A65L carbs

[wardy]

Hi folks

A65L will start and run but not well so am checking the carbs. Carbs are marked 930/56 and 930/57 but I don't see them listed anywhere in the Haynes manual. Needle jets 105 (should be 106 I think), main jets 200 which I think is OK. Any info appreciated. Thanks!

Depends on the year of your lightning,am early bike 1966/67 would have had monobloc carbs fitted 389/228 and 689/228 with 270 main jets and 106 needle jets.. You have concenyric carbs  so 1968 they would be R930/21 and L930/22 with 190 main jets and 106 needle jet. from 1971/72 they had R930/70 and L930/71 with 200 mai jet and 106 needle jet. This info is from the AMAL catalogue. for all bikes. I don.t know what bikes those carbs you have are for but the correct carbs will have bore size of 30 mm.

Thanks Bob - they look right in terms of diameter etc. so will change the needle jets to 106 and see how I get on!

Primary circuits are always a problem unless you know how to clean them properly. See YouTube Amal Service.
