Since I turned my engine N/S from E/W the carb starves momentarily on right hand corners.
I think this is to do with the fact the float chamber is long and narrow so can't cope with the amount of fuel required on sharp right handers.
My first step was to increase the needle-jet so it refreshes faster but that hasn't worked completely.
Does anyone have any suggestions please as to how to overcome this problem?
I was thinking that maybe it's possible to baffle the float chamber internally (if space allows) so it reduces the surge when cornering.
BTW it uses a high pressure pump as standard so that's not an option.
Thanks in anticipation.

Could you "adjust" the inlet manifold to increase the angle of the carbs? In effect tipping them up? So more fuel stays at the right end?

?

can't say I've ever seen any problems with carbs at high bank angles, even in the landys etc more likely to be the fuel tank pickup sucking in air.

If it is the carb as opposed to Whippy's suggestion or anything else, how about fitting a small piece of fuel tank baffling foam.

Fozzy has it in her tank.

That might be easier than fitting solid baffles etc.

HTH,

fundamental question - but are your float heights ok?

If the level is low in the float chamber, you could get starvation under load/cornering.

Thanks for the replies, guys.

Reckon the tank foam and/or angling the carb sounds worth a look.
Good thought about float height but reckon it's OK - at least according to the info I've found on-line.

Thanks, Fozzie. I'll look at tank end once all carb issues resolved ATB Pewe

I think, I would look more toward the fuel tank side of things first.

Firstly, is your pick-up pipe located low and to the side?
If it is a bit short on the inside of the tank, this could be your problem.

I do not think your problem is carb end

So.....As James rightly said, I have 'foam' in my tank.
Stops corner 'surge' and 'starvation'......

I fitted it when I made my tank....so you do need access.

I just googled this.....(I don't know the company) .... tank foam linky

HTH Fozzie

Edited to add..... I would advise getting the intermittent 'starvation' problem sorted as soon as possible, as it could potentially damage your engine ....

i have this problem in left hand corners-
R1 CARBS on the right hand side of the engine (zetec).

I am pretty sure its not the tank end as I have fitted a swirl pot set up. I have increased the angle of the carbs, but have to wait for the next track day to try it
(cant reproduce it on the road)

would be v interested if you find a solution. how would I check the float levels?
