Finally got to the bottom of the fluctuating temp. Gauge would go from 160 to 230f and back constantly. Would never spit coolant out but something wasn’t right. Eventually gave up trying to figure out what it was an decided to through some parts at it. First thing was to change the thermostat. It’d got a high flow one with bypass holes in it. It was new when I built the engine and I’d tested it previously. So I got on old one that had been lying at the bottom of the parts tub for years, tested it, drilled 4 bypass holes in it and stuck it in. What do you know cooling is now perfect, maybe too many bypass holes as it sits about 160-170f but working fine. I can’t explain why change from the one pictured below to a normal type makes a difference unless it was causing some sort of air/steam lock being a different shape.

High flow one that was in there:

Can’t get to the bottom of stalling under heavy braking. There’s a lot of fuel around the carb mouth, but it’s not coming out the float vents so I can only assume it’s coming out the air bleeds. Fuel level is below the sight plug so not sure what to do now.

Have had a fiddle with float levels so the primary is just above the sight level and the secondary is now 1/8” below the sight and it seems ok now. I’m going to try raising the secondary a flat at a time to see if there’s a point at which it stalls again. For those not familiar with Holley carbs the float chambers are at the front and back hence trying the different levels.

Moved forward with the exhaust so the fabrication place is going to build a system that runs down the side and then ticks in front of the rear wheels and then out the back to get some bigger silencers in. They’re also going to take the cost of the first effort off this one. So fingers cry for more power and less noise. This sort of idea

Made up some vapour barriers for the doors as the door cards are getting damp.

Sealed some bolts in the scuttle as they were leaking water in to the footwell and tried some stickers out for size. Not convinced yet.
