4L1-00 carbs to use.<\/p>\n\n\n\n<p>Out of all the carbs, and spares, and boxes of bits which I have, I found precisely 1, (one), genuine LC carb top and that is missing the 45 degree angles cable guide.<br>Genuine carb tops seem to be made from unobtanium, and the 45 degree inserts are very expensive, (for what they are), largely driven by supply and demand i should have thought rather than profiteering.<br>It would be useless to invest the money in the angled guides if I don&#8217;t have a pair of carb tops to go with them. ebay was bare, so I needed another solution, beyond just using two of the many many aircooled RD carb tops I have along with stacked adjusters or some copper piping, as I have in the past.<\/p>\n\n\n\n<p>While browsing ebay for parts, I came across some extremely cheap carbs marked&#8230;<br><a href=\"https:\/\/www.ebay.co.uk\/itm\/154015026436\">Carburettor Carb For Yamaha DT100 RT100 DT125 RT180 DT175 BW200 YZ80 YZ85 Carb<\/a>.<br>or<br><strong>Yamaha DT125 1979-198 Carburettor Carburettor Carb Complete DT 125<\/strong><br>&#8230;which seemed to be a Mikuni 28mm copy.<br>Clearly made in China, they did have tops with a angled cable guide, so I gambled and bought a pair, reasoning that even if they were useless, I could rob them for parts.<br><\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-1 is-cropped wp-block-gallery-2

an inline fuel filter, which given the state of my fuel tanks may be useful, and 2 lengths of pink fuel drain pipe.<br>The tops, for which I bought them, fit onto the LC carbs, but the guide tubes are hard fitted into the holes rather than retained with a circlip like the real thing.<br>They are shorter than LC carbs, so the slide is useless, the needle is a slightly different profile to a standard LC one, and the float bowls have holes, pipes and jets in the wrong places to be of any use.<br>The floats might work, but the float needle seat is shrink fitted to the carb body so no o-ring and retainer.<br>i&#8217;m not going to trust the main jets, and the pilots are of a totally different design.<br>The choke is a bit stiff, but fits onto the LC carb body, and appears to seat properly.<\/p>\n\n\n\n<p>So all told, buying two of these horribly low quality items was probably a waste of money, however I DID get the two tops, and a pair of in-line fuel filters, at a cost less than one LC carb top cable guide, so I have something which will at least LOOK right on the carbs when I rebuild them.<br>I&#8217;m also going to use the choke mechanism, and of course I have a pair of brand new float chamber gaskets which fit fine.<br>NOTE: i&#8217;ve just checked ebay again for these things, and the price has more than doubled, (from \u00a315 to \u00a338), in the past 2 months since I bought them, which throws the whole VFM equation out of the window.<br>Still, I hope this evaluation and pics of the inside helps someone.<\/p>\n\n\n\n<p>Now to cleaning!<br>I set to, scrubbing with a toothbrush and a paraffin bath, but made little progress, although I did manage to remove much of the surface filth.<br>I don&#8217;t have a vapour blaster&#8230; and funds are running low for just sending stuff off for blasting, as much as I&#8217;d like to, so I made an investment.<br><br>i bought an ultrasonic cleaning bath.<br><br>Honestly, I wasn&#8217;t expecting much, and initially, that&#8217;s exactly what I received for my carefully researched \u00a345.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-3
