I need some help in finding out the carb needle settings for a L. Collari WRXLC21B3 engine. Thanks

Get an OS or a NOVA carb, you will not get many supporters of the collari carb, it has very fine threads and many find it a beyatch to tune.

i had issue with one of my b3 carbs, in the end i put a b7 carb on and had no problems, ask the question on the forums to see if someone is willing to sell a carb off an expired engine

Most of the guys I know are running the Nova or RB carbs, including myself!

The newer carbs on the B3 are much better though. The ones you have to watch out for are the ones with the brass slide. If you have one that looks like it has been hard coated (dark grey) then you should be fine.

Thanks for all the info

On mine, the bottom end is set at 3 3/4 turns from being bottomed out. Top end is at 5 1/2 turns out, and the idle opening is about .75mm. This is a final setting using Werks Race Blend 30% and and an 086 pipe. Your settings will vary. Check the tips and tuning section under the FAQ on www.werksracing.com

The fine threads make the carb seem less touchy to tune. When I tuned the B3 in Jason's buggy, I thought the engine was quite easy to tune.

Hey guys what carb will be the easiest to tune the NOVA or the OS(wich one do you guys recommend and if there is other carb that will be better than the 2 mentioned before) and what is the best plug to use with the B3 I've had a hard time tunning the 2 needle collari carb!!! Any help will be appreciated

the reason I got rid of the carb was the barrel was sticking open a little and the idle was bad with what ever I set it at. With the ops carb it perred like a kitten at idle.
