Indiana_Jones Posted April 17, 2012 Share Posted April 17, 2012 Does anyone have one or access to one in Auckland? Edit: On that note if anyone is handy at tuning (SU carb) that'd be sweet too Cheers Quote Link to comment Share on other sites More sharing options...
KKtrips Posted April 17, 2012 Share Posted April 17, 2012 Whats the issue and what size SU? I've spent a lot of time pissing around with SU's Quote Link to comment Share on other sites More sharing options...
mjrstar Posted April 17, 2012 Share Posted April 17, 2012 I have a wideband port in my mini, but found it to be a bit hit and miss compared to tuning an injected car... To the point where I actually acheved better results tuning the SU by feel/ear/sparkplug colour. You really have to sort out the idle mixture (adjustment) and then play with the needle (diameter) to get fuelling at cruise / max rpm with spring weight (inside the dash pot), then work on transient throttle by fiddling with the dash pot oil(i like a pretty heavy oil compared to some suggestions i have seen).

Indiana_Jones Posted April 17, 2012 Author Share Posted April 17, 2012 Cheers for the reply lads, it's a single HS6 (1 3/4"). Used to have a waxstat jet and floating needle, have converted it back to stock with a normal jet (forget the size off the top off my head), a ZH fixed needle and a yellow spring. Centred the jet etc so I think the carb itself is fine, it's just tuning it and a hands on lesson would be great. Regarding the dashpot oil I had tried light oil (3 in 1, sewing machine kinda stuff), but this time I decided to follow the owners handbook and the haynes book of lies and toss in some engine grade oil (20W50).

xsspeed Posted April 17, 2012 Share Posted April 17, 2012 you could talk to the guys at CSL (Carburretor Specialists Ltd I think it stands for) - top of Carlton Gore Rd, think they get props for being GC's Quote Link to comment Share on other sites More sharing options...
