carb id
i just bought my 50 merc f68 a couple of weeks ago.i was on another site that i found before this one,there was a carb id chart there but i couldnt match my carb with any of them.my carb has the ford script on the passengers side but nothing on the other side of the bowl.however there is a "94" stamped on the firewall side just above the 2 ajusting screws for the air/fuel mix.is this a holly 94?i will need a rebiuld kit for it and need to know witck kit to get.
thanks abain for all the help,im still amazed at all the info and help on this site compared to some others ive seen.

Three bolt base? Undoubtedly a 94. Although there are many subtle variations of 94's between cars and trucks, the innards are virtually idential. There is little reason to get a 7RT-xxxx vs. a 8RTxxxx or whatever. The key things things to look for on your carb are: existence of an extended shaft on the driver's side for a throttle cable, along with a lever and spring-loaded cap; whether the air cleaner mounting is double-tapered or straight. For a rebuild kit, all will be the same in the BonusBuilt years. I would check Vintage Speed for a quality kit.

In a rebuild, one of the key areas that is difficult to clean, but makes a world of difference, is cleaning the "dip tubes" where air is bled into the gas drawn thru the main jets. The space between the outer tube and the inner tube, as well as the tiny holes in the outer tube, get packed with junk and are very hard to get really clean. Soaking and some time with a copper wire strand pay big dividends in economy and smooth operation. (see sketch)
You asked for the time and I've told you how to build a watch, oh well! The complete manual for these (actually for later models of the same basic carb) is here:
