My 75 Pig - Look and See

[75PIG]

I would find a 74 ish carb. you will need a clamp style airhorn(F engine only) carb inorder to use the 69 vintage manifold, since as you discovered it doesnt locate the carb properly for the 2F air cleaner.

you will need to find/make the return line for the carb if you go with the 74 carb.

Cool piggie. Looks clean!

What is a clampstyle air horn carb -- do you have a picture or reference? What kind of air cleaner do I hook up to her if I keep the 69 intake manifold? Do I plug the vacuum port on the 74 carb if I can find one as well as the vacuum advance port on the distributor?

Rhino mentioned JIM C to get a carb from --- does he have an alias?

Again -- thank you all for all the informtion -- this is great!!!!!

How are you going about running the return line on the Weber? Or did you decide to go with an LC carb? You can make an orifice type return using some brass fittings with a "T" and a small slice of vacume hose wedged into the fitting. It's kind of hard to explain, unless you get my general drift. The piece of vacume hose works as a restrictor.

they actually make those "T"s , should be available anywhere, just a brass "T" with the one side haveing a small hole instead of full flow.
holding one in my hand right now, looks like about a 16th" hole

Maybe a bad assumption, but I was going to hook the return line to the "other" side of the Weber. This would be directly opposite of the fuel line input. I assumed that was hopefully what the other port was for. See Picture No. 2 above.

Madoc1 -- on your 38/38 is it similar in hookup?

I would not need a "T" if indeed that was what the other port on the Weber was for. Any ideas.

Thanks again

Is that fitting pipe thread or compression?
As far as using the port you're talking about as a return, I guess as long as it's coming from the bowl you should be fine, but I'd have to see it to know for sure

 

[madoc1]

yes the set i did was just about like that. two5/16 or so fittings on the top front of the carb. dont have the truck here to look at, sure seems. just shortened the
original lines to about the water neck and add gas lines, zip tie and your are good to go.

all right, went and looked at the carb. just like yours. only both outlets/inlets were on drivers side looking from the front. top one was plumbed to fuel pump,bottom to the return line. i have crowed about this before, it came from jt, who claimed it was one the last in the u.s.. due a labor disagreement somewhere. ANYWAY , one beer later, it also has dual fuel cutoffs. it has worked out very well. jim

Treat with more pictures.

Still puttering. I hooked up the return line --- blew compressed air through 1st to see if it would flow freely to the tank... it did.
The results were the same -- burns pretty rich. It runs pretty well with lots of pickup -- into the drive it started to hesitate on me and at idle when I accelerated in neutral it would blow "black" smoke. Pictures are of the Weber return line hooked up and the #2 spark plug -- 2F engine set gap at .039. As you can see, it is fouling -- burning rich.

Thanks for all your suggestions -- will still need to advance timing as suggested by Rush55.



Guess I may have to rebuild this carb or get a rebuilt from Jim C. Lots of Jims. Me too.
