I have a Mercarb 1389-8490 Serial number 6360589.
The instructions that came with the rebuild kit, and almost everywhere on here I read are to set the drop @ 1 3/32 (29mm). And float to 9/16 (14mm) When I took this carb apart I figured that somone was in here and had to adjusted WAY off. Well come to find out the service manual says it sould be 1 3/4 (44.5mm) and 5/8 (15.8mm). I'm at a loss, and not sure who to believe.
I adjusted the drop to 29mm last week and while on the lake fuel was dripping in the engine while off, never had this problem before so pretty positive it was from adjusting the float too high.
Also the pump rod it say to adjust to 29mm, this at least is the same everywhere I look, but no way , even if the rod was completey straight could I get it to 29.
Thanks for any replies
