Hello Dewitt welcome to YT. Interesting that you installed a turbo on a tractor not even knowing the difference between a blow through or drawn through system. So if the compressor side of the turbo is hooked to the intake of the carb you have it set up as a blow through system. In this case certain areas inside the carb need to be pressurized with the charge air pressure as well. In other words when you start boosting the carb the pressure essentially pushes the gas back in the fuel bowl out of the main jet. I am not in the know about what all needs to be changed to make that work. In the attached archive YT post it looks like the poster did the same thing as you did, but yes he has a fuel pump on it. Using a blow through system does get away from the lag of the fuel mixture changes; in other words throttle changes of a draw through system that puts the carb before the turbo compressor. In some applications I have seen the carb placed in a enclosed box that is all pressurized by the charge air. The fuel in that case would definitely need to be pressured with a pump several psi above the max boost pressure. If you web search Farmall Keystone turbo you will see the kit they offer for a 350 which is essentially an H engine with more cubes. Their kit has a reconfigured intake manifold to accommodate a draw through system going that way eliminates a lot of issues with how the boost affects the carb operation, but as said above has other drawbacks. BTW poster 1949H with the turbo H in the post attached has not posted here since 2014.

Today's Featured Article - When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
