Bike Carb Problems

[Guest coops222]

hi guys,

 

got some bike carbs fitted to my 2ltr pinto, it will start and tick over (although very lumpy) and as soon as i press the accelerator it cuts out...

 

has anyone got any ideas?

 

cheers paul

Have the main jets been changes to suit the car engine? If not that's your problem.

Is it a new fitment or have they been on for a while and this is a new problem.

[Guest coops222]

Its a new fitment.. bought them off someone who bought em off someone else, don't know about the jets, how can you tell? And can you buy the sets?

could be the needle in the float chamber sticking,clean them with plenty of carb cleaner.

get the car to a dyno you cannot just fit them and expect them to run. there are a multitude of settings to get right

Bike carbs often have a choke

Usually a slide arrangments operated with a cable from the rear left of the carb set

Sounds like your getting it to fire but not warming up with choke

 

What carbs are they?

you could spend ages trying to get it right get a dyno check and they will fix your problem and save all the hassle and time

Thanks for that.... sounds a bit technical for me. Just found out bogg brothers aint far from me, so I think a trip there is in order....

I went to Bogg brothers last year on the way to Newark the old boy knows what he's doing he will drill out the main jets to the right size and balance them for you think it cost me £80

two things, pull the choke on will it rev?

 

as a general rule, with a mild cam you could drill the main jets to 150 (1.5mm) drill bit then try again, it will still need to go on the dyno to sort the dizzy timing unless you have a timing light and they will need to balanced.

 

done a couple and this got me to the rollers ok

 

Hope this helps,
