Re: 2003 Yam 2 stroke 115TXRB
on that yam it has choke butterflies not a primer system. it requires the choke to be held in while the engine is spinning. that motor starts easiest if you trim it to a level or negative trim, turn the key on,advance the warmup lever so it will be at 1500 or so when it starts, push the keyswitch in to activate the choke then turn it to the start position while holding it in to keep the choke activated.<br /> if its difficult to start using that method start looking for dirty carbs, a choke solinoid that is not properly adjusted or possibly a bad fuel pump diaphram. to "flood" a motor means excessive fuel. usually,especially if its in calm water, you can see the gas rainbow forming behind you and the plugs will be very wet and dripping fuel. not to be confused with the fact they normally are damp.<br /> but next time try my method of cranking.<br /> dont sweat it if it starts at 2000 you will learn about where 1500 is. remember this is not a 4 stroke, if it starts it has proper luberication. <br /> but yes if the motor is mechanically correct and the correct procedure for starting it is used they start very well and very rapidly. they dont like to start cold with no throttle advance.<br /> the 115,130 V4 yams are about the best out there for ease of use and reliability.<br /> remember if a battery cable or connection is getting weak it can draw all the current to the starter and not allow the choke to stay fully activated when cranking.<br /> a quick test is to try to start it with just the manual choke pulled.<br />if it starts easily with the manual choke pulled and not easily with the electric choke then you know what part of the system to look at.
