Im reviving this dead bg 75 and it's proving to be stubborn. Replaced fuel lines cleaned out gas tank ultra sonic cleaned the carb. Gaskets seemed reusable and the diaphrams were pliable. Primer bulb is not cracked. Cleaned off the air filter too and replaced starter cord. The carb is a walbro wt 413. Not made anymore and seem to be rare. Walbro says start at 1.25 turns out for the adjustment screws in their manual. Stihl says 1 turn out. The engine was flooding nonstop with both of those settings. So i tried tightening the screw clockwise about a quarter turn. Unflooded engine cleaned spark plug. Engine starts after first pull. I fully tune the carb and set idle speed to correct rpm. Put it in my car on its side. I come back and their is a puddle of fuel on my floor mat. The carb, air filter box, plastic housing, fuel lines, and gas tank were covered in gas so I cant pinpoint the leak. Let it sit upright overnight and didnt notice any leakage at all it seemed to mostly dry. Anyway i tried starting it again and it kept flooding probably from the leaked fuel. I had to tighten the adjustment screws more to get it to start and quickly open them more to avoid running lean. Anyway the thing wont stay running unless the idle low screw is about 3/4 turn out and same with the high speed. Since this contradicts both companies manuals Im apprehensive to run this thing adjusted at 3/4 because i dont want to burn up the engine. The only part of this blower I luckily havent had to crack open yet. Anybody have any tips here? Should I just not worry about it and run it like this because it seems to run right. Or is this carb or gaskets the culprit and not to risk it because itll burn up the engine. I guess I'm wondering if I could tell if its running lean. It just goes higher in rpm the leaner it goes so i dont want to try and push it to see if it does because 7k rpm with no oil will hurt this engine.
