My newly restored M38A1 now will not start (except with starter fluid) when cold or after it has been sitting for two or more hours. It starts fine if it has been run within the last hour or so and it runs great with plenty of power and acceleration once it does start. I checked the vacuum at the base of the carburetor and it reads 23. Timing is good. I thought maybe the fuel pump is weak and is not pumping fuel up to the carburetor after it sits a while but it runs good and smooth with plenty of acceleration and power. It has me really stumped. Any ideas out there?
