racerx Posted January 6, 2013 Report Share Posted January 6, 2013 Dist. number on dist is D417-67. I'm certain its for a Datsun but not sure if it will fit my 510. thxs. Quote Link to comment
ggzilla Posted January 6, 2013 Report Share Posted January 6, 2013 That's a honda distributor. Hitachi D41 type. Looks exactly like a Datsun 1200 distributor. Does it have a Nissan part number? 22100 should be stamped on the housing if it is a Nissan. Quote Link to comment
racerx Posted January 7, 2013 Author Report Share Posted January 7, 2013 Checked it again no nissan number...datsun 510 rotor and cap fits the distributor. What can else can I look for to see if the dist. is for a Datsun 510? Quote Link to comment
ggzilla Posted January 7, 2013 Report Share Posted January 7, 2013 It's not for Datsun 510: * Hitachi D417-67 is for Honda Civic * All Hitachi D40/D41 distributors use the same cap * Datsun L-series engines don't have a gear-driven distributor Quote Link to comment
racerx Posted January 7, 2013 Author Report Share Posted January 7, 2013 The one i have is not gear driven and its slotted Quote Link to comment
banzai510(hainz) Posted January 7, 2013 Report Share Posted January 7, 2013 this might fit if you have the matching pedaatal and timming plate.key is line every thing up at TDC and see if the rorot lines up on a plug wire. If yes youll make that #1 plug wire then go 1 3 4 2 counter clockwise fire order. Quote Link to comment
racerx Posted January 7, 2013 Author Report Share Posted January 7, 2013 How much vacuum does it take to move the advance parts in the dist. I am trying to bench test before I install. Quote Link to comment
banzai510(hainz) Posted January 7, 2013 Report Share Posted January 7, 2013 suck on it with your mouth. if it sems sealed just run it. I would ck to cka sure the plate moves with your hand. as for what it takes. I dont know the carb doesnt pull alot of vacuum anyways. I run them w/o somtimes. Most is centrifical adv anyways. dont make this that hard Quote Link to comment
racerx Posted January 7, 2013 Author Report Share Posted January 7, 2013 yeh may just have to install it and try to see if it works. Quote Link to comment
ggzilla Posted January 7, 2013 Report Share Posted January 7, 2013 It takes 6 to 9.5 inHg typical. Just push on it and see if it holds vacuum on your finger. If not, new VA can is only $30. Quote Link to comment
banzai510(hainz) Posted January 7, 2013 Report Share Posted January 7, 2013 Just push on it and see if it holds vacuum on your finger? must have a IQ of 160!!!!!!!!! Quote Link to comment
ggzilla Posted January 7, 2013 Report Share Posted January 7, 2013 It's a better test than sucking on it, because it also tests whether the advance mechanism is froze up. Quote Link to comment
banzai510(hainz) Posted January 8, 2013 Report Share Posted January 8, 2013 Yeah Ive dont this to but I forgot about it.YOu just reminded me on how to ck it. Quote Link to comment
racerx Posted January 8, 2013 Author Report Share Posted January 8, 2013 Has anyone tried this or heard of them. http://www.hot-spark.com/1-HS-HIT4-Distributor.htm Quote Link to comment
ggzilla Posted January 8, 2013 Report Share Posted January 8, 2013 Yes, they are similar to Pertronix. Hitachi kit is at http://www.hot-spark.com/1-Hitachi-Distributors.htm It is a points-replacement unit. Unlike the factory Matchbox distributors it is low amperage. It "Works with stock distributor and coil" or can use their high-voltage/low current coil. What you can't use is a regular high-energy (high current) coil. Just like the Pertronix Ignitor. Only the Pertronix Ignitor II is high-current and so can use an 0.7 amp EI coil. I haven't had any reports from people actually using one. Quote Link to comment
racerx Posted January 10, 2013 Author Report Share Posted January 10, 2013 found out that the hot spark needs higher ohm like 3 ohms +, currently have flamethrower (pertronix) and only 1.5 ohm. If I go with Hot Sparks distributor more than likely have to install their coil or find something similar ohm reading or install a ballast resistor that is rated at 1.5 ohm. If the distributor I have that's been ID as a Datsun one and does not work may have to buy their distributor. I'm having a hard time finding a single point dist., called NIssan dealerships, Oreilleys, AutoZone, NAPA. and more. Quote Link to comment
ggzilla Posted January 10, 2013 Report Share Posted January 10, 2013 Hot-Spark will work with the stock Datsun points coil with ballast resistor. Or you can get an L20B matchbox with pedestal at Pick-n-Pull for $40. Quote Link to comment
banzai510(hainz) Posted January 10, 2013 Report Share Posted January 10, 2013 Racerx gert a know Datsun guy in your area to help you. This is EZ to get running. If your truck has power to the blk wht wire with key ON and has pwer to a wire with key in START thats all you need the the truck to get this running. I dont know the color on the HOT start for the ealy 521 but mine was the blk red wire(thats has 2 wires goin in toa lug) This might be cut up and changed now. persoanlly I think you can get what you have working. If you just hook it up per Mikes photo Quote Link to comment
racerx Posted January 10, 2013 Author Report Share Posted January 10, 2013 thanks for the help..the 510 runs okay, not truck, it's my vacuum advance that's not working. In order for my petronix to work it needs a single point dist. and can't find one on line or auto stores. I do have one single point dist. lying around that I bought (used) and will run that one on my car and hook up the petronix ign. system. then check with timing light to see if timing will advance. As far as Hot Sparks, they recommend hi output voltage coil with higher ohms, like 3 or so, that typical, with their distributor and I don't think the stock one is hi output voltage.

banzai510(hainz) Posted January 10, 2013 Report Share Posted January 10, 2013 hot spark China/Pertronix USA you use the stock coil and ballast resisitor Quote Link to comment
ggzilla Posted January 10, 2013 Report Share Posted January 10, 2013 The Hot-Spark "recommended" coil is high-voltage but not high-current. It's an overdriven coil. The matchbox uses a real high-energy, high-current coil. Yes, the Hot-Spark web page says you can use a stock points coil. The stock coil is 1.5 + 1.5 resistor = 3 ohms. Vacuum advance is not needed. It helps with part-throttle driving, but will run OK with the hose plugged -- and will make just as much HP. Quote Link to comment
racerx Posted January 10, 2013 Author Report Share Posted January 10, 2013 checked autozone for stock replacement, coil primary 1.2-1.9 and ballast resistor .8 ohm. Does not add up to 3 ohms needed by hot sparks. Quote Link to comment
racerx Posted January 10, 2013 Author Report Share Posted January 10, 2013 good to know that vacuum advance is not needed. Then I should just not even bother with it. Current distributor works with petronix, flamethrower coil with ballast resistor. But vacuum advance not working. Quote Link to comment
ggzilla Posted January 10, 2013 Report Share Posted January 10, 2013 Good question about the resistance. Datsun Factory Service Manual says nominal 1.5 ohms resistor, 1.3 ohms coil. So the Hot-Spark coil is even less powerful than a stock Datsun points coil. Quote Link to comment
racerx Posted January 10, 2013 Author Report Share Posted January 10, 2013 yes that's only 2.8 ohms...but I think it's the voltage output of 40K or more is recommended. And 3 ohms + that is needed. In short, hi voltage output 40K or more recommended and a MUST for coil resistor of 3 ohms+ or else as said by HotSparks tech guy that running lower will burn our the elec. ignition.
