I bought a brand mini airboat w/40 kohler. The boat looks exactly like the picture on this homepage. Bought it last march. Used it 3 times in March. It ran perfectly and have not turn it on until now. I can't get it started so my buddy helped me clean out the carburator. it is all clogged up. Got it started, took it to the river but it died when I rev up to 2500 rpm. appears to be lack of gas to I bought a brand new electric fuel pump from Kohler (Facet 7gph, 1 to 2 psi) , installed it and back to the river. It die when I rev up to 3000 rpm. again, it appears that the carburator is not getting enough gas. Could this fuel pump be too week even it is what Kohler recommended but might not work for airboat application. Could someone help me troubleshoot this problem. I am an engine idiot so please be patient.
Thanks,
