Hello Sir!

Okay, great. Thanks! (y) I think I've heard about that ”warped tank”... Below some photos. Is those the surfaces (marked with red arrows) that should be well sealed?

Thank you for the advice. Yes, it has to be a fuel problem. I have missed something. The carburator is a ”jet pulse” type, not very complicated but the problem is a total mystery for me. Is there some nozzle, intake or something that I should look and inspect especially carefully? Or some...

Hello! I need hard core expert level help with my Murray 5/25 engine. The engine works, pretty good, but I can't keep it running. If I actively adjust the choke then it runs somehow, but without that adjusting the engine stops. I have inspected the carburetor very carefully. Took it apart...

Yes, it's powering a mower, Murray 5/25. Yes I have. I have to tried do that very systematically and carefully. I get the motor started, it will run. Both idle, low and high rpm, there is power. BUT, only if I manually ”manage” and control it. That means, I keep an eye on and adjust the...

I ordered the Carburetor Kit for Briggs & Stratton from MSG Supply. Super fast delivery, thanks! (It took almost a month from my local post office to deliver the kit...) I managed to replace all the gaskets and parts, I also carefully inspected the carburetor. Looks clean and good. It also...

Very good video, thank you very much. (y)

Thank you for all the great advices. mfgsupply.com is a gold mine, thanks! Okay, I think my carburetor's throttle shaft bushings are more or less loose. Is there anything I can do? About the ”carb base warping”, I'm not sure where to look. This carburetor is quite simple... I tried to...

Thank for all the info. I have now removed the carburetor-tank-combo to my ”laboratory” for more detailed inspection. My plan is to first try some clean up and non-destructive studying... The engine is labeled: Briggs & Stratton 5hp Model 130902 Type 1237 01 Code...

Yes, exactly. If I put the screw back, it stops the engine. Okay, good advices, thanks to all. I'll remove the carburetor, clean it (and study)... I'll try that Berryman's B12 carb cleaner, too. Let's see how it goes!

Hello everybody! I need some help or advice with my Briggs and Stratton 5 hp (Model 130902). Tje problem seems to be with the Jet Pulse Carburetor. Very simple, but I'm lost! I can get it run but only without the airfilter – or more specific, without the screw in the middle of the...

Okay... I did not know that's possible. Propably that's going to happen here. Thanks for the alert. (I taped the filter because I suspected air leakin into the fuel...) Darn busy here, but I think I found from the manual (link above) some basic adjustments for the carburetor. I'll start with...

I think the electrics are fine and works. I think I have some problem with the fuel, carburetion. The hose with blue tape is the fuel hose. I wrapped the fuel filter with (blue) tape, I suspected a leak... I try to read the manual (link above) and found this: Check Carburetion Before making a...

Wow! I found this! https://www.manualslib.com/manual/863144/Briggs-And-Stratton-Twin-Cylinder-L-Head.html Pretty sure that this is the very same engine. Boxer, twin, 18 hp. I'm now reading this… For the smarter ones, is there something I should be especially carefull?

I couldn't find engines serial number. I have to look closer, no idea where the number is. My guess is that the engine is this >> Briggs & Stratton 422437. Gasoline, 2-cylinder, air-cooled horizontal-shaft, 693 cc / 42.3 ci, 13.4 kW / 18 hp.

Hello! I need step-by-step advice and instructions to get my trusty old Briggs & Startton, Twin engine (18 HP Briggs & Stratton I/C Series), boxer run better. Now it starts okay but runs just on choke, lazy etc. Not okay. ALL advice to normalise the engine setups are welcome! This engine is...

Mission accomplished. Thank you very much, you all! (y) Thanks for the tips and support. Shortly - it was not an easy effort (for me). I removed the four engine bolts and after that it is possible to lift up the engine to give enough clearance. In theory. Good thing is that I did NOT have to...

I think your memory is good. Thank you. Today I managed to loose the PTO belt, open the four bolts and look at this, image below, I think there's enough room to replace the start motor... Looking good. If everything goes okay, then I'll have the start motor replaced soon! Above left, the...

Yes, fun it is! I guess... I try to be smart and solve issues in advance. In this Gilson the engine seems to be with four bolts. Easy but the bolts and nuts are well hided. Let's see if I manage to do something this weekend. This is how it looks...

Yes, you are right, b it is. But, I'll try first the option C. I open/remove the four engine nuts so that the engine is loose. Maybe the cross joint - or cross joints - are flexible enough to let me lift the engine a bit and wiggle the start motor away... It is only about a centimeter or two...

I think you're right. But underneath doesn't work, can't access from there. It looks like I have to take the cross joint apart. That's two nuts. To do that I have to figure out a) the cross joint is visible from a narrow space, but I don't know… b) propably I have to remove the fuel tank...

Hello everybody! My trusty old Gilson S-Twin 18HP's startmotor should be replaced. I should remove the whole B&S two cylinder engine (horisontal axel) before replacing the start motor but I do not know how. Above, you can see the start moror between the cylinder and the frame. The engine is...

Okay, that's a fresh idea. I'll try the ”reverse coil”, thanks. Yes, the magnets are strong and healthy. This case is a total mystery for me. I just don't get it… I think I'll inspect the kill-wire one more time, too. Could it be somehow that it has to be connected somewhere for the ignition?

Hello everybody! I'm totally out of ideas why my 250 cc Kubota engine won't start. Everything was okay but the next day the engine would not start. No spark. The sparkplug seems to be okay, I replaced the ignition coil - and the wires - to new one. I disconnected the kill wire... Nothing, no...

Darn... I got a new coil by mail. Replaced it. But no spark :-( Any idea what it could be? I was sure it would be this ignition coil but there is something else. Everything seems to be okay but no spark.

Yes, good advice. I did that but not really helping. It seems that Kubota is these days not much about these small engines but more about tractors and bigger stuff. So far I have found plenty of info about this Kubota GH250 engine, YouTube videos, manuals and brochures — but surprisingly little...

Good tip, great work - thank you very much. I'll put here later some results how I succeed. Looking already good.

Thanks! I'm not sure if I got it right. The url is to Google search… None of the Google suggestions are to part supplier for Kubota gasoline engines :-( I think I somehow get different search results. I wonder if there/somewhere is a way to find a ingnition coil by measures?

Hello everybody! Any idea/suggestions about where/how to find a replacement for this ignition coil? JAPAN KOKUSAN DENKI BM3618-3E26 (It's from a Kubota GH250-Q-1-SO-UK2 engine) All tips and ideas welcome! Thanks

Finally I managed to remove the coil (not easy, I had to dismantle a whole lot of parts before that…). It has markings: JAPAN KOKUSAN DENKI BM3618-3E26 Here some photos. The holes are ø 5,5 mm (1/5"), and 55 mm (2.16") apart. Any idea where/how to find a replacement?

Yes, I do live i Europe. This engine is in a Ransomes Triple 18 mower. I do not know much about this, the year model is maybe 1980's... The manual says »Kubota GH250-Q-1-SO-UK2». I haven't inspected the engine close enough, yet. I'll post here some info and photos of this repair as soon as the...

You're right. I don't know how usual it is that the coil goes bad (the transistors inside it), this would be the first time for me. So far I haven't find a spare coil for this Kubota GH-250 engine...

Thank you! Good tip!

Yes I did (I learned that from YouTube 😀). My next step is to remove the whole Kubota engine, test it well, remove the flywheel... So far it looks that no spark, and I have not found any reason. I'll try to measure the coil AND order already a new one from somwhere. BTW - the engine worked...

Hello Everybody! Any idea where to get/order the ignition coil to Kubota GH250-Q-1-SO-UK2? OR any suggestions why there's no spark? I think the plug is okay, the kill wire is okay... All ideas and advice are welcome! Thanks in advance!
