François,
I have added one-way valve after fuel filter. It didnot help at all. So I don't believe it is fuel pump issue.
Also carb accelerator pump gives strong squirt of fuel even cold so there is fuel in carb.
Albeit symptoms are same as yours. Please tell me if you find a solution..
What advice should I follow? I have tested compression, fuel squirt, coil voltage, ballast resistor, battery voltage
Manual says that DO NOT press gas pedal before cold start. However, I have tried all methods:
- Not touch gas pedal at all
- Give it light press to engage choke
- Pump it few times before start
Not any of those methods work. Choke closes fully and also high idle cam seems to work.
Giving a little pilot spray and engine starts right away, so my main suspect goes to carb, but all I can consider is give it ultrasound wash and put repair set to it or replace whole carb. But there seems not to be direct swap carbs available so it is a project also.
It is difficult to take video from engine/carb and start car same time. I mostly start it alone so there is no help available.
It also takes two days or more to this problem arise again so not much possibilities to diagnose or take videos.
