flyingfleasteve Posted May 23, 2021 Author Share Posted May 23, 2021 Thanks all. after piecing the clutch basket and center driver together I am not happy as the bearings appear a little tight and pinching in places. I suspected the central spacer, inside the ring of bearings, has warn slight and needs replacing giving a little more tolerance. With the clutch put to one side I have managed to remedy the warping to the carb block by splitting it from the lower section, heating with a few choice taps with a drift and hammer. Now that’s sorted I have cleaned it all up and popped it back together. Fully serviced its on the bike and ready to go. The slider and choke feel much smoother but the slider is now not quite as tight as I would like, I will see how it runs and evaluate it from there.

Ron Posted May 23, 2021 Share Posted May 23, 2021 It probably doesn't matter, but you still have the leak hole in your jet block that the document quotes, shouldn't be there. Ron Quote Link to comment Share on other sites More sharing options...
welbike Posted May 24, 2021 Share Posted May 24, 2021 Ok, I have found a Jet block with the hole, but will strip the carb that is on the bike now first, that was done by Martyn, so it will be plugged up already! But better make sure the carb is 100% as it's a real pain to remove once the tank is on the bike Steve! Cheers, Lex Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted May 24, 2021 Author Share Posted May 24, 2021 Thanks gents! Really helpful! Just to confirm, this is the hole I need to block up? Quote Link to comment Share on other sites More sharing options...
Ron Posted May 24, 2021 Share Posted May 24, 2021 Yes that's the one Steve. Actually Lex when Martyn did mine, he had no idea about this until I gave him a copy of the document. Ron Quote Link to comment Share on other sites More sharing options...
Chris Hall Posted May 24, 2021 Share Posted May 24, 2021 A dab of solder should sort it. Quote Link to comment Share on other sites More sharing options...

Just bead blasted the body, and will assemble soon. Cheers, Lex Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted May 28, 2021 Author Share Posted May 28, 2021 Looking good Lex! Out of curiosity have you any photos of the correct fuel taps and fuel line? I am going to make the fuel line and top rocker box oil feed line, am I correct in assuming the pipe is standard 1/4”? Quote Link to comment Share on other sites More sharing options...
Ron Posted May 28, 2021 Share Posted May 28, 2021 (edited) Funnily enough Steve, I recently converted my "two Tap" system back to what it should be by the book. (one tap and a balance pipe.) I expect Lex will agree that it's not an ideal system, but I wanted the challenge of getting it correct . Yes it's 1/4" pipe.

welbike Posted May 28, 2021 Share Posted May 28, 2021 Well, I was under the impression, that only early G3L's had that system Ron?? Lex Quote Link to comment Share on other sites More sharing options...
welbike Posted May 28, 2021 Share Posted May 28, 2021 OK, I am wrong, just checked, even the 1939 G3WO only had one tap! how did they ever invented that! Cheers, Lex Quote Link to comment Share on other sites More sharing options...
Ron Posted May 28, 2021 Share Posted May 28, 2021 (edited) And it was still on the later G3WO's. Ron Edited May 28, 2021 by Ron Quote Link to comment Share on other sites More sharing options...
welbike Posted May 28, 2021 Share Posted May 28, 2021 Luckily they did away with it on later G3L's Cheers, Lex Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted May 29, 2021 Author Share Posted May 29, 2021 Thanks gents, perfect! I actually have the remains of now what I believe is the original petrol tap an balance pipe in the remaining ‘spares’ pile. I maybe able to salvage it...... Ron good to see you have some bling on you G3 (the brass inspection cover knurled nuts 😉) I am currently chasing down my next set of parts to get the engine wrapped up, mainly primary drive change, magneto chain and lower timing sprocket.....

flyingfleasteve Posted June 10, 2021 Author Share Posted June 10, 2021 Things have been a little slow the last few weeks with other non Matchless related jobs needing attention. I managed to get a few minutes this morning to take a little look at the missing items left for the build and I seemed to have confused myself with the dynamo, magneto and lower timing sprockets. Currently I am one sprocket short which originally I thought was the lower timing one, but now I am not so sure, maybe I have fitted them incorrectly? Quote Link to comment Share on other sites More sharing options...
Ron Posted June 10, 2021 Share Posted June 10, 2021 Well Steve, the mag chain sprockets will be the same size and teeth and the dynamo sprocket should have a slot for a key on the shaft. They all have different part numbers so the mag sprockets will have some difference between upper and lower. Ron Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted June 10, 2021 Author Share Posted June 10, 2021 Thank you Ron! So I have the dynamo sprocket correct, I just need to check if the sprocket I have fitted to the magneto is correct or whether it’s the lower timing sprocket…..

Ron Posted June 10, 2021 Share Posted June 10, 2021 The same parts are shown in the G3L parts list. Ron Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted June 11, 2021 Author Share Posted June 11, 2021 Thanks Ron. I am reliably informed that they are different depths for chain alignment. The mag sprocket is .576” and the cam sprocket .62” Best measure my existing to see what I have…… Quote Link to comment Share on other sites More sharing options...
flyingfleasteve Posted June 15, 2021 Author Share Posted June 15, 2021 A few more bits on order, hoping to get the primary side back together in the next week of so. A few other bits and pieces done but progress has slowed up since I started marathon training 😬 A small anorak question, what size/ thread are the carb control cable adjuster nuts? They seem quite Peculiar to me….. Quote Link to comment Share on other sites More sharing options...

welbike Posted June 16, 2021 Share Posted June 16, 2021 (edited) No, Marty Bratby once told me it's some kind of Model thread, very fine. Better call him to find out exactly what. Cheers, Lex Edited June 16, 2021 by welbike spelling Quote Link to comment Share on other sites More sharing options...
