Carb problemo
Hello. My 68 f100 360 cid has got blow by really bad. And the carb is in pretty rough shape. It putters and has a lot of hesitation when i give it gas. I have rebuilt it before and have tried new gaskets in the past, but I have decided that i am going to purchase a new one. Well my engine is pretty much stock besides the headers. I want somethign that will bolt right up to my stock manifold and not have a problem with all the linkage and such. Whta is the stock CFM for my truck. Any suggestions... I care about it running better and gas millage opposed to power. Thanks and please any suggestions on good carbs out there I would appreciate. Any on ebay that you all know of... New ones? I am looking for the BEST carb for for this truck. Thanks.

I have a 500 CFM holley 2300, which is rather large for my truck, but they have 350 CFM versions, and they are $225-250. Mine works flawlessly, except for the idle mixture screws shakin loose sometimes, but thats cause I took the caps off. Cold weather driving is not bad, and she cranks most of the time without pumping the gas, and when I do have to, it only takes one pump and hold to the floor.

If you have a lot of blow by, you're just whizzing in the wind. The only time you should "replace" a carb is when the throttle shaft and/or the bore it rides in is worn out. If your shaft is in good shape, rebuild it- make sure you dip it and blow out all the orifices- and run it until you can have the engine fixed.
Don't waste your money- The carb is the last link in a chain- it should be the last thing you look at when experiencing a driveability problem.

If your engine is real tired you may not have a good enough vacuum signal for the carb to work properly. I agree with jds1971 except I quit dipping carbs years ago and I now just spray the passages with Berryman's B-12 and then blow them out with air. I find this works just as well, but I only do it because I can't stand the smell of that dip and you can't get the smell off of you. It gets into your clothes and everything. I even wake up at night smelling it after scrubbing most of my skin off. Nasty stuff, haven't used it in the last 50 or so carb rebuilds. If the outside is really cruddy I take it to the parts washer before dissassembling.

That is good to know. I haven't even tried it in at least a dozen years. I am a fussy old fart for a mechanic, I hate to get gasoline on me and the worst os gear lube. I gave a really nice Cornwell coat to a street person because it got a little gear lube on the arm and after washing it 4 times I could still smell it.
