火箭三R中气缸压缩为零。有人知道原因吗？

what ever you do don't worry abut the decompression system. lol
he said "However, when I open the throttle, it stalls."
to me this means it has a big vacuum leak in the hoses or a bad map.
what i have seen on burnt valve or a worn down cam lobe that it works bad at idle then when when revving it does not fall flat on its face. mostly just reduced power.

It doesn't shut down when you open the throttle, but sometimes it shuts down by itself.

I spent a lot of effort removing the outer casing today. I wish my fingers were as thin as chopsticks; the space is **** tight. I measured the valve clearance on the leaky side and it's 0.58. The pressure reducing valve moves freely without any sticking.

I think I made a mistake in the measurement. I measured the clearance when the pressure reducing valve was working. This caused the valve to have clearance. That's why I measured 0.58. If I open the pressure reducing valve and put it in a non-working state, I try to insert a ruler with a thickness of 0.02. It can't be inserted. Because there is no clearance, the valve cannot be fully reset, leaving it in a leaking state.
