How I picked up 150 horsepower for $5...or the secret governor kids won't get!!!
I just bought this nice little 71 swb 4x4 pu: 350/350, QJET, 3:07s, skinny tires, dual exh and runs great...but, it wouldn't go over 65 mph-top speed.
It was not driven much so: 1. I changed the carb filter (lots of rust & dirt). That didn't do it. ![]() 2. I checked the lines into & the pickup tube size. Ah ha---small 5/16 six cyl lines had been used to change the tank...but wait, there's more! ![]() 3. Look at the filter added to the bottom of the pickup tube, inside the tank, where the sock would be. I am sure it seemed like a good idea to someone at one time...but, notice the size of the openings in & out on the filter. They are just UNDER 3/16"!!!! They didn't even trim the openings up to the next stepped size. That wouldn't feed a lawn mower. ![]() I may try that filter idea if I can get one in 3/8". You never know what the PO did and boy can it be a surprise...and I thought I had seen it all. ![]() |

It takes all kinds! I'd never have thought of that as a filter location. Interesting.

My friend's truck had 7 fuel filters between the tank and the carb....what'll they think of next?
BTW, when he removed all but one the truck got better mileage and ran like a scalded dog.

That truck forgot what it was like to swallow.Been sippin`for years,I bet.
Dirt can clog fuel lines.Filters prevent this...unless they are the clog! ![]() ![]()

Hey that would be a great ideal to use a filter like that on a teenager car or truck.

Wow. His intentions were good but he didn't know it could be starving the engine.
If one wants to put a limiter on how fast one runs, say for a kid driver all you have to do is install a thin plate under the carb with holes half the size of the carb. It's called a restrictor plate. It does work, look at Nascar. My dad once bought a stock Elcamino that wouldn't run more than 60 mph. The previous owner had a restrictor plate put under the carb for that very reason and it sure worked. A piece of thin sheetmetal is all it is. ![]()

How does it run now? Bet it'll beat the 65 mph now.
