Setting the carb on my early 1650 gas. I believe the carb is a Marvel Schebler TSX 807. I am looking for baseline settings for idle and main fuel mixture screws. Of course my 550 and 1850 manuals list baseline settings, but my 1650 Oliver and I&T manuals do not. Just looking for a good place to start.
Secondly, the idle mixture screw appears to be in great shape. Runs down smoothly and seats as it should. The main fuel mixture screw, on the other hand, was difficult to run down and I am not feeling a definite bottoming of that screw. I took it out and the threads look beat up. I am going to inspect the bore threads in the carb tonight. A few searches online did not turn up much in the way of a new main fuel mixture screw. Anyone know of a source for a new screw?
Thanks in advance.
