After weeks of searching, the $800 carb came in for our 5K Onan generator at work. I swapped out the broken one with the new one. I set the jet to 1 1/2 turns out, and all I can get out of it is a loud pop with a small flame coming out of the carb. All the fuel and what I assume are vacuum lines and linkages are hooked up exactly like the old one.
This unit ran flawless before the plastic choke linkage broke on the old carb.
I've never worked with an Onan carb before, and it seems like an odd system...what do you all think I should try next?
