RE: anybody know the difference?
Mad, based on my experiemce with remote needles they are worth having. Since fuel can neither be stretched nor compressed the mythical delay in responding to needle changes is simply non existent, the HS needle could be in the bottom of the tank and still do its job. In fact this Fitzpatrick .61 had the HS needle sheared off in a crash. I drilled out the HS needle hole and blocked it. I used an MDS remote needle which on other engines stands up to the tank pressure on a Cline regulator system. I have an ASP 1.08, it has what I think is a huge carb but the carb works really well.
