    Coil is in stock position mounted upright next to the intake.

    As luck would have it I blew out the fiber style exhaust donut. Found that I had put alot of strain in the system. Added another hanger and let the system "hang" where it will, then tightened everything up. It's not good for any hard trail running cause it going downhill and the muffler drops below the frame. Other than that I think it's good......haha, we'll see! I really don't want to replace it, although a good muffler shop can do wonders.

    It was a good day and a bad one..............

    The good;
    After redoing the exhaust I found the Weber needed a total rebuild and I just happen to have one freshly rebuilt on Wilma.

    The bad;
    There's a problem in the idle circuit on it, but it runs decently enough that I can drive it.

    The good;
    Other than the idle burble it runs awesome, clean smooth power throughout the whole RPM range.

    I'm waiting of complete rebuild kits now and will go through my Weber stash for a better body with less corrosion in it.

    Took the other 32/36's apart today and took the best main body I had and did a complete cleaning and between the 2 I have a rebuilt and functioning Carb. First test drive was good with a stop after full warm up to readjust idle and mixture. Power is smooth and crisp...I guess I've needed to rebuild the carb for a LONG TIME, its a completely different animal now, it accelerates smartly now.

    I rebuilt the new design Weber that was leaking and this is a completely different 32/36 than the 4 Spanish versions that I have stock piled, so there's a bit of a learning curve on it, and first run with it newly rebuilt was a failure. My idle jets are to small and it's running REALLY lean according to the plugs and how it drives. Pulled it off and replaced it with the early version that I had already rebuilt, it wasn't jetted right, but I have a ton of jets for that model, and here is where I ended up. I need to do an AFR gauge to get it better, but it's running pretty good like this. Primary is 75 idle, 165 main, 180 air corrector/ Secondary is 70 idle, 160 main, 170 air corrector. With this jetting the volume screw is just under 1.5 turns out, that's within spec, and there is no hesitations during off idle transition or when the secondary comes in. An off idle full throttle hit doesn't report a lean cough, and acceleration is smooth with no hesitations right up to redline. It doesn't smell rich and the plugs seem happy with it. I will do a mileage check over the next few weeks and see if it's still in the 18-19 mpg on the highway, but I'm callin it good for now...at least till I do an AFR.

    That sounds right to me. I'm betting you're in the money.
    I was surprised at how much jet these engines take.
    When my buddy cammed his 154, I kept going bigger and bigger, one step at a time... like 4 shots in a row. Then got tired of messing with it, and went to what I expected would be too big. Turned out to be spot on. lol
    Cool to see it back on the road! :beer:

    Haven't really done anything to it for awhile. I even stripped her down and put her up for sale, dang near sold it too! Had a guy hot and heavy for her and ended up talking him out of it. That being said...I couldn't do it!!! I really don't have the room but I can't sell her. I guess it's time to start putting her back together, fix the Tcase leak, and start driving her again...kinda got spoiled by the Ranger I bought.

    Kinda got back on her today. Remounted the hi lift back on the hood and found a good passenger vent cable on ebay the other day, so today started the revamp of the heating/vent system. I replaced the bad cable on the passenger side and move the drivers cable to a different hole for a little better movement. I also added a choke and heater valve cable that I've had in my stash. I still need to find a throttle cable and fab some way for it to work on the Weber, then all the holes in my dash will be filled. The seals came in for the Tcase and I plan to replace them this week so she's back on the road instead of leaking in the driveway.

    Finally got to the Tcase rear main seal...what a PITA!!! It must have been the original cause it was hard as a rock, took forever to get it to back out, had to use a chisel to cut it to release some tension. When I moved it the other day I noticed an exhaust leak, turns out the muffler needs to be replaced now, I have one for it cause I knew it was gettin old. So I ran to Napa and picked up another donut and on the way back the Ranger blew a heater hose so I spent the rest of the day fixing it. That truck has more hoses and pipes on the engine than anything I've ever seen. Turned out that someone put the clamp on the hose next to it with the tangs sticking in the heater hose that blew, I guess attention to detail isn't in demand anymore, I mean how hard is it to pay attention. Either way the Ranger is fixed and it should be nice tomorrow to work on the Scout.

    Started on the exhaust today, reshaped the head pipe so its centered from the manifold and have decided to move the muffler to a less "rock-rashy" spot.

    Finished the exhaust and moved the muffler back a bit but left it under the passenger side. The new muffler had a much smaller footprint than the one that was on there. Took her out for a buzz and I think my gas is going bad from age, popping and lurching on acceleration...will mess with it tomorrow.

    Been busy and got to Beater again today, it appears that the old muffler was plugged enough to effect the tuning of my Weber cause now it's running lean. With that, I've been doing a TON of research on the 32/36 and now have a better working knowledge of its operations and tuning. I pulled the old Spanish Weber off and turned to the newer style one I have with a manual choke. I could never get this carb to run right on her and I finally found out why. It turns out that the secondary butterfly stop was adjusted to far open causing all of my idle adjusting issues...to much vacuum signal. I got that worked out and now with a #90 "fat" main idle jet she's perfect at idle!! Mixture screw is at 1.7-2.0 turns out with the idle speed screw not in contact with the butterfly. She runs like a tractor there and will barely idle at 350 rpm but she idles. Idle speed screw is now at .35-.40 turns after contact and she idles at 750 rpm at operating temp. I didn't get to go on a test drive yet, but I'm pretty happy with the results so far...I now know that the idle circuit is correct...it gets easier from here.

    to be continued...................

    Sold my CB750, so I bite the bullet and order a new clutch for her, there ain't much left.

    this has been some great progress!
    Which clutch did you go with? Finger or diaphragm?

    Parting with your CB750... that must have been sad. Great bikes! :beer:
