Ok so here is an update. It was my dad who diagnosed the coil, so I ordered one and fitted it. Found out the MS261 needs to be pulled over fast to get a spark. Still would not run but getting smoke from exhaust and every so often sounded like it wanted to. Spoke to my dad, “what happened” “it sounded like it was running out of fuel, put fuel in and would not start again” I have checked the key - all ok I have refitted the old coil and give it a good pull - it has a spark Tried to start and still the same, throttle wide open and plenty of smoke on each pull but will not fire. Tried brake cleaner again - no start Disconnected kill switch and still the same Compression feels ok Any ideas anyone? Could it be fuel solenoid? Why not fire of brake cleaner. Been used plenty this year with no issue

Sorry mate @Stubby

Let me check and I will report back, thank you @spudulike

Hi @spudulike I gave L&S engineering the serial number and they gave me the part number for the replacement which i ordered. It is weird, I have spark and it sounds like it wants to fire on first 1-2 pulls, smoke from exhaust but then there is a change in the noise and no smoke. Tried brake cleaner straight into the bore and it still would not fire Thank you for your support.

Hi all, I have a 2015 MS261C originally had no spark but that’s because I was not pulling it over quick enough after a new coil. Now it will not start, could it be the fuel solenoid? How can I test the solenoid? Does anyone have any ideas, anything common I should be looking for? Thank you in advance Phill

It could be your own if the dense air is coming down your chimney and vents care left open. Would be worth checking if her stove is lit when you are experiencing this. Smoke test will confirm any leaks

Hi there, I have a external flue so it may not be your issue but I find that if we have a cold / damp evening the cold air is dense and pushes the Smokey smell back in the room, usually notice it of a morning when I come downstairs. Traditional chimneys are usually ok but don’t know your environment.

Hi, I am looking to buy a wagon load of timber for firewood. It does not need to be pretty as it will not be going through a processor. Would anyone have any contacts? Also able to collect smaller loads in a close radius to outskirts of Liverpool. We have a few stoves in the family and our usual supply is no longer available. Thank you in advance.

@stubby nothing worse than reading a thread to get to the end and find there is no feedback if the issue was resolved. I have wasted a lot of time due to that.

Hi @paddy1000111 & @wonky if we ever cross paths, I owe you both a pint. Striped the carb back down, nothing obvious but blew it all out. No sign of blockages or debris but built it back up. She started much better and back to firing on two cylinders again. Really appreciate you taking the time to offer advice. Cheers, Phill.

Hi @Paddy1000111 & @Wonky really appreciate your replies. I have swapped out the plugs and filter already to rule them out. I have had the carb apart but will check that again just to be 100%, I need to check the inlet arrangement as well to see how fuel is drawn into each cylinder. Looking at the coils, it does say they are handed but I am wondering if that is just down to the length of the leads? If they are not sealed then I may swap the coils around. Will also check the air gaps too. Thank again for you support and appreciate the time you have take to pull out assembly drawings etc.

Hi all, finally got round to taking a look again today. Done a compression test on both cylinders wet and dry, both measured around the same and all reading’s are within the spec from the manual (85psi dry / 95psi wet) I checked the temperature on each cylinder and it seems one side is not firing as it’s not getting warm, I pulled the lead and no difference but pulled the other side and it stalled. With the plug out, it is sparking but it does seem to be slightly damp. Has anyone had this issue before, next thing to check is if the coils are handed so I can swap them to try and rule out the coil. Thank you in advance

Hi@wonky thank you for extensive reply, you have given me plenty to go at here. The issue I have is that I do not know the full history of the engine. It’s starts fine hot and cold, there is no smoke and it does not use oil. The oil may not have been changed regularly enough as it does not get used a lot but totally understand what your saying. I am almost certain there is no spark screen but will check. Next think to check is compression and governor. I will report back, thank you.

Hi all, Looking for some help with a Honda GX670 24HP engine. The engine is down on power, to the point it stalls when engaging the fly wheel If you do not engage it really slowly (Flywheel spins freely so it’s not that. I have checked the obvious such as plugs, valve clearance, fuel filter, cleaned the carb but still no different. Has anyone had similar faults or have any ideas? It would be appreciated. Thank you in advance.

Hi, what is the heat output like?
