feetupfun Posted July 6, 2004 Report Share Posted July 6, 2004 Rockhopper You have good taste in bikes. 348 Cota timing is 1.8mm BTDC or 17.5 degrees BTDC Ignition points gap 0.4 mm Sparkplug gap 0.5 to 0.6 mm Sparkplug NGK BP5ES or Champion N12Y Cota 348 comes standard with MKII AMAL concentric (square body round slide AMAL same as what came on Bultacos of the same era) AMAL model 2626/402 Some people fitted a Dell Orto carby to replace the AMAL on the 348. My 348 goes great with the standard AMAL carby with standard jetting. AMALs tend to wear out needle jets and needles quite quickly but parts are usually readily available. New AMAL and MIKUNI carbies are available for the 348. David Lahey Australia Quote Link to comment Share on other sites More sharing options...
