>>Been having trouble with the my email, stemming from my spring cleaning my
>>computer, new win98 installation outlook not importing old settings.
>>
>>The problems
>>Just fitted my new stock exhaust back box to replace my Swiss cheese old
>>exhaust. Just so you know UK 1500 duel SU's supposed to have 71BHP and do
>>101mph.
>>
>>It's now going as fast as it has in ages, 68mph, although my old shot
carbs
>>would get 81mph.
>>
>>The car now revs to 5200 rpm under load :-)
>>
>>Unfortunately the fixed exhaust has brought to the front my carburation
>>problem.
>>
>>It's completely bizzar!
>>
>>At high speeds (55mph+) easing off then accelerating has bizzar effects.
>>After you have eased off when you accelerate you expect some kick but you
>>dont get any, after that sometimes easing off will cause you to
accelerate.
>>It defies logic. You maybe get a smell of petrol.
>>
>>How much of a problem is warn throttle spindles for full power high revs
>>(2500 and over)?
>>
>>Could this be something to do with the fuel pump.
>>
>>Or my warn engine upper half.
>>
>>The next mail
>>
>>An update here,
>>
>>I have just stripped the right carb and melted onto it some silver solder
>>where the spindle was warn. I then used some wet and dry to bring the
>>profile back to ordinary. I am quite pleased with the results, the
profile
>>is now very smooth, and I have lost 3/4 the play in the spindle. I will
>put
>>this carb back then strip and tin the left carb later tonight.
>>
