I finally got around to putting the carb I rebuilt months ago on the Jeep today! I took the old one off – no problem, except that one of the manifold studs came out in the process. I tried everything I knew of to get the nut off of that thing so that I could re-use it, but it wasn’t going to happen! I had all but given up when I remembered the rebuilt head I had sitting up on the shelf. I went and checked – YEP, it had both studs in it! I put a second nut on that stud and pulled it out. I put a dab of Loctite on it and installed it in my manifold and put everything back together.
I hit the starter and turned her over a couple of times to get some gas in the bowl, then turned on the switch and she fired right off. Then died. After a couple of rounds of this to figure out how much choke and throttle to use, she was purring along at a high idle!
I let her warm up a couple of minutes, then took off up the driveway. I got her good and warm and then went back to the shop. After a little fine tuning and adjusting the throttle and choke stops, she was idling at a low idle without the miss that has been present since I fired her up for the first time over a year ago!
I took her for a ride up the driveway again, and she now has a good bit more power – I can spin the tires without a problem, and catch second (this is on a dirt driveway, mind you!)!
Then I fixed the hand throttle that wouldn’t hold. I tuned it a little in the dash hole and straightened out the cable a little – works fine now! Then we took her for a spin around the field – a fast one! She did great! We went out on the highway for a short distance too (I didn’t have my driver’s license with me) – I was able to get her up to 35 in second before I had to turn into the driveway.
I still have the hesitation when I blip the throttle – may be a timing issue. My windshield wipers work much better now also – must have had a vacuum leak in the other carb. I also have that annoying bellcrank problem (death wobble) I need to do something about. And, of course, the puking rear pinion seal!
Well, that’s about it for today – back to work tomorrow night!
