Good afternoon chaps. I have finally gotten round to dismantling the engine further - earlier removed the cylinder head and exhaust - very pleased to see such little wear to the internals and crank etc. Being on a roll, I decided to dismantle the carb in anticipation for the arrival of the new diaphragm from webhead - I've discovered something a little strange. (And that perhaps I should have inspected the carb sooner!) It appears that the diaphragm is actually in pretty good shape but.. There are a couple of bits missing! (See image below) -Diaphragm ball valve -Diaphragm arm -Diaphragm arm spring -Diaphragm disk There isn't a gasket either but I'm told this isn't required and can be reassembled without. I assume the carburetor won't function correctly without the ball valve, arm, spring and disk - does anyone have these spare that I could purchase them from? I'm hoping for no more surprises with this engine, nonetheless still enjoying the project. Cheers

Hi David, Hope your weekend has been nice thus far. I potentially have a replacement needle valve via webhead as per your suggestion, many thanks to both on that matter. In regards to the fuel tank, I've managed to clear the majority of the gunk inside (still soaking on third round of petrol + nails/junk) and have cleared the two breather feeds on the tank with no problems. The fuel feed (internal to the tank) that goes to the carb still seems to be blocked (no flow through of fuel, even when inverting the tank) - any ideas are welcomed, would prefer not to crack open the bottom unless I'm left with no other option. Also, the gasket/paper seal for the fuel tank cap is long since gone/perished, can a new one be fashioned from thick card or similar? Cheers Many thanks - have dropped you a PM.. 👍

Hi David. Thank you for your detailed response. In regard to the needle valve, as shown in the picture I uploaded, is all I have unfortunately, there does however appear to be a seal of sorts upon to the top of the housing for the needle screw. It's marked slightly and the original was damaged/broken due to over-tightening from small hands - hoping the housing is fine, I will try to get better pictures uploaded tomorrow for that. Thank you for the links and info on bolts, I will be ordering some fairly soon I'm sure. Any label upon the band itself is long since gone which is a shame but once it fires we shall know for sure either way. Sounds like a 110v (& 12v) @ 300w as you suggest. As for the fuel tank, I'm going to give it a good clean as the (inside) bottom of the tank is gunked up quite badly. Will petrol be suffice to clean it up? Cheers.

Morning David. Many thanks for the warm welcome and quick response. In regard to the carburetor needle, I have included a picture below so you may see the damage that occured. Please let me know how much you require for the replacement, I am able to send the broken one back to you if you feel it's fixable? Haven't seen this needle type on other engines, not sure if it matters? Thank you for the information pertaining to the spark plug - I have ordered 2 fresh ones. I shall check the contact points with a meter later today, they looked relatively clean on first inspection though so perhaps it'll give us a better idea of what's up. In relation to the nuts/bolts I did have a feeling they wouldn't be easy to obtain - the flywheel cover for mine came with two screws missing and wondered how easily replaced they would/wouldn't be. Lastly, regarding the Philippines, indeed the distributor there appeared to import them from the US, I forget where, but on this basis I would assume 110v rather than 240v, I shall confirm this once we have it running again either way. The owner was under the impression it was 120v and 12v @ 9amps , depending on which output you took from the generator. We shall see soon enough 👌🏼 Progress yesterday was slow, but did manage to polish and remove all traces of rust and the majority of surface pitting to the air filter housing and muffler, cleaned the base plate, handle and fuel tank of any corrosion/tarnishing too.

Good evening folks. Very impressed with all the work I've read about on keeping these beauties running. First off.. here's the engine! I am under the impression I can get a replacement diaphragm/gasket and intend to do so provided they're still available? That aside, the needle screw valve on my engine carburetor was sheared from overtightening by small fingers! Is there a suitable replacement for these? (I will attach a photo when possible) I was surprised to find the original air filter foam intact and healthy albeit a little darkened. (See small bag below right of tank) The previous owner had cherished this engine for many a hike in the mountains. The care shows, it's just unfortunate that small fingers damaged some things. I have repaired the starter which had been over-pulled and jammed. Fairly confident compression is good, are replacement spark plugs easy to source? I also wondered if there is anyone with knowledge of coil/condenser repair? These parts of the engine have developed a fault and is choosing not to spark. Will check more closely tomorrow to be certain but I fear internal breakdown of the coil. Is it possible to get new bolts/screws for these at all? Did I mention the engine&generator have travelled to the UK with me, all the way from the Philippines? Thanks in advance. Cheers VID_78680702_145534_379.mp4
