the engine over. There should be fuel pumping out. In an earlier post, I thought you said it had been 15 years since it last started. If so, whatever fuel was in the tank/ lines/ pump/ carb is all varnish and probably useless from a combustion standpoint. Not to mention it may have gummed up the small orifices in the carb...

 

:iagree:

You can bypass the fuel pump and fuel lines by hooking a length fuel hose directly to the base of the carb and having a freind slowly pour gas into a large funnel held above the level of the carb. Gravity takes care of the pumping as it were. If it don't go with that then you might consider the carb suspect.

FWIW, my Jeep had only been sitting for about 4 years and the fuel pump was shot.

 

Don't dare pay that kind of money to get it rebuilt. If it definately needs it, and you can't do it, I will do it for you. postage and parts is all it will cost.

 

Cool, I planned on re-building it myself anyways either way, I just figured I would ask your opinion and I didn't want it to be biased. I'm not sure if it needs to be rebuilt, but I'd need it anyways for a good running engine, so it won't hurt at all. And if I do it now, it will narrow down the "no start" alot, if it dosn't fix it. I am not using a fuel tank yet, I'm just pouring gas into the carb. Factoring in the fuel delivery is not something that I need right now. Is there any way to find out if gas is getting through the carb? Can I take it off and just pour gas through it? I was just on the hunch that since my friends 232 turns slower then my engine and still catches fine, and we fixed the spark, then its gotta be gas. maybe gas was in the carb for 15 years and turned hard and waxy. With that being said, and the fact that I'd want a rebuilt carb eventually anyways, I think thats my next project. What is the preferred company to order rebuild kits from? Also, whats the deal with starting fluid? Why would starting fluid work when plain gas wouldn't? Is it extra corrosive or something so it would penetrate through clogged passages where gas wouldn't? I don't get it? Anyways, where do I get the rebuild kit?

 

Check throttle shaft play first!
Grab the shaft and wiggle it up and down, back and forth.
There should be NONE to VERY little play in it.
If excess play exists, you'll be chasing your tail trying to get it running right because of a never-ending vacuum leak that can NEVER be compensated for.
Don't spend money on a rebuild until you check that.
To fix that, the carb. body will have to be drilled out and bushings installed.

The Rochester 2 bbl. is VERY easy to rebuild.
I just did mine. There's not much in that little unit at all.

Best of luck!

 

rebuilding the roch 2bbl is not bad. if you haven't done a carb rebuild before just take pictures of each step as you take it apart for reference later.

keep all the old parts until you are finished so you can match them up with the right part in the new kit. sometimes kits come with extra parts for different versions of carbs.

get some heavy rubber gloves and a parts brush in addition to the cleaning stuff and air mentioned earlier. and wear eye protection if you are going to brush the parts with carb cleaner.

i would recommend reading through the instructions first and consulting both the package instructions and fsm instructions if you haven't done it before. but then... i'm a little retentive....sometimes...

 

I paid the $75 to have mine rebuilt. No headaches and I could do something else to the JEEP while that was happening. To me, it was worth it.

Oh... It's a rochester 2 bbl
