Firing order needed?

Ok blow air with compressor or mouth. Never heard that one but will try. Just put a hose into the hole and if u can blow air its not tdc. Right

I changed my plugs, but I may have gotten them out of order. I tried to pull one and replace one, but I had taken off two, before I decided to go one by one. I just want to make sure they are in the right order.

Ok its a 305. When I pulled the distribuator out I did not have it on tdc. Then I found tdc put dist. Back in with rotor pointing at no1. Still nothing. Then changed coil, nothing then replaced module, nothing. All it dose is turn over and puffs out of the carb. Could it b out by 180?

I just put the line on the balacer in the middle of the marks then check with a srudriver but feels like there is still a small gap on top of piston. Is this wrong

Ok I see.I, ll try that finger over the hole trick. Thanks for the info.
