Thanks Chrales.I have not too much exp with the spray.I've been around the spray.Not ready to blow a whole in one of my stock pistons.Too much spray and timing.Not enough fuel.KA BOOM!!!!!!Nope I will leave that to the spray pros.LOL .Just cant take a chance on killing a good engine.My engine runs too good for me to exp with the spray..That 30 shot may be good to start and learn some spray knowledge.HMMMMM......
