My Restoration Thread

[Traveler2586]

Did you try squeezing the primer bulb to make sure the carb(s) was full of fuel? It sounds like it's a fuel problem, and the engine is not getting fuel after sitting without running for a few hours.

Do you have fresh fuel in your tank? Stale fuel might run and start an engine that is warmed up, but not a cold engine.

I agree with Tom, I had this problem once and found fuel was draining back down to the fuel tank through the squeeze bulb. But didn't you just get a new bulb? Is it facing in the correct direction? The arrow points to the engine, but if it's in wrong I think it would block fuel flow. Check hose connections, an air leak into the fuel line will kill the syphon effect.

well, i replaced the bulb last year... i replaced the fuel lines, and all the connections are tight.... and yes, if the bulb was facng the wrong way it wouldnt allow fuel to pass, as it acts as a check valve....

also, even though i didnt fill the bulb during the day, i made sure it was really full at the beginning of the day, and even then, i had to spray carb cleaner on the carbs for the motor to start.... last week, when i first started the motor after all year without using it, i spent almost 1/2 hour cranking and pouring cab cleaner, until it started.... but once it started and left it run for a while, i could trn it off and then it would turn on again really easy....

now, the first time i start it for the day, it will take several sprays... after than, it if doesnt turns on, it will only require one small burst of carb cleaner....

i will check the spark plugs, but i replaced them lately so i dont expect them to be dirty or burnt... and i think ill replace the gas filter also...

any other idea??

thanx!

Do your carbs have floats? You could check your float level and the inlet. Those floats do wear out. Had a fourwheeler once that when cold loved the carb cleaner and ended having to change the float even though it looked fine.

Some of the gas in your bowl will dissipate fairly quickly as it sits and that is normal. If your float level is too low after the dissipation it will be harder starting. I think this is less likely seeing as how you have two carbs, just tossing an idea out there. Too much gas in the bowl if also a bad thing.

thanx, i will check on that... i have got stuck floats on other motors, but not on this one... how do you check the level??

also, here is a pic of the fish i caught on sunday, my new PB.... catching it made all the work on the boat really worth it....

At cranking RPM a slightly low float might not create the pressure you need to get the gas to the engine. Cold motors need a richer mixture to start (thats what the choke is for). I would make sure your chokes are working first. At running RPM you would not notice a slightly low float because the pressure is great enough to get the fuel to the engine. You said you cleaned the carbs out, you may have bent the tab on the float a bit accidentally especially if you pulled on the float too much to clean the bowl instead of taking if off the pivot pin (hinge). There is a tab on that hinge that you bend SLIGHTLY to adjust your float level. I really think you need a manual. You will need to measure your float level from the bottom of the bowl and it needs to be where the manufacturer wants it. Adjusting your float level is not a way to compensate for a rich or lean air:gas mixture. Usually, but I cannot say ALWAYS, the float needs to be even with the bowl body WITHOUT the gasket on it. If your float pin is visibly worn you will want to replace the float.

If your engine is a 2-stroke I would not spray carb cleaner in it to start it. There is no oil in the carb cleaner to lubricate your pistons. If you need to, pre-mix some gas and oil to use as your starter fluid.

Like above though, I would also check the primer bulb, and make sure there is no air leak before the bulb. Also could check your fuel pump and replacing the fuel filter wouldn't hurt.

Edit: Some carbs have a window on them so you can see the fuel level in the bowl. If yours doesn't, you can run a clear tube off the the drain on the bottom of the bowl and hold it up next to the bowl to check the fuel level, but this won't help you unless you know where the fuel level should be.

When you cleaned your carbs, did you remove the high and low speed needles when you blew out the jets? If so, you may need to adjust the low speed jet, just counting turns when replacing the needles will get you close but not exact. Also, if you didn't blow out the jets they may have some build up in them restricting the fuel flow.

Great work! Heading down the home stretch, keep up the good work.

Any updates?

unfortunately, fishing season got in the way.... the boat is running great, but all the spare time we get, which is not much, is used for fishing... we have been out only 3 weekends since July, so as you see, we dont have much spare time, and the little we have, we fish.... but we WILL add the deck extension, decals and everything, and, in the future, fix or most probable rebuild the trailer...

oh, i forgot, the most recent update was that i replaced the steering wheel, no pics of it though....

did a little more progress yesterday....

since days are getting shorter, most of the times darkness will come with us still in the water.... so i got some LEDs and installed them as courtesy lights. i installed one under the console and 2 were temporarily installed in the original rod locker, when we modify it we will move this lights to another place, but for now, it works where they are....
