Have got it nearly all sorted out, so use to working under hood to tune etc, doing on a lap top now SO different..........thanks so much for the offer to help. does have multiport Sportsman along with FAST distributor. Now using a pertronix ign box, as I thought the FAST was faulty, No it wasn't I was the fault :-) FAST checked, no charge even for shipping back it was not at fault, so kudos for the no charge :-)
