Hi Nigel, yes i have had to replace the carb due to mine not working. The original rear mounted needle is bypassed, and the fuel line goes straight to the front carb mounted high speed mixture screw. I didnt have shorted srews to replace the rear mounted bracket. Thanks for the link to the manual, mine went walkabouts years ago. Hi Keith, Thanks again for your help. I did run the engine yesterday for a few mins, it ran really well, i had forgotten how much of a mess that these little engines make!! I am going to strip the cowl again today and tune the carb as per your instructions, and start again. I am still waiting for a new glow battery, so ill crack on with that. Ill report back once i have some progress. Cheers, and thanks again

Hi Julian, Thanks for that, I think i am finally sorted, i have now 3 leads to get the cable. I did call that numbner but i didnt get through and no reply, might have been a busy time. Ill try to contact them tomorrow, thanks again for your help.

Hi caveman, Im so sorry, I have only seen this. I have just realised that the kit i received should have had the larger version aswell, but it was missing. I have just emailed them now. Send me a pm, Ill check the diameter in mm on mine again tm. I really appreciate the help, I am honestly really really overwhelmed with the support and time that everyone takes to help those in need.. I just hope someday when i get up to speed i can help in return someday....maybe on 35mhz gear!!! Cheers

Hi Caveman, yes i did, Ive tried to contact that company you mentioned, but i havnt received a reply yet, ill try again tm. I have two other suppliers at the moment checking if it will fit. Thanks for your help. Hi Keith, perhaps i am. Now that you mentioned it, i was wondering how that screw changed the Idle mix. So it did actually start, but my glow battery (also 20 years old) failed. New one ordered. So i have the pictures here, will you tell me which one you are talking about? Now i am thinking that the idle mix is the one at the side, eg straight into the barrel of the carb, the idle stop screw is on top of the housing, and the high speed needle is on the side above. I will strip it out again tm and start again. Thank you for your paitence, an help!! Do I have this right? Thanking you in advance

hi Keith, I cant thank you enough for the post, a great and very detailed description. I have new fuel and a new glow plug. So I will tune the carb first then try to start it. My plan is to get it set up with a long pushrod by hand for the throttle link to the carb, and once i find the settings, I will connect the servo with the throttle at idle but the trim at full. then I can back off the idle screw and use the trim to cut the engine. It worked for me in the past. Its all coming back to me. I still need to replace the hinges with better hinges with metal pins, and i think i will replace the ailerons, they are wobbling about a lot. a small bit of covering at the aft trailing edge over the fuselage, and fit the new bands. Once that is done and the engine is working, Its ready for a test flight. Is it still c of g approx 1/3 back from the leading edge? Im hoping to get it test flown by a local instructor by the end of the week. Amazingly the model is still registered with the same tail number, so once my insurance cert arrives from the club, Im good to go. I just need to get the cable for my controller to connect to the computer, so i can get my cashes out of the way in a virtual role!! thanks again for all of the help. Regards

So a bit of work today, All tested except the engine. I still need to replace the hinges with new ones, thats for tomorrow. So tomorrow i eill be starting the engine for the first time in 20 years. I have new fuel and a new glow plug. I am having trouble finding the initial settings of the high speed needle and the low speed screw. Does anyone have any idea of them? Its for an SC 40. Here is the pics of the model. Cheers

here are some photos

Hi all, Quick update. Finally parts ordered, i should have Nitro, solarfilm, a fuel pump, bands, balsa for the ailerons and wing tips, and i received yesterday the sc 40 engine. So im good to go. the local flying club is still under a restriction, but i have an instructor who is going to test fly the model for me, and get it set up. So the 1st model will be ready for test flight this week. Its a yamamoto 1600, sc40 35mhz sanwa. I just need to install the engine and fuel tank, cover a small part of the wing, and refix the control surfaces using proper hinges. the mylar ones just kept failing off over time. the second model is a very basic trainer that i was rebuilding into a cub type replica. That needs to be covered totally, new ailerons made and covered, the mds 40 engine fitted, fuel tank, and the servos installed. It is also flown with a sanwa vanguard 4 channel 35mhz tranceiver. I have just finished the tailplane in a cub style, and the tailwheel has been ordered for delivery tomorrow. I will update with some more pictures when i get it done. The cable for the simulator arrived, but it was the wrong type, it was too small, so i am still hunting for that. Cheers
