Hey leut, I got me last year a swallow and the smoke out of the back like sow has also not really got a suit must turn up in the 1st course until hit that the one continues in the second. It’s a KR51/1 K BJ 76 driving a mix of 1:33 so from which the actually can not smoke. Müsche 15w40 oil pure so the cheapest can it lie there from the exhaust drips also full of the black shit so when it rains it gets colorful think but firm it is oil I know however nic het like the previous owner who drove when he mixed her with 1:50 she will probably be very rusty. what can I do?
