• To ALL forum users - As of late I have been getting quite a few private messages with questions about build ups here on the forum, or tech questions about your personal project. While I appreciate the interest, sending me a private message about these topics distracts from, and undermines the purpose of having a forum here. During the day I wear many hats as a small business owner-operator and I work tirelessly to provide the absolute best service possible to you, our valued customer. When I created this forum I rounded up some of the best minds I knew so that any tech question you might have could be asked and answered by either myself or one of my highly experienced moderators, this way the next time this same question is asked the answer can be easily found and utilized by the next IH enthusiast having the same question. This allows me the freedom to run the day to day operations of the business and minimize the impact to shipments and shop activities that these distractions can cause. It is of the up most importance for me to complete the daily tasks in order to best take care of you our customer, all the while providing you a forum to get the level advice and input you have come to expect and deserve from the premier IH shop in the country.

    So with that I ask that anyone with a question about one of our build ups or a general tech question to please use the forum as it was intended. I am absolutely available by telephone to answer your questions as well but at times may direct you back to our website to better field your question or questions. Most other private messages I will be glad to answer for you.

    Thank you for your understanding.

Pertronix Ignitor I II or III?


New member
Confused about all the different Pertronix Ignitor systems. I have a 1973 Scout II 304, which is the best system to use? Same with the Flame Thrower they also have a I II and III.


The Pertonix 1 will die if the ignition is left on without the engine running. You don't have to do it, a guy at America's Tires killed mine. Same guy who said my truck was stupid because he couldn't figure out how to release the emergency brake. He didn't work there for long. There are Pertonix 2s and 3s for a reason - much needed improvements. I went with the DUI, and have never regretted it.


also the III is a multi spark fire like a MSD.

i have had the pertronix I for the past 15 years. no complaints. ill replace it when it dies but it just hasnt yet...
