poor quality fuel ?

what symtoms have people had that they can put down to bad fuel ?
Reason i ask is that i`m stumpped at the minute.
P200 was running fine but due for a rebore - decised to get Harry Barlow to tune a top end. put it all together -only other difference was a SIP fast flow fuel tap. Went out to start running in and did 30miles with no issues went on reserve so filled up at the nearest garage which was a supermarket and went home (about 0.5mile). Went back to it the weekend after to do some more miles. It was a t*£t to start, wouldnt tick over, would only run with choke - so i started the usual things - cleaned carb, new plug/lead/cap,new cdi, new stator no difference - started to have a suspicion the clutch side seal had gone so drained the g/box -all seemed okay. Thought stuff it ripped engine out and stripped it - there was nothing wrong the seal so i rebuilt it with all new seals and bearings - fired it up no difference.
went back in garage tonight and done a bit more - agin a pig to start ,cleaned carb, drained g/box oil to check again, blocked the clutch breather up again no difference - however it will now tick over but it is still not as crisp and responsive as would expect and just doesn`t feel/sound right and it occasionally backfires through the carb if the filter is removed
will drain the fuel tomorrow and try some new from a known brand
any thoughts ?
