That will take a little extra tuning...


I bolted a BLP 3 circuit 1000 to my pump gas 505.....it was borrowed from a local dyno guy I know. So, I didn't want to monkey with it too much.

However, it fouled out my plugs in less than 1/2 of idling and one short drive.

I'm sure the 3 circuit can work on the street......but like Greg said.....plan on tuning time and prob a set of plugs

My BLP main body came with the third circuit plugged. I can't tell from the photos if the carb the OP is looking at has plugs or bleeds in it.

Why would a roundy round carb need the third circuit?
