AIR INTO CARB/INLET RUBBER?

[jon the gripper]

my zed is hanging on at low revs? it was running fine then out of nowhere like a lump of shit,checked all rubbers found a tiny split in one so replaced it with new,reassembled and it was better,but still more like a 500 than my zed 1075,more fiddling trying to get as good as seal as poss,slightly better again,rev up to 8000,but still not crisp and as it was,is there a sealent that i can use on rubber_carb to add extra seal as i am sure this is the root of my problem and on disassemble there was a jelly like substance in rubbers,help!!

Have you had the carbs apart ?...

[Steve Cooke]

If the clamps are in good order and on new rubbers you shouldn't need anything else to achieve an effective seal, also there is a good chance that some of that jelly like substance you speak of has now worked it's way into the carbs, sounds like a good clean is in order.

Wot Mr Crook... errr Cooke said, and if rubbers are cracked you MUST get new ones, don't risk a holed piston

HAD CARBS APART,FLOATS ALL OK,MAIN JETS UNBLOCKED,BUT WERE CLEAR ANYWAY,ALL THROTTLES FINE AND IN TANDEM,NEXT JOB IS DRAIN FUEL AND REFILL WITH NEW,HOPE ITS ROPY PETROL!

petrol only last a few months, you can often tell because it smells like vinegar, dont put it on your chips though. I had a race bike a few years ago that wouldnt run right on the dyno, seem very flat, petrol was only about 3 months old, put new in it and it was perfect.
