which to use on my runner, phbh26bs or phbh28bn(one 4 minor)

i have the choice of either carb to use on my engine (172,cases flowed/matched to barrel, exhaust stub matched to a srt stub on a scorp,180 vario with 13.5s,srt fly,polini belt,green clutch springs,blue polini contra spring,malossi reed block,running pre-mix) but do not know which would be the best and easiest to set up. i know i will have to drill either carb to fit an air feed. if anyone has used or is using any of these on their runner with a kit on could they please give me their views and a rough idea on jetting, needle,atomiser etc. i am unsure as my mate has a box of carbs and there are 2 of the 26's and one has an oil pipe with oil pump attached so unsure if the 26 with this has an air feed as of yet. i only had a couple of minutes to have a scan in the box but there are even a few mikunis in there, but i have heard these are a bit harder to set up. i am hoping someone like minor or any of the tdr lads or someone who has or have used any of these carbs with a bit of sense wil give me some sound advice. many thanks for reading the thread any way and i look forward to reading any replys. gully. p.s. i was running a koso carb until some f**ker knicked it last week,alive and getting a kicking if i find out who

 

surely someone out there must have a bit of sound advice on these two carbs and the best to use. i just dont want that splutter/flat spot on take off that i hear and have read on the site that the 28 gives. i have looked through 52 pages on the search engine on the site after writing in 28 dellorto and then 26 dellorto. i can only see the 26 dellorto mentioned twice on the whole 52 pages. surely someone must have tried one of them out

 

i know im not minor. but...im running a rs 28mm atm, drilled out.. 108 main moved the needle clip and mixture screw and everything else is the same as it was when i got it, it runs suprisingly well no spluttering or anything.. better that the 25mm i was running before.

 

thanks minor , my mate vowns a bike shop and i never thought to ask him if he had any carbs kicking about , well he took me down into the cellar where he has 3 large boxes/crates of single carb units and just from looking on the top of the boxes i found 2 28's and the 26. there maybe a 25 in there yet but thought if not i would find out what also to get when i grab a carb (any carb £20 for future reference if you need help mate,plus post of £5). i will rummage and see wat else is in there and if no 25's go with the 28, but i will take apart any dellortos to see if any smaller pilot jets or thinner needle and grab an L bend for the throttle cable and a flip up choke. i got a mix of weights of rollers so thats no worry. many thanks mate, your a wizard. with what i have learnt off the two replies i am more confident to go and throw the 28 on an get it set up right, i keep on at my mate to get a dyno as he does mot's and know he would make his money back, its a big place an he has bikes for sell etc
