Small engine trouble

[Sodo]

I went 5 years having ZERO problems using big-name E10 gas, then switched to no-name pure-gas and trouble started within 2 months in every engine I used the puregas in. Carbs all came apart and cleaned, some had to do it twice. But I got to them quick so no corrosion and now I'm back to E10 and everything's running good. Gotta wonder how much trouble is caused by not knowing which type of gas is actually causing the problem. It could be from switching back and forth. I recommend folks to consider this possibility, keep eyes open to all solutions. And who knows what formulations are used around the country.

It's sure feasible that focus on the wrong enemy is why some folks are having trouble and others not. I'm going back to what worked for me Shell, Chevron E10. I don't know what to do in the 3 weeks of summer (95F +) when the E10 boils (so far only in the chainsaws). Everything else ran fine on the E10 even in the summer. My cars/trucks/motorcycles too. But I hope to find a solution for the saws boiling. Sorry for your carb trouble, I was able to clean all of mine.

Our small engine shops and marinas are filled with people's small engines with fueling problems. The issue comes up when an engine is not used for six weeks and primarily the idle passages dry out leaving behind a white, chalky substance that clogs the passage. Ethanol also draws water vapor out of the sky through the fuel tank's vent cap allowing water to collect which also causes problems. Water in fuel isn't such a problem with small power equipment, but is a massive problem with marine applications and especially in hull fuel cell applications.

Well it's a moving target anyway (for every president since George Bush Sr. made the deal with the Corn lobby. :laughing

Something to try. Move the throttle butterfly on the carb to the full open position, while watching what direction the governor arm moves. Like if the governor arm moves to the left when looking at it, then turn the shaft counterclockwise. Now while holding the throttle at full open, can be done by a throttle cable if it has one, loosen the clamping screw at the bottom of the governor arm and turn the shaft in the same direction as the governor arm moved in the previous step, and then retighten the clamp and see what happens. Maybe you twisted the arm on the shaft throwing the static governor position off.

If that doesn't fix it, that may mean that the governor gear had broken. You may need to hold the governor shaft in place while tightening because I have seen some back off because of the position of the governor arm inside the block.

YOU!!! Are The MAN!!!! :number1: I kept feeling like it was a governor problem the whole time, but when I took that mechanism all apart it looked to operate fine. Of course there is no way to really test it since the mechanism sits in the crank cover, but the shaft is in the crankcase, so you can't try it when opened up to see it. I wasn't quite sure which way to turn it even after reading your instructions, so I marked it at home position, tried one way (nope), then tried the other and BINGO!!!! It sure didn't take much of a turn, but it made a HUGE difference. Probably 3-5 degrees. I had no idea that was even a possible adjustment. The throttle now throttles, the governor governs, and the splitter splits. All is right in the world. I could have saved myself the price of a carb if I had known that earlier, but STILL dang glad I know it now!

A HUGE thank you for this!!!:thumbsup::drink::drink: If you find yourself in the Twin Cities, there will be cold beer waiting for you!

Awesome news Dave! One of the many things I love about TBN is there is always someone who has the answer and is willing to help. Now bring that thing down here and let's split some wood.

Thanks Jack. I'll be right down...after you post those pics you promised on your build thread!

 

[SirReal63]

I have to take some more first.

When you're done at Jacks place, y'all come over here!

But Dave, I developed a hankering for "Point" beer from Wisconsin. So if you'll bring it down, I'll pay you for it.

 

[dstig1]

On my way!

Did someone say free beer?
