I have a 1998 srx 700 that only runs on 2 cylnders. I have checked compression all at 115 psi. spark is good, reed valves are good,powervalves are good. it has new gas spark plugs and wiring, and carbs are clean. pto side gets gas and spark but will not fire. any ideas

pull all the plugs and pull it over as fast as you can, that cyclinder could be flooded with gas if you have a needle and seat stuck open.
i made sure everything was dry and it still wont fire

1.) is there fuel in the pipe?
2.) when you had the reed block out, is the skirt intact on the piston?
3.)did you check the sparkplug boot on that cylinder for resistance?

had a buddy with a triple that wouldnt fire on pto cylinder. swapped coils, checked compression, carbs, whole nine yards. ended up being the crank seal was leaking so bad it wouldnt fire..... had the seal and bearing replaced and good as new.
if i pull all spark plug wires and put pto wire on only it will run on that cylnder but not as good as if i do it to middle or pto
Check crank seal. We used to blow smoke into vent to see if it came out seal. (if you have vent on that cylinder)

try the good old fashion ether small quik spray an if its leakin she will wind up
make sure the crank seal is good ...............
i just got done with the motor new rings and crank seals. also went through the carbs again it is still doing the same thing.
did you try swapping the coils . Sounds like you got a weak one
u can try to mix the coil on a 98 srx they all fired at sme time
