Amazon sell CHINA JUNK.. plz don't support CHINA..
I`ve used proform carbs and had no propbems, I bought 5 proform HEI distributors and 4 of them failed in three months. They all died within 100 laps of one another, the 5th is in the shop and I use it on the run in stand cause I`m afraid to sell it. Your motor sounds good, torque is what you feel when ya push the loud pedal.
Thanks for another great video!!! I loved the comparison and the input from everyone!!!
I have had mixed results with the cheap hei. I think Hei type ignitions are fantastic. I have worked on 3 and owned 2 of the Amazon/ebay Post Covid units with erratic advance curves that couldn’t be tuned out and shafts that snap in the body or non standard hei components and they fail. I have also had dozens of pre covid units that were flawless.
