netley Posted April 15, 2017 Report Share Posted April 15, 2017 Hi, Just giving the carb a good clean. It's an Amal L2627 410. The only info on the correct jets etc. for the 349 are for an L2627 216 and I have slightly different ones. Info taken from this site says; Amal carb as per MH359 manual Make;Amal type;L-2627/216 Mine; L-2627/410 diffuser diameter;27 27 Main jet;145 150 Low speed jet;20 20 Gas valve;no.4 ?? what's this ?? sprayer;107 106 position needle; 2a (2B1) Middle groove of 5 2B1 It looks like I can get all I may need direct from Amal uk. Should I go with what the manual says or stick with what I've got as it's a different model? The slide looks worn so I shall replace that. Thanks for looking.

suzuki250 Posted April 15, 2017 Report Share Posted April 15, 2017 how well does the bike run? If it runs fine, don't mess with it Quote Link to comment Share on other sites More sharing options...
2stroke4stroke Posted April 15, 2017 Report Share Posted April 15, 2017 The gas valve is the slide. You have a small difference in needle jet (sprayer) and main jet. I was typing this as suzuki's reply came in and was about to say see how it runs before changing anything. But I am not familiar with the difference in carb types though the numbers might indicate that yours is intended for a four stroke, but as it has a pilot jet then perhaps not.

netley Posted April 15, 2017 Author Report Share Posted April 15, 2017 Cheers, The bike doesn't run but has done briefly, split inlet rubber won't be helping. Trying to ensure the carburation is correct first. Neil Quote Link to comment Share on other sites More sharing options...

Neil Hi Neil, I think that example you posted is actually a 416 not 216. Regardless, here is a couple of exploded view diagrams I have found for 349 carb's. The 1st one is for a 406 carb with a part number of '5162.00101' possibly one of the 1st 349 versions, the 2nd pic is for a 416 carb with a part number of '5162.00104' definitely intended for models 51M24424 and upwards and more likely suited to the last of the 349's, such as 349/4, MH 349 and 350. Hope this info helps. PS: Can only upload the 406 in this post, the 416 will be in next post. 1 Quote Link to comment Share on other sites More sharing options...

netley Posted April 16, 2017 Author Report Share Posted April 16, 2017 Thanks, Those are great ! I have priced up replacing all the jets, gaskets etc. and it comes to 46 GBP (76 Austalian dollars). I recentley re-built a Bultaco which had the wrong carb on and replaced it with a new Mikuni from the same company, which works great. A new and ready jetted to suit the Montesa Mikuni would be £157 (259 Australian Dollars). Seeing as the one I have is getting on a bit I'm thinking of doing the same. Any thoughts?

netley Posted May 7, 2017 Author Report Share Posted May 7, 2017 Had the OKO 26mm carb delivered Friday. It seems most of the wiring is shot so had to do a few temporary fixes. Wouldn't start checked everything then finally put a new plug in.
