This afternoon I’ve tried with the clamp of the carburetor’s needles in the lowest position (needle at highest position) and that runs. Runs good, even! The "dip" that was yesterday between 2.000 and 2.500 rpm is gone and the engine pulls over the whole range. After checking the oil level, it was above max. so I took some out.
The engine runs and idles fine. We should be all set for the moment 🙂
Cette après-midi j’ai essayĂ© de mettre les petits pinces des aiguilles dans les carburateurs sur la position la plus basse (l’aiguille au plus haute) et ça roule. Du tonnère mĂŞme ! Le "trou" d’hier entre 2.000 et 2.500 rpm a disparu et le moteur rĂ©pond bien dans toutes les regimes. Après vĂ©rification du niveau d’huile , le niveau Ă©tait au dessus de max. donc j’ai siphonnĂ© un peu.
Le moteur tourne bien et tourne bien au ralenti. Ça devrait le faire pour l’instant 🙂
Vanmiddag heb ik geprobeerd met de klemmetjes van de naalden in de carburateurs op de laagste positie (naalden in de hoogste positie) en dat loopt goed. Loopt heel goed zelfs! De "dip" die gisteren tussen de 2.000 en 2.500 rpm zat is verdwenen en de moter trekt nu over het gehele bereik. Nadien het olie peil nog even nagekeken en het stond net boven het maximale dus heb ik er weer wat uit gehaald.
De motor loopt nu goed en loopt goed stationnair. Voorlopig kunnen we weer even vooruit 🙂

  1. HI Rob,you could try setting the carbs up the way i do it on my 69 T120 works really well on the triumph. First adjust the throttle cables from the cable junction so that they have the minimum free play,, Then start the engine & take one plug lead off then adjust the pilot air screw & throttle stop screw in the OPPOSITE carburetter until the motor runs regulary then replace the plug lead & repeat the process similarly for the other carburetter. With both plug leads replaced the idle will be too fast & the stop screws should be lowered simultaneously until correct or the motor will run rough. particulary under accelerating HOPE THIS IS USEFULL STEVE AUSTRALIA

  2. Hi Steve ! How have you been doing ? Thanks for your comments, I can give that a try, I suppose you do that on a warm engine ?

  3. Yes Rob on a warm engine as it is hard to keep the engine running if it is cold, as you say everything is easy when you know how, i ride my Bonny like its stolen and if done regularly it stays in perfect tune and runs great, by the way i love reading your blog.
