so after buying a set of refurbed HIF 6 carbs which wernt cheap, paying a clown to fit them and tune them ,and then another garage(2) to tune them they were fine for 50 miles, they then went off balance a bit and needed the choke out a just a little to stop low idle-stalling when very hot.
then one float stuck so I ended up taking it off my self, sending it back to be fixed under geuarnetee and then re-fitting it my self. when went well and I was back to it running well and just needing a little choke when hot (I know obviously that that isnt right lol)
So garage(2) said ok we will have it back for another tune up foc as it still wasnt right, I saw an oppertunity to learn a bit here with no concequences and try to tune it my self as I have two times colourtunes and a balencer but am not of the carb generation.
so ran it up to temp on a 10 mile trip so the oil temp was right up and all how it should be , found one carb was pulling 17 and the other 29 , so rebalnced them after being very very thouroughly cooked with under bonnet heat in the garage , boy do those stianless headers kick out some heat. anyway did it properly , link bar off , revving it between each adjustment and letting it settle etc, adjusting the link bar before clipping it back and I would say they were darn perfect!
switched off to set up the colourtunes whioch I did with a few minor burns lol , ran it up with them in and it didnt sound right, plus the colour looked lean but the plug I took out looked very slightly rich ?????? I dont like the colourtunes now
anyway I thought it may have been rought because they were in so I didnt make any adjustments , just put the real plugs back in and it still ran crappy, few back fires after a rev and wont idle without choke again.
so can anyone tell me why after getting it spot on , just turning it off and swapping plugs in and out and then turning it back on again would make it run like crap?
I am getting very fed up here! :shock:
