It also allows you to then get a 6-sided socket over them vs a crappy open end wrench. Your exhaust manifold looks a little different than when I did mine. I can’t really tell. Maybe the M14 plugs won’t work? Measure the OD of the plug threads once one comes out. Dude youre so smart. The crimping worked great! This will work for me until I do the new Weber. When I take the old carb off I will have much better access to fully remove these fuckers. I was able to easily remove the inlet to the intake and the inlet to the carburetor. Will grab some caps for those today as well as tubing to replace the ancient fuel vapor return lines. I also removed the hot air inlet to the air filter. I live in temperate CA and its never cold enough for this. Probably keep it for original parts reasons unless someone here needs it. 1 Quote Link to comment
andyZ00m Posted November 26, 2023 Author Report Share Posted November 26, 2023 Turns out the plugs were 1/2”-20. Seemed the they were tapered a bit too. The 1/2” plugs went in fine though and I stoppered up the air intake with a rubber stopper! Replaced the fuel vapor lines and clamps and we’re good to go! Got the old (Chinese reman) alternator back in I think it’s buttoned up for a couple weeks while I source more parts! 1 Quote Link to comment
andyZ00m Posted November 27, 2023 Author Report Share Posted November 27, 2023 Holy shit, she runs so nice. Got the carb dialed in back with the Chinese alternator and it sounds so much happier without the smog pump. https://i.imgur.com/CLbRFVb.mp4 5 Quote Link to comment
mainer311 Posted November 27, 2023 Report Share Posted November 27, 2023 (edited) There’s someone selling a matchbox distributor on Facebook right now for $150. The page is called “Church of L Series.” The user selling it is legit. His name is Mike Malone. He’s a well known Mikuni carb rebuilder. Just throwing that out there. These things get snatched up pretty quick. Edited November 27, 2023 by mainer311 1 1 Quote Link to comment

mainer311 Posted November 28, 2023 Report Share Posted November 28, 2023 Nice. When you put that thing on, try to clock it so that the matchbox is farther away from the exhaust manifold. That’ll keep the heat away from the electronics part of it. 1 Quote Link to comment

andyZ00m Posted November 29, 2023 Author Report Share Posted November 29, 2023 Thinking about the alternator upgrade eventually, will this model type work? Says regulated and 60 amp. Remanufactured in Japan, original Hitachi. https://www.ebay.com/itm/285220192538 Quote Link to comment
datzenmike Posted November 29, 2023 Report Share Posted November 29, 2023 It will bolt on but it's a larger diameter than the original and there is not really enough room on a truck. There's the lower radiator hose, the frame and the idler arm right below it. The 620 is similar and I got one on but it was a poor fit. The cooling fins wore a hole in the hose and when tensioned the alternator bumped the idle arm. I had to put the belt over the pulley first then bolt it on. You may have better luck than me.

Yeah I was able to fit the one from the 200SX which is the same size as this one. That one had the broken regulator so I had to pull it. thanks for the heads up. Seems like the area where the smog pump was would be a better spot for the alternator on these trucks… Quote Link to comment
datzenmike Posted November 29, 2023 Report Share Posted November 29, 2023 Back in the 'mid '70s my alternator bracket snapped both bolts off in the block. A friend made a bracket that fit where the smog pump would have fitted and moved it over to below the distributor side. Much better spot. 1 Quote Link to comment

Someday if/when I put a L20b in this thing I’ll rethink the whole layout and electrical scheme. It’s working great right now with the Chinese 35A alternator. Quote Link to comment
mainer311 Posted November 29, 2023 Report Share Posted November 29, 2023 Alternator on the exhaust manifold side sucks too. All the roadster guys relocate them away from the heat. Quote Link to comment

Maybe the room is cramped in a Roadster engine bay and probably they make more heat, tons of room and lots of air circulation from the fan in a 521. Quote Link to comment

He gave me some great info and showed me some of the Mikuni stuff he works on and a few engines he’s building. He has SOOO many carburetors!!! Haha. Some nice Dattos too. we didn’t put the matchbox in there as I need to wire up some new connectors and put the new coil in but will tackle that this weekend. 1 Quote Link to comment
