Hello, I drive a 1957 pontoon 190 and have the following problem: after the carburetting (completely disassembly and clean) the car ran quite well again. Before, the seal to the float chamber was damaged. At the first bigger exit I then accelerated to 130KM/H. After that the engine almost did not run at all and only had to be brought home with pulled Choke. Later I unscrewed the idle nozzle and cleaned – although I nic It can really say that it had been clogged. The engine runs through again at the moment in idle, but very unevenly. When giving gas in the stand, the rucksack is detected during the ride, because the engine shakes irregularly. If the engine runs in idle, one hears a slight irregular patching in the carburettor. I also sprayed the entire intake tract and also the carburettor with petrol to exclude possible side air. When accelerating in the stand it can sometimes be n that he throws a flame out of the carburetor – but not excessive. During the ride he smoothly accepts gas. I am at the end with my Latin and would be grateful for help. Greetings
