Several of you recomended that i clean the gas tank before i attempt a start... i agree as it appears to be pretty shady in there, and somewhat varnished!! but what is the best way to go about this???? any ideas?? ALSO what sort of oil do you use in the gear box on these PUCHS?? is just 90 w gear oil ok?? and my piston deffinetly is a little stuck in the cylinder i have been fogging it with WD-40 from top end side as well as into the intake, but i want to use a better penetrating oil, and recomendations here?? or any other secret techniques to getting pistons UNSTUCK!?!?!?!? thanks any help is greatly appreciated!!!!
