The ice bike would get better grip if the saw blade was turned around. Bonzi Lon

I'm still leaning to air getting in from the throttle shafts. I know the bearings & shafts are new, however some out of tolerance parts make it past QC. To me there is a spot at half way where air enters. Like it is oval in one spot, sealed at idle and wot, but lets air in at that spot. The grease trick should seal them enough to get a pull or two. Thick enough to hold a seal and high temp so it doesn't melt off. A minor mess. Bonzi Lon

Welcome. That smile looks familiar. What would the VIN be & build date? Bonzi Lon

Zedyone, did you try the trick I mentioned in post 196? It should seal any air leaks around the throttle shafts. Then you can try a different pair of carbs. Bonzi Lon

In 1980 my brother found an unusual car & bought it for $800. It is a 1965 Alfa Romeo Giulia Spider Veloce. Another sexy Pininfarina body. It is still in his garage, in pieces, waiting for me to acquire, someday, maybe. Bonzi Lon

Jared, I remember your car from Z-Con10. How could one forget that machine? Congrats on the sale. I sold HLS30-00110, blue/blue in Aug. It got shipped to Dubai also, to go with his 12 other 240's. Again, great build, that one will be hard to top in my opinion. Bonzi Lon

The first go round the gaskets were installed dry, there was plenty of compression, everything looked good. After it was together was when everyone said it should have some type of 'sealant', to prevent fumes. I had fumes. I looked at the old gaskets and there was residue of glue on them. They got glued on this time. (the fumes were from leaks in the entire exhaust system, since replaced). Bonzi Lon

Time the cold start up with a real watch. I think the 'couple of minute' is a slight exaggeration. My 73 with new carbs takes a while to fire after sitting 2 weeks or so, haven't really timed it because I know it is a carbed engine. It just seems to take a lot longer because I'm so used to the fuel injected Saturn, split second ignition. Bonzi Lon

I used the yellow 3M Weatherstrip Adhesive. Some call it elephant snot. Get a good seal completely around the gasket, this is where exhaust fumes will creep in from bad or no seal. Bonzi Lon

My front end wobble was caused by a loose self locking nut on the top of the shock rod. It ruined the 'D' shape in the insulator & the shock rod was 1/2 eaten through. It was found by jacking the car up & down on that side & watching the whole assembly move in & out. The black cap covered the nut that was held on by about 4 turns. Bonzi Lon

Your list looks right to me. The metal bladed cooling fan was on the very early cars & painted off-white /antique white. They were replaced with the white plastic fan when the metal fans were reportedly flying apart. Your 73 should have the plastic fan. Bonzi Lon

I remember reading somewhere it was either in 77 or 78, still needs to be confirmed. When my engine was rebuilt in 1980, they told me the new bigger cam would be 'internally oiled & do away with the spray bar'. At the time, it was over my head, so I just nodded. Bonzi Lon

A quick but messy trick. Get some very thick high temp grease and run a good size bead around each of the throttle shafts where air COULD enter. The grease should close off any air or suck it in. Bonzi Lon

The crank snout bolt is 27mm or 1 1/16 inch. Bonzi Lon

Welcome to the club. You are making great progress. I agree on the Corvette comment, I had a 75. It ran like a scaled cat, but the rest was a piece of junk. Cost me a small fortune. I told everybody my Z was 10 times better than that 'squeaky Vette'. I have a thing for 73's. What would be the VIN & build date be? Bonzi Lon

As a confirmed bachelor for over 38 years, you guys need help. Blue is the exception, I'm trying some of them. Hotplate, microwave & a George Forman is all I need, and all the years of experimenting. One of my 'no heat' favorites is a peanut butter & mayonnaise sandwich. Bonzi Lon

The manual fuel pump works fine with the round top carbs, the electric was added to help prevent vapor lock with the flat top carbs. I had both, but not any more. Video testimonial: I've never been in a carb before in my life, watched the video twice. Removed carbs, cleaned, adjusted per instructions, reinstalled, got the bowls full from a can and it fired up withing several revolutions. Happy dance. Minor tuning & timing. I now know how & why they work, so simple now. Bonzi Lon

They go to the very front of the frame rail. The black brackets at the bottom of the photo, outside of the bottom of the radiator. Bonzi Lon After looking real close at your frame rails, the bolt holes should be where the ratchet is. Are there signs of replacement of the front rail across or leading back? Bonzi Lon

Mowing is so over rated. Bonzi Lon

PCV can be checked by blowing through each end, one way is open the other way it closes. Bonzi Lon

When my cam was replaced with an internally oiled one, the dealership used block off plates without any gaskets. If this is not a highly modified engine you might look at "How to Rebuild (not modify) your Datsun & Nissan OHC Engine", pages 106-107, Inspect & Install Cam, & photo 6. Several points to take into consideration. Bonzi Lon

On the induction, it is claimed (internet & bench racers) that the N36 intake manifolds flow a bit better & maybe a few more cc than the other 3 available, also has the water connections. Bonzi Lon
