Hey, you guys are killing me, I hope you have that thing running by now....
1) timing is not off, Timing is held with the flywheel key, the flywheel on the pb-210e is not heavy enough to shear or dislodge it.. (the big aluminum fan is the engine's momentum as it passes the compression stroke)
2). if it has spark, it has spark (try a non-resistor plug)... as the chamber compresses, resistance is increased due to the di-electric effect of the dense air .
3) if you have fluid on the plug, you are flooded (flooded very bad) even if you only pulled a few times on the starter cord.
4) I suggest a needle for the carb. ( metering needle) The carb kit you need is a K10-wa&T... The only parts you need to replaced from the kit are the gaskets / diaphrams and needle ( do not pull the welch plugs or screen)
The kit can be purchased from aftermarket places for about $8
5) IT is never the coil or the ignitor, the magneto cdi system on echo and other small products are bullet proof ( they don't work hard enough to fail).
6) Any torn or cracked fuel line should be replaced (the diaphram with the reed valve flappers does all the pumping of fuel into the carb, any brake in the into the line will cause it to suck air, not your problem right now.)
I suggest :1) take the plug out, with a compressor blow any fuel out of the cylinder throught the hole, pull the rope a few times and do this again to clear the crank case of any fuel.
2) use a pair of hemostats on the fuel line next to the carb to pich off the fuel flow.
3) install a good plug (ND BM6A or NGK W20M-U), I have found that some Champion Cj8's and RCj8's dead from the box new, maybe 3 per hundred or so.
If it starts and pops normally after you release the hemostats, try cleaning grit from the carb/ metering needle.
good luck
