∙ 15y agoAssuming the carburetor is clean and the float operates properly and the air filter is ok: Initial setting: Close needle valve (rotate clockwise) until it just touches (do not over-tighten or it may be damaged). Open needle valve (rotate counter clockwise) 1-1/4 to 1-1/2 turns. Start engine and allow to warm up approximately 5 minutes. Fine tuning: After engine is warmed up, S-L-O-W-L-Y close needle valve until engine starts to stall for lack of fuel, then S-L-O-W-L-Y open until engine starts to stall for too much fuel. Set the needle valve in-between the two points. Additional tuning: If engine bogs under a load or while mowing, open needle valve 1/8 turn for a slightly richer mixture.
