I actually ordered a new carburetor. The engine now runs better under idle, but still not perfect. Still surging, although a lot less than before. Under load, it runs normal, like before. Could it be that we are having the same problem @Chrisbowen. The problem might not be the carburetor at all...

I tried to get the choke shaft out. The idea was that the choke shaft was inserted/pressed through plastic float holder. I tried to pry it off, and the thing broke :=) . Picture attached. I'll epoxy nicely epoxy everything back together. But the question still remains, how did the guys in...

What I also found out today, I was wondering how does the engine ECU load sense. How does it know when to pickup the rpms, let's say that I pressed on the valve, or that I'm on the move with machine, surely there must be some sensor on the hydraulics. It turns out, no. The load sensing is a...

I see what you mean, it really is on the lean side, the butterfly can close completely. I have a good feeling that the thing will work with a bit of tunning. Ofcours if the servos find their way to reset to a known position zero :) I also found out why the choke doesnt work, the lever that does...

It poped off, it looked really clean. Altough different to what an idle jet looks like on a gx series, look here, timestamped mine has no brass insert. And a really small hole, picture attached. I think I'll buy some spare idle jets and have the hole measured and if it's the same size, I will...

I try to pry out the idle jet here does this go out just with prying?

No worries on the helping part :), just talking also helps The ECU or ECM of igx390 looks very similiar, at a first glance: https://support.surefireag.com/media/documents/iGX_390_Carburetor_Choke_and_Throttle_Motor_Parts_Diagram_5.18.2022.png Currently I'm thinking more in a line of how to...

And here is the throttle valve

Main jet and emulsion tube (the one with many small holes, am I correct?) are clean. The plastic jet I never opened, I will give it a try. I think I will anyway need to hardwire an open throttle, because I accidentaly turned the stepper motor gear, and I don't know if it the stepper motor will...

First some history. I bought a used spider lift that was fitted with honda igx440. The thing ran good only in summer, but even then, one had to always use starter spray to for cold starting. The igx series has no manual throttle, instead it has an ECU which drives the so called self tuning...

Hello again, and sorry for the thread hijack. I ordered compression tester, got it today, plugged it on. And it showed 100 psi. As far as I know, the number is good enough. So why is the engine having such a hard time idling. It sounds like it's gasping for air. What can be done? Can one...

Thank you, didn't know about this site. I previously ordered new coil (honda mechanic though it might be bad) for around 200$, turned out the old coil was good ;) Anyway, given that I would also have to pay import tax and shipping. And the possibility that engine won't run even with new parts...

Hello, I also had to battle this igx440 in the past year. I gave up. There are no spare parts available, no piston kits. Mine doesn't run in cold, it has bad compression. Even in summer it is hard to get it started. I will probably replace it with igx390, I just need to figure exactly which...
