PS, some guys use “Red Kote” gas tank sealer, I use the hot fuel proof model airplane dope.
PPS, as for no alky gas, i’m fortunate that it’s readly available here in S-E MI. However, I see that the premix two cycle gas is now available at hardware and big-box stores. Comes in 50:1 and 40:1 , pure gasoline, no alky. Kinda’ expensive. You will have to add some oil to get to the ratios that we commonly use.
