Give me a few weeks of drivin the old gal and I'll need some deductin' to Weeds!
Thanks for sharing your tips J'. Oh, I'm not at all happy with the mileage as I first figured it. When I factor in all the things that detract from the mileage with this particular model it really isn’t much of a surprise.
Yep, I’m around 4,000lbs curb weight, the rear springs alone total 14 leafs on each side and the frame front and rear axle are heavier. Your skimpy little 1/2 ton is only coming in at around 3300lbs, probably less since you changed tires and rims.
That extra weight will make a difference, my first car was a 1941 Cadillac 4dr sedan with a tired flathead V8 weighing in at a whapping 4600 lbs, I ran it over the truck scales out on old Rt. 66 back in late ’58. That baby got all of 4 mpg. It was a good thing that I worked in a Sinclair station and gas was only 29c a gallon back then. Also the longest trip I would have made back in those days was over to the Drive-In in Lagrange, and that big old back seat sure came in handy on those hot summer nights! Ahhh, to be young and carefree again!
Anyway back to reality, I’m not putting to many miles on it right now so I was a little premature in my guest’a’mate (spelling?). I was kicking the idea around a while back of making some spare jets to experiment with. I did make cad drawings of them, just haven’t made any up yet. I made up idle mixture needles and a power piston to replace the bad ones in a couple of other carbs that I was playing with. I took a reading on my plugs last weekend after a 30 mile run and I really hate to change anything cuz they’re looking good.
It does seem to run a little rough in the mid range at low throttle settings, seems like it might be running a little rich. I was thinking about playing around with the spring bias on the power piston to see if I could smooth out the mid range any. Ya don’t want to mess to much with the bias spring cuz it’s a delicate balance. I can wind my own springs from wire I got from McMaster so I can always put the original back in if it doesn’t work out.
Gotta go make breakfast and lunch for my “big old wife”, talk at ya later!
