Track racing wheels

Apologies if not in the right forum.

I'm currently out of 7's and got a cheap fiesta grass track car.
Its a fiesta 1.4 with the lean burn head, standard carb, kent cam - which i suspect is the cvh22.

i guess a rolling road would be best but i'm finding that on the oval track i'm getting flat spots coming out of the corners whilst still under 6k revs.
i've checked the oil level and its fine, maybe slightly over the mark, fuel pickup is on the side that would get the "wave" from cornering.

Just wondering what i can do:

Fuel tank baffle
oil sump baffle
smaller tyres (i'm maxing out on straight in 2nd but then 3rd is too much round bends at moment)
LSD but can't find one for "locost" money
alternative gearbox with lsd in it
full engine rebuild with stage 2 and Twins or R1 throttle bodies

I'm not looking to spend loads but just want to be up near a similar front wheel drive car with similar mods.

Any suggestions. (I know my driving will be kak so i'll take a lot of it to be that to start with)

cheers

Rich

You need to have a google on this, with oval racing fuel in the carb also gets pushed up on the outside of the fuel bowl creating issues such as running weak towards the end of the bends causing flat spots.

The fix is to reshape the float, cutting a wedge out on the side where the fuel will build up, then as the fuel builds at that side of the bowl the float stays at the correct level.

As you are locost why not look at investing in some bike carbs?

thanks, i am looking into that but the cost of the manifold puts me off the idea
haven't found a used one either
