Just when I’m thinking Montina is running good she pulls a fast one on me. These old 40’s are definitely temperamental sometimes.
I’m trying to figure out a significant lurching that has now started. It feels like a drivetrain issue in first and second gear. She idles fine but when going slow speeds she feels like there’s lurching off and on. I adjusted the points gap and fine tuned the carb adjustments to the best vacuum reading but it’s low at 12-14. I’ve had it as much as 17 previously but it won’t go above 14 now.
I put an oem see through fuel filter and notice the fuel gets low in the filter when running and the fuel pulses visibly in the filter. Is that normal for it to pulse or maybe my newer puel pump is bad?
I’m pulling my hair out after trying everything. Timing is good with the ball right below the indicator. Anyone know what I’m missing? Thanks for any advice.

Cold nights warm days - water will condense out of the air as your tanks breathes (same for the store tank); add a yellow bottle of fuel dryer every so often. The paper element will hardly pass gasolene when it gets saturated with water. Put on a fresh one, set the old one in the sun for a few days, it will dry out and you can use it again.
Use a can of wd-40 with the pee tube to lightly and quickly spray the intake manifold gasket mating surface on the engine when idling. The rpm's will kick up at the leaky spot. Do the carb base and section seams. Put a big hemostat on the vacuum booster hose - does the vac meter go up?

You can wire in and plumb in a low pressure $10 booster electric fuel pump from Amoron/Ebay to see if its a fuel pump issue.

Changed fuel filter, still lurching. Tried spraying around carb and manifold and no surge. I’ll get an inline pump so I can rule out the oem fuel pump.
I may try the original carb again. I’ve had a cityracer carb on it for a while with ok results.

After a couple of frustrating days I think I worked out the lurching at load problem.
I readjusted the points and went with a snug .012 gap and seems to run happy. In the process I must have worked the distributor retard function loose and now it moves with vacuum. I had to cap the nipple on it otherwise it retarded the timing too much and shut the engine off. I am desmogged so probably need an advance distributor instead.
In the process I adjusted the valves again. I cleaned and regapped the plugs. They were a bit too small. I Got the choke cable working and adjusted the carb. I still don’t have great vacuum but it did come up to 15 from 13. I also blew out the metal fuel lines from the tank. After getting it running steady I put the air cleaner back on and started to tighten then it bogged and cut off. Restart and won’t start. I pulled the cap off the top pipe on the air cleaner and it ran good, put the cap on and it bogged down. It must have been a clogged air filter. I’ll order a new one and see if it helps but the old one didn’t look that dirty. I blew it out and it was still too restrictive.
So a clogged air filter seems to be the main culprit.

Finally had a breakthrough moment with Montina! Running problems have been diagnosed and fixed after almost a year of head scratching and random running issues.
Turns out I had the carburetor cutoff solenoid plugged into the wrong plug from the harness. When I switched from the OG carb to the city racer carb I just assumed that the square plug went into the square female plug. I was wrong. I tested the volts from that plug switched on and it read 8-9 volts. There was another round plug next to it on the harness that I thought was a sensor plug that wasn’t there. I tested that one and got 12 volts. So I took a male plug from the OG carb and spliced it to the fuji carb that came with the square and plugged into the round female plug. All of a sudden idle came up, idled smooth and the vacuum went from 14 to 17. What a difference and the idle screw actually was responding to adjustment. So that was the underlying problem the whole time.
Now vacuum is strong, idle is steady, more power, and it responds to adjustment now.

They could definitely do jungle training down here. The vines have taken over the china berries and choking the cherry laurels. My poor tractor has been put to the limits on this project.Reminds me of the Land Nav course at Ft Benning…

The Kudzu was really bad. It never sleeps.
The southern flora and fauna will defiantly tax your “equipment”. Are you clearing to build or cultivate? Looks great!!!

I’m clearing an area that was over grown for the last twenty years so I can put up more fencing. My flock has grown and needs more grazing area. These vines are muscadine grapes mainly with some bamboo vine. These bamboo vines have some really narly thorns and will regrow if you don’t dig up the potatoe size roots. I use a root rake to do the clearing, stacking and burning.
