Thread: 2.25 head failure

I only have to use choke now if is been sitting a few days. pumping the throttle didn't work. the engine wont fire if you hold open the throttle.


the original system works-you have to hold the throttle at half then pull out the knob as it wont come out due to the fast idle ramp.-once it has crank over and fires up ,stumbles a bit then revs up because the fast idle step is about 1200 rpm, the choke flap is pulled open and flicks off the choke cable.


To use the choke to warm up the engine you had to hold the knob at half way out as it would stall or flood. I cant pull out the choke once its running.


In the morning I put the hand throttle on the first notch. few months ago it was on the second. I have 2 intersections near the house, If I have to give way it would back fire when I pulled out the clutch [flat spot]. I don't need any if its in low range.


with ignition advanced it doesn't flat spot. im running manifold vac with a slight restriction on the dist advance. Datsun 200B port.
