1) Don't use choke and throttle ... as it will lean the mixture (the choke is designed to richen the mixture).Only thing different i did and i think that's the mistake i did in winter- is remove the spark and put few oil drops in the cylinder ...
so what is happening when i hit the starter, it goes on and on with no signs of willing to start at all, tried with/without choke, full gas,
2) Take off the plugs. What do they look like. Are they wet?
3) How much oil did you put in the cylinders?
4) Are all the plugs properly wired?
