sorry for late reply, was really busy. You were right, the leak doesn't mean much. Replaced the gasket at the intake manifold (both), still nothing (BTW. both gaskets are "DIY", hard to get legit ones). Surges but less. The springs are worrying, but I imagine it doesn't mean much until the...

Hello again. Removed the intake manifold to check for any cracks (as I can't remove the cover while the engine runs as the dipstick is stuck to the cover). Gasket seems fine so I filled the manifold with water and it shown multiple leaks at the engine side. Putting the water under pressure...

Hello again. It definetly has too much air (or not enough fuel to be exact). When I manually use the choke lever on the carb, and manually close it about 20% the engine smooths out how it should run. When I let off of the lever, it returns back to surging. Same for when I manually block the...

Thanks for your quick reply. Tried spraying WD40 between the carb and intake manifold and nothing changed. Will try spraying it on the intake manifold next time. Figured the springs were setup wrong, but changing it did absolutely nothing but lower the RPMs. Also, didn't note before: I put a...

Hello folks, back with a good old surging issue. It's a Briggs 675EX Quantum engine with surging issues. At first it was horrible when it arrived. Replaced the air filter, removed and cleaned the carb, replaced bowl seal and assembled it all. Ran much much better afterwards but not perfect at...

Hi and thanks for the answer! Never gave it any thought... a screw for me means it's adjustable, my bad. See the images, hope they help. The ignition is a simple magneto directly tied to sparkplug, nothing else. Sure I'll post the ID tommorow, couldn't make it yet. Also, it doesn't mean too...

Hello folks, I can not get my BVS153/Vantage engine to run smoothly. It not that it revs up and down and such governor issues, it's more like constant smaller misfires and non consistent running. No matter low or high throttle, it always has that issue. It doesn't bog down when under load, or...

Hey and thanks anyone for the given help At the end, it was the air filter I put in. It isn't the original one, so issues were expected. As it was too thin, the air/fuel mixture was wrong and governor went nuts all the time. I added more filter material, dipped it into oil and adjusted the...

Thanks for the answer, but sadly not possible. Literally no Yamaha dealers in my area, or even remotely close. Also, if there was one, I hardly believe they would repair a generator from the 90's. Buying the manual is more than what the repair is worth. Thanks anyways!

Hello folks, so I have gotten a Yamaha EF600. At first, it didn't run at all as fuel leaked from the fuel pump/cock located under the gas tank that pushes gas up to the carb, and cycles back to the tank. I cleaned the pump, as it was totally blocked, afterwards no leaks were to be seen and it...

Thanks for the tip! For now it's "fine". I don't really expect much from it anymore.

Hi everyone, sorry for later answer. Thanks everyone for their answers! Thankfully, I think it was (once-again) the dirty carb, atleast for now - it works (as much as the bad carb design allows it to). I opened it up again, cleaned it throughout, completely took apart the white "cartridge"...

Hi once again. So I tried a different tank, w/o the fuel filter and the same issue. It starts running nice up until fully warm or put slightly uphill. Currently I'm cleaning the carb, once again. I'll see if that helps anyhow. Can you also please explain how you managed to get the choke...

Hi and thanks for your reply. So, pulled off the breather tube and it ran actually good for a minute or so. Next start, and it ran bad (still, better a bit) yet again. It definetly did help, but not for too long, I imagine until it warmed up fully. Nothing can be noticed to be coming out of...

Hello folks, so one of those engines with the plastic carbs without a primer bulb, with the white "cartridge" in it, a 625EXI engine has issues with the RPM/throttle surging up and down. Before this happend, the engine refused to run properly at all, so I took the carb apart, cleaned it, the...
