OK, just saw your response to my post.

400ml in 10 sec is 2.4 liters in one minute, or between 2 and 2.5 qts, or about .625gal/min. I think that's adequate delivery. Didn't do all the math to check, tho. If you assume 3mpg at wot at 60mph, you only need 1/3 gallon/min...

On a cold start, you should smell slight gas smell at tailpipe from cold start enrichment. Strong gassy smell indicates cylinder misfire or leaking injector.

Just out of curiosity, did you time the motor atdc or btdc? And is the idle you achieve smooth, or does it misfire?

What you have sounds like a timing problem. I have goofed and set the timing at atdc instead of btdc, and it acted just as you describe. Timing will be very late in that case, with the spark real late, with the piston on the way down, and max cylinder pressure will occur long after the optimum crank angle. With a clockwise engine rotation, the crank mark will not be to the timing tag tdc mark by the timing degree amount. IOW, the crank tdc mark will be left of the tag tdc mark by what, 15 degrees?

If the idle is smooth (even tho weak), I do not think you dinged the valves. An easier test than a compression test is to use a vac gauge, attached to an intake mani vac port with a tee and short piece of hose. With the ignition off, crank the motor with a remote start button or asst with a screwdriver or alligator jumper wire shorting from 12v feed to starter (fat cable) to solenoid connector. The engine should turn over slowly enough to see the vac pulse from each cylinder on the gauge. Equal pulses = sound compression. Unequal pulses = mech compression problems.

I know, you said the timing was spot on. Check it anyway. One of the most important parts of diagnosing problems is checking what you are "sure" of. Been there and have the tshirt...
