I...Thanks again William; that's super information. I wonder if those camshafts were original? They are of course VAR 1016 camshafts. 0.40 mm was the normal checking clearance for timing for all the cams. Perhaps the 1016 cam acually pre-dated the 1600? Interesting if it did!Paulhttps://www.blogger.com/profile/17607706475235226890noreply@blogger.comtag:blogger.com,1999:blog-34267493.post-19750025284209977802007-03-03T15:29:00.000+01:002007-03-03T15:29:00.000+01:00An unrestored never raced '68 1300HFSpeciale just ...An unrestored never raced '68 1300HFSpeciale just sold on Ebay had a accompanying factory letter stating 113Hp at 7000 rpm.

The Simca Abarth 2000 used 58(!) chokes to reach over 200Bhp. Poor comparisson but 42 with maybe a 33 venturi might work. Any smaller and the original 35's would flow better.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-34267493.post-76166991706642217622007-01-04T00:16:00.000+01:002007-01-04T00:16:00.000+01:00Thanks for the comment William.

After all when Triumph prepared the Spitfire (1147cc) for race use, they used 45mm Webers, so it should be possible. I would think that your chokes should be perhaps 33mm though or even 32mm.Paulhttps://www.blogger.com/profile/17607706475235226890noreply@blogger.comtag:blogger.com,1999:blog-34267493.post-58719550395067370662007-01-03T20:44:00.000+01:002007-01-03T20:44:00.000+01:00Interesting stuff about the Solex 40mm for the HFR...Interesting stuff about the Solex 40mm for the HFR 1300. 34mm choke. These carbs are undoubtedly impossible to find. My tuned 1216HF is using Dell Ortho 35s at the moment but i wish to experiment with larger carbs. What do you think of the Idea of making smaller 34 venturis to put in the (easily available) solex 42's? This is 2mm larger but the smaller venturi should compensate.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-34267493.post-23468141866297368882006-12-20T13:29:00.000+01:002006-12-20T13:29:00.000+01:00Thanks Neil.

The Dell'Orto has I believe a superior pick-up circuit and is much better built with I think bearings for the spindles in place of Solex's running them directly in the metal of the body. I do not agree though with using the DHLBs on 1600s; 35mm is too small and tragically Dell'Orto never made them in larger sizesPaulhttps://www.blogger.com/profile/17607706475235226890noreply@blogger.comtag:blogger.com,1999:blog-34267493.post-66194688338299350962006-12-20T11:04:00.000+01:002006-12-20T11:04:00.000+01:00Paul, lots of interesting information here, how do...Paul, lots of interesting information here, how do the Dellorto DHLB 35s compare to these, I realise they were an aftermarket option and not used by the Lancia competition department, were they much better made than the Solex variants?
