just been out for the first time on my Montesa,had a great time,but had problems with the carb,i'd already cleaned and blew all the jets through and treated it to a new filter and throttle cable,
the problem was that if you lent the bike to either side the revs went up and wouldnt settle down again,the cable wasnt trapped,the throttle wasnt returning straight away but the slide was,could it be the float level or the needle not shutting off.
the carb wasnt overflowing,if you opened the throttle past quarter open the revs would increase on their own,got to be a carb issue of sorts,but what ?,we would like to go out again on sunday,so i got to sort it cheers andy
