I have a 2010 Tohatsu 4hp longshaft with carb upgrade to 6hp new for Spring 2011. The motor had sat idle for a month and then was used this past weekend. Iniially it took 6 - 7 pulls to start and then ran as normal - assumed this was from sitting for a month. Used the motor 4 times that day. On fourth time the motor started and then after about a minute died. While trying to restart I noticed fuel coming out of casing and dripping into water. With cowling off the fuel was actually spitting out the screened vent near the carb.
We assumed the float was stuck or something similar so we tapped the carb several times and tried again. Engine tried to start and then went back to same problem. During this time we had choke in OFF position and throttle wide open. Repeated the exercise of tapping the carb and after two or three more pulls the engine started. Ran well and the next morning when tried again ran properly as well.
Assuming there may have been dirt or something in the fuel that caused this.
Any comments on what may have been the problem and wondering if I should be trying a fuel additive of any sort to help clean. Will be using the boat one more weekend and then hauling for season and will be taking the engine in for winter servicing at that time anyway.
Thoughts?
