Hi Folks. I have a 1990 Johnson 4 hp that I bought recently (not running) with a suspected carburetor problem. Having fixed carbs previously I stripped this down, it looked very clean but I cleaned it again. The issue is that fuel is coming to the carb but not through it.
The float did not looked balanced and the pin was clipped through a hole in the arm of the float so I sorted that out, and got the float level. When I put it all back together and try to blow through the carb's fuel in-take it's blocked. When i remove the pin (from the seat in the carb bowl) I can blow fine through it.... the pin looks new, the float looks fine... is it possible that the seat for the pin is too tight? is there another way to adjust this/
Slow/Idle adjustment needle needs a new washer but I've put in one that should work okay, so I dont think that's a problem. Also when I spray gas into the carb it turns over ok... I've also confirmed that there is fuel coming to the hose attached to the carb's fuel intake. Any ideas? Thanks in advance.
