ODD FIRE TIMING FINALLY EXPLAINED Prt. 1

[@rickdeyoung8886]

This video popped up at the right time I’ve had a odd fire Buick for 22years and have been baffled about how and why it ran the way it did . Aftywatching this I went out and made a few adjustments and it has never run as well as it does now thank you for doing all the hard work to put this video together

[@carlbouthillette198]

Jason, will keep you posted. Headed up to Colorado to spend a week on Jeepster....will keep you posted.

[@takingbackmejlk]

thank you soo much, very exciting to get things working the way they should, let me know if you need anymore help, sorry about the late response youtube is not notifying me of the comments but I will try and check them as much as I can.

[@robinreynolds4862]

Great job, your a genius

[@takingbackmejlk]

Not so much a genius just relentless in researching, it took me 6yrs and blowing a motor for it to set me into motion to figuring it out. I have to give most of the credit to the reference link I provided to britishv8 they had clarified the points being designated to odd and even cylinders, without them I'm not sure I would have figured it out entirely, the rest of the footwork on the cap and explaining everything I had put together but I couldn't have done it without them. Hope all who come here can at least take something from it. Thanks for the comment! Have a wonderful day!

Absolutely Feckin Awesome

[@takingbackmejlk]

thank you soo much, a culmination of a lot of time and energy, glad it can assist

Your video solved my back firing problem on my 71 CJ5 w/ Dauntless 225 Odd Fire. I just couldn't figure out why I couldn't get my engine to run right. Just rebuilt with new distributor. But we put it back the way it came off. I rearranged the spark plug wires and clocked the distributor per your diagrams and bam! She purs like a kitten at low speed and high speed. Thanks!!!

[@takingbackmejlk]

I'm glad it helped! I am going to post a vid that explains how to properly drop in the distributor, going over making sure your not 180° out and your on the compression up stroke etc. I'm in the process of editing it but my schedule is all over the place so I'm not sure when it will be done, I will post it as soon as I can.

[@takingbackmejlk]

I also did the same thing on my first oddfire rebuild, I put my distributor back the way it was removed and the person didn't have it set right either, it was facing at the driver side cylinders. I spent years having problems with my timing and inevitably I blew an engine because of prolonged misfiring and of course information on how these work is non-existent thats why I put this video up because if I couldn't find any clear way of setting these things up then I knew other people were having the same problem just based on how many ways I saw other people setting them all up differently, it didn't make sense why so many people had them facing differnt directions and having the #1 wire on all different terminals.

2nd ODD FIRE DISTRIBUTOR VID "HOW TO INSTALL" kzbin.info/www/bejne/i4LUYZh-ptWpedE

[@-oiiio-3993]

The Odd Fire ignites at 90 and at 150 degrees of rotation, rather than the 120, 120, 120.. of a 90 degree V8. The 'short' and 'long' duration represents ignition timing of 90 - 150 - 90 - 150 - 90 - 150 degrees of crankshaft travel as opposing cylinders share crankshaft journals.

[@takingbackmejlk]

absolutely, i didn't want to get too technical with everything so that everyone could understand the basic operation of it, there's so many things you can go over with these engines like 2 pistons per journal set at 30 degree intervals to get the 90 and 150 firing sequence unlike the split pins etc, this was just to illustrate the most basic function. thank you for adding that as well as many who read comments appreciate the technical data as well.

[@-oiiio-3993]

@@takingbackmejlk No problem. I run a hopped up 225 Odd Firer in a flatfendered Willys Jeep. It's the perfect engine for them.

[@kylehollandsworth4975]

Cant thank you enough for this video!!! Ordered an HEI for my 70 cj5 with the dauntless v6 oddfire. I watched your whole video before my new distributor showed up, very informative! Just installed my new HEI , fires right up and the jeep has never run this well. If not for your video I'd probably still be fighting the timing. Thanks again!

I just got a 225 dauntless. But will need work. So this will help.

[@e.zebdeal18]

Thanks for the video. Solved all the motor problems with my 69 CJ-5. My mechanic had placed the electronic distributor in completely wrong. It would run but horribly especially under a load and backfire, smoke etc. Even when I bought it the plug wires weren't in the correct order with the old distributer. This is probably the best it has run in 15 years. Thanks again!

[@takingbackmejlk]

No problem! Yes they actually run pretty smooth, there is a common misconception that the odd fire engines run "rough" because of the odd fire timing but I found this was only the case because no one knew how to set them up properly, I didn't know how either for 6yrs of owning one I was tired of the engine running like crap so I set out to figure out the timing and now we have this vid. Stoked to hear it's running how it should!!

[@carlbouthillette198]

Jason, thanks for doing this. Someone had replaced the distributor cap in my '68 Jeepster and put in a wrong one. I was having trouble getting it to run right and now I know why!

[@takingbackmejlk]

Thank you for commenting, let me know how it goes and if everything works out, you will be surprised how smooth these actually run, I see videos online of guys always saying that the odd fire just runs rough like that so I send them my video so they can hopefully fix it before blowing the engine like I did on my first rebuild 6yrs prior to knowing this. If you have any questions or need to trouble shoot I might be able to help you pin point any issues. Thanks again!

[@The_Future_isnt_so_Bright]

It is truly amazing that this was even attempted by any manufacturer. Even today the Dodge Viper is an odd fire V10. Gm had several engines like the 3.3 v6 that had offset crank pins but was still odd fire somehow. Thank you for the video . People don't know that these ever existed and is difficult to explain without a visual aid.

[@-oiiio-3993]

It was the crankset of a the aluminum 90 degree 215 inch V8 shortened by two, which meant that the ignition timing would be 90 - 150 - 90 - 150 - 90 - 150 rather than the 120 - 120 - 120 -... 'even fire' timing of a 90 degree V8 as opposing cylinders were still paired on the three journal shaft. In 1977 GM 'split' and offset the paired crankshaft lobes to allow all six cylinders to fire at 120 degrees rotation for 'even fire'. Some 'even fire' 225 engines were built before displacement increased to 231, later rebranded as 3.8 Liter.

[@gillesdouaire6616]

Very cool. I had always wondered on the unequal tabs length under the distributor. Now I see why they are that way. Thanks!

[@jeffsadezwicz7349]

Thank you very much I am rebuilding my boat engine and was wondering the correct timing method I knew it had to be a certain way because how it fires even and odd

[@takingbackmejlk]

Hope it helps! Thanks for commenting!

[@tcast44]

Super informational! Thank you. It makes so much more sense when it’s all drawn out. Seems a lot less complicated than people make it out to be. Can’t wait to see part 2

[@takingbackmejlk]

Part 2 was a vid I had up on just how to install a distributor, any distributor really. I may post it again later but the recording quality was poor so I was going to redo it. Thanks again for commenting, it always helps to get feedback.

[@tcast44]

Copy that. I’m getting ready to install an HEI on my dauntless. I’m hoping it goes well. I might have to shoot you a message for a little guidance if I start having trouble.

[@takingbackmejlk]

@@tcast44Thats fine. You can hit me up. I might just post it for you to reference. Probably tomorrow or in the next couple of day. I will send you a notification that I posted it with a link.

[@chrispompano]

Well, here's the "Oddest" question of all! I wonder if this odd fire distributor, can be adapted to run another OddFire 90 degree V6 that's foreign & has the same firing order of 90/150 ect......

[@takingbackmejlk]

It would have to have the same setup and the same timing cover as well as the camshaft with the same exact helical gear that will mate with the helical gear on the bottom of the distributor, as a comparison a lot of even fire distributors go in vertical however the odd fire distributor goes in at a bias angle into the timing cover with a helical gear. Experiment at your own risk because as you know engine parts need to be precise to the thousandth of inch, anything off can cause a complete catastrophe within the engine especially if they do not mate properly. You might try looking online to see if there is a compatible HEI distributor for the engine you are looking to use it on otherwise for liability reasons I have to recommend not to try it.

[@chrispompano]

@@takingbackmejlk Thanks. Probably DUI Distributors would be the only one to make it work.

[@jesusvasquez3203]

Awesome video!!!!

[@takingbackmejlk]

Thanks!!

[@antoniolopeznavarro8343]

@@takingbackmejlk where we can find this distribuitor or minimum the reluctor?

[@luism2959]

Should the distributor rotor point to #1 cylinder on the buick engine or point at #1 on distributor cap ?

[@takingbackmejlk]

Thank you for commenting, yes at the #1 cap terminal and wire as shown in the video. I know there are some pics online that counter what I'm saying but it's at the #1 terminal.

[@rgmoffat2072]

Good job, the only correction I’d add is that your illustration of moving the cap is flawed, remember the cap is keyed to the distributor so it only goes on one direction. Therefore, you can move the plug wires as long as you are on the odd “O” cylinder (1,3,5). I know you said you tested it, but they run fine as long as the odd cylinder wires are connected to the ones you have labeled as “O”. Mine has number 1 plugged in where yours is marked as 5.

[@takingbackmejlk]

funny story is I actually originally ground off the key on the underside of the cap to purposely place the cap how I wanted because I was having such a hard time getting it to run right when I very first got my 231 v6, originally I did not know or understand anything about the timing of an odd fire engine for 6 years of having my car that had an odd fire in it, I just put that reference in there because looking at all the pics and research I did online over the years it looked like other people had done the same thing I did by way of grinding off the key tab under the cap to face their caps how they wanted, I could tell this because of the vacuum advance and the way the cap was facing in relation to the vacuum advance, the vacuum advance and the cap could not be faced the way it was in some of the pics that are online without modifying and grinding off the key that is under the cap so I just referenced it to prove to anyone who else did the same thing that it was wrong to do so and to face it like how you were saying and that is "the original way that cap was designed" as I stated this after explaining that in the vid but yes most people won't relate to that particular issue or understand why I mentioned it unless they themselves modified their cap like I did originally. ( reference vid time 15:06 I show and explain briefly that I originally ground off the tab and this was way before I had any idea of the timing of an odd fire and way before I ever made the video, the flaw was that I did this to the cap originally in the first place ( 6yrs previous to this video ) to try and remedy the missfiring.

[@betojimenez4199]

My distributor gots 4 points instead of 3 do I just line those up ?

[@takingbackmejlk]

Sounds like you have the points system, this video is just for odd fire HEI distributors as depicted. The older odd fires I think had the point system distributors, I am not as familiar with those distributors, unfortunately I can not recommend what to do for your set up. However if you have a 225 dauntless I believe you can convert over to the HEI and then just follow this video. I have a second video on how to install the distributor correctly if you look on my channel. Thanks for inquiring.
