On ther web side it said 120 low 145 high 95g spring but alot off other Places they use 135 high soo what is it ???

 

[tor*p*do]

120/145 is for single carb 61x application (pre '96)
70/135 is for dual carbs in 62T application ('96+)
both are listed on FPP website under corresponding install instructions

I'm running 135/75 with 53 pop and I have a lean hesitation at 1/4. Stock airbox I think I need to drop my popoff some. 135/70 may be okay on a stock boat with a pipe but with high compression and other mods, might need a bit richer on the pilot. 95grm spring would give pop about 42 so that's probably a good spec.
