You guy's are just wonderful, when I have a cardiac problem, I will seek your assistance. Motu works in the trade and his opinions are valid as there are so many situations the shop handles, it's not their pride an joy they are working on. They are just doing what is technically required to meet that particular situation. The internet opinions are sort like a frenzy, some one reads that this worked this time, you don't really need that so they are all really ripping you. F..k me when I was a young upstart I remember fiddling with my norton's points , fu.kin it up big time takin to a shop and saying it just wont start. The shop stripped the carbs and spent quite a bit of effort on them plus a simple set the gaps and timming. The thing never ran betta when I got it back. Wasn't cheap tho, but hell I was back on the road.
