RE: Club Laser?
I'm in
1. Laser 70 (circa 1997)
2. Laser V-300 (circa 2001)
Mine are the older "angular" finned versions, not the later "rounded" look. They have the Irvine carbs though.
IMO Laser are the world's best quality four strokes. I've owned all major makes (except HP and Webra) of model four strokes and loved them all.
But Laser are special.
Mine run fine on nil nitro fuel (yep) and any warm rated plug (K&B 1L, Fireball yellow for example). I have found no improvement in idling or throttling with OS "F" or Fox "Miracle" plugs. My findings mirror Neil Tidey's advice as found in the instruction sheets with the engines.
I am currently using OPS RC 250 plugs in my Lasers (real nice plugs - are OPS plugs still made?) but ENYA No 3's also work very well.
