Move selector lever into position „?”.   07.2.2 la-100\/2       3\u00a0 \u00a0Check whether on vehicles with cruise control (Tempomat) the Bowden wire rests free of tension against regulating lever. Adjust Bowden wire with adjusting nut (1), if required. For this purpose, run engine. 4\u00a0 \u00a0Set engine oil temperature to 60\u201480 \u00b0C. 5\u00a0 \u00a0Check intake system for leaks. For this purpose, spray all sealed points with Iso-Oktan DIN 51 756 or benzine. A changing engine speed or CO value indi\u00adcates the presence of leaks. Attention! Do not use conventional fuel for spraying (unhealthy vapors). Pay attention to inflammability and do not spray on the red-hot parts or components of the igni\u00adtion system.   6\u00a0 \u00a0With the engine running, check whether throttle valve lever (3) rests against adjusting screw (68). 7\u00a0 \u00a0Check idle speed and adjust with adjusting screw (68), if required.   8 Check idle speed emission value without air injec\u00adtion. For this purpose, make air injection inoperative as follows (for (@) 1973\/74 nothing need be made inoperative): CD 1976 Pull off blue\/purple vacuum line at connecting point (arrow).   07.2.2 la-100\/3       V) 1976, model 114 Pull rubber cap (arrow) from blue\/purple vacuum line.   j[) 1976, model 116 Pull rubber cap (arrow) from blue\/purple vacuum line.   (us*) California 1974 Pull off red vacuum line at connecting point (arrow). @) 1975\/76 Pull off blue\/purple vacuum line at connecting point (arrow).   The exhaust gas for idle speed CO measurement on vehicles with catalyst, (T) 1976 and (usa) 1975\/76, is drawn off in front of catalyst at check valve (arrow) of air injection.   07.2.2 la-100\/4       For measuring idle speed emissions, open valve plate of check valve by means of a self-made wire hook. Connect exhaust gas hose of CO measuring instrument to check valve.   9 Adjust idle speed emission value without air injec\u00adtion. For this purpose, adjust both adjusting screws (arrows) uniformly. Screwing out = richer Screwing in = leaner Accelerate for a short moment, check idle speed and idle speed emission value once again and readjust, if required.   10\u00a0 \u00a0 Reattach vacuum hose for air injection (air injec\u00adtion operating). The idle speed emission value should now be below the previously set value. 11\u00a0 \u00a0 Adjust vacuum governor. Run engine, pull off vacuum hose (64), set to specified speed by means of an adjusting screw (63), attach vacuum hose. Attention! When loosening counternut, apply counterhold to diaphragm rod. Engage driving position on automatic transmission, set to specified speed by means of adjusting nut (61). Turn power steering to full lock and engage air condi\u00adtioning system, engine should still run smoothly. Readjust speed, if required.   07.2.2 la-100\/5          <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_crdt_document":"","footnotes":""},"categories":[32,27],"tags":[],"class_list":["post-2461","post","type-post","status-publish","format-standard","hentry","category-carburetor-fuel-pump-throttle-linkage","category-m110"],"aioseo_notices":[],"featured_image_src":null,"author_info":{"display_name":"mackuz","author_link":"https:\/\/mbci.mackuz.ovh\/index.php\/author\/mackuz\/"},"_links":{"self":[{"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/posts\/2461","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/comments?post=2461"}],"version-history":[{"count":1,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/posts\/2461\/revisions"}],"predecessor-version":[{"id":2462,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/posts\/2461\/revisions\/2462"}],"wp:attachment":[{"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/media?parent=2461"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/categories?post=2461"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mbci.mackuz.ovh\/index.php\/wp-json\/wp\/v2\/tags?post=2461"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
