Racing Fuel Systems

I didn’t notice there was these changes to this new forum so it’s also posted over there sorry.
The price is attractive on this series carb and wanted to know if anyone here has used one or done any tuning to one. This will be for a hot street car.. Carb # BR67277...Thanks guys

They need the same as any Quick Fuel. Lowered idle feed restrictions, t-slot restrictions, recalibrated main and emulsion.

So far this is my experience with Brawler.
Brawler 570

Mark, can you give me a starting point on the T-slot,IJ,MAB,IAB. Also the E bleed size and plug the middle?

Thanks

you might want to check with Nick_nl. He has one of these in Europe and had substantial trouble with it.

If it doesn't need a choke look at the Holley Street HP 650. For the Brawler if you must .081 t-slot restriction, may need smaller, .028 idle feed, .070 IAB, .028 MAB to start.

Thanks Mark, And yes it needs a choke so It seems like you are not a fan of the Brawler series so what would you recommend?

Holley Street HP, the baseplates have smaller transtion slots. Still would suggest threading the lower idle feed position to make it adjustable.

Mark,
The street HP carbs I see online do not have a choke. Any thing like this with a manual choke?

Can you put a holley street hp baseplate on the brawler? Then you would have the choke.
