adjusting float levels.

Post by hughybabes » Sat Dec 17, 2005 3:33 pm

Since the rebuild of the twin carb motor, it has had a flutter/hesitation on right hand turns; more pronounced on an uphill incline. Have replaced dizzy cap, rotor button and plug leads. Have checked for faults in wiring and vacuum hoses.
Saw a post on USMB that said he had a similar problem and found it was the carby float levels. How easy is it to play with these? Do I need to replace a top cover gasket when reassembling?
Thanks,
Steve

Adjusting float levels is painful, gaskets often breakup and are hard to buy on there own. Check the balance first, if thats ok try looking down at the discharge tubes as you slowly open the throttle. If the lelels are the same both tubes will atomise the fuel at the same time.

Um, Hi Steve. do your carbies have little glass sight windows (to check levels) with a dot or line etched to indicate the desired level /

I thought mine did, just crick your neck with a good light while its running if you do got window. Old gaskets usually break up but yours should endure a few on and offs if need be.Then it is trial and (often) error.

If I ever forget why i love LPG other than paying for a tankful, its times like this that brings back memories ! If I had a dry sump and a good stomach the Brumby'd almost drive up walls and along the ceiling - no gravity sensitive fuel sloppin' around the engine bay.

I wonder if for trivia sake, disconnect fuel to the rhs carby for a tick and see how it runs around bends on one carby and then try isolating fuel to rhs only and try again - to isolate which carby is causing problem.

if two heads are better than one, surely two carbies are too when it comes to your problem. in some senses it may not be your carbies either, tell the misus you need the money for a 5 speed conversion - that'll fix your woes !!


merry xmas all
