starting issues

1987 se50. It sat for a few months after the auto choke solenoid broke. I just replaced it and still not starting up. I have spark, fresh fuel, vacuum at the petcock, cleaned and reoiled the site filter. Battery is good and strong (during trouble shooting jumping off from my truck). Is there diverting I'm missing or have over looked? I'm running out of ideas to check before taking it to the local shop to look at.

Try a new plug regardless. Plugs can fire outside the cylinder but refuse to work when installed. Also open the float bowl drain screw and drain the junk out of the carb, it might have water in there. Pulling the carb is probably a good idea anyway but you may get away with just draining it and leaving the screw open and cranking it over to get fresh fuel to the carb then close the screw.

choke the carb by hand till your hand is getting wet then take off your hand if it has good spark and good compression and a unblocked pipe it will start .If your hand doesnt get wet then you have a fuel issue

I have drained the carb bowl, but i will leave it open while started to double check I'm getting fuel. I also replaced the fuel line thinking it was fouled. I will also try hand choking it.

When it turns over i can feel the pulses coming out of the exhaust and the plug has less than 100 miles on it but I'll grab a new one they are cheap enough to not worry about.

replacing the fuel line was a good call, especially if it was the old braided ones. They can break down inside and get screwy. If everything is somewhat right hand choking will likely get it to start. Good luck :-)

hand choke works but may flood the motor try it with out it first ... if your temp is in the upper 70 open it up a little when trying to starting it....

Looks like maybe a dead plug. Hand choked and was get gas but no sound of ignition within the cylinder. Also will pod filters work on the stock carb? I know they cause issues with cv carbs like what my cb400 runs.

pod filters can work but you will be running lean, so you will have to rejet your carb
2 strokes are finicky with air/fuel ratios; the stock carb runs best with the stock airbox with filter
