Carb Jetting, Brake bleeding - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi all,
I recently replaced the brake fluid and now I can't seem to bleed the system. are there any tricks on this type of truck? Also, on my last car I was able to replace a jet in the carburator with a different aperature and it bumped my gas milage up about 5 MPG, any thoughts on if a similar modification might affect better milage.
thanks,
casey

I can tell you that the following questions will be asked....what year is your truck, drum/drum or disc/drum. 4x4 or 2wd might help.
Specifics on the car that you swapped the jets out on, as well as your truck, gears, trans, engine, current carb CFM would all be helpful in giving you better answers to your questions.
GOOD LUCK and Welcome to the Board!

oh yeah, for brakes, make sure you always start with the pass. rear wheel, move to the drivers rear wheel, pass. front wheel, and then the drivers front wheel when bleeding brakes.....which you might have to do if you got air into the system. If you fully drained the fluid, you might not have properly bench bled the mc or you might have over extended your mc while bleeding them in which case you need a replacement (recently had to do this myself, told its a common problem on older vehicles when you go to bleed the brakes).
as for the carb jetting....I have no idea, carbs are a mystery to me....but there is a thread floating around regarding putting acetone into your tank....but its at your own risk, and I can't remember the amount off hand.
