I have a 115. It has been overhauled completely. Shop said everything is good. <br />The motor will not run at any speed accept idle, even that is not very smooth. <br />New plugs installed and gapped, lots of spark, nice blue arc, fuel is new. Compression is all 130psi. Numer 1 cyl is warmer than the other by some 60F, but cools down to the others as the engine runs longer. During acceleration the motor runs as if the timing is off, but it checked out ok. All test were done with motor on a stand.<br /> Any suggestions would be helpfull. <br />Thanks
