I have 172 engine and the book call for autolite al7t which is a old number does anyone have a cross reference number. Thanks Billy
 
ditto on the 437's

i switched temporarilly to the al7c that NH sold me.. and they seem to foul as fast as a champion H10, H12 (512) or autolite 216.. so I'm back to autolite 437

What about e-ignition? Had that written down somewhere, but lost it. On 801. Then pytronix has coil with internal resister. Soundguy said NO. Did you check this out Soundguy as you said once that you did not beleive there was such a thing
