As you probably all know (and I am learning), the ?49 A7 longstroke has the tappet guide blocks located in the crankcase; the exhaust tappets are located in a dual tappet block centered between the two inlet tappet blocks. The single inlet blocks are removed with difficulty, but the centre dual block drops out when the case is split. Well, my project A7 longstroke had the case split before I picked it up and this dual tappet block, along with the exhaust tappets, is missing.
I?m waiting for my ?49 A7 Parts List to come in the post, since it is specific to that year, so I will be able to correctly identify the tappets/block. The dual block (according to Draganfly, the part is listed as 67-1024F ?tappet?) is available from them on exchange only; since I don?t have the original block the price of 14+ GBP jumps up by an extra 20 GBP since they are in limited supply. In the meantime, I?ve tried to locate the dual block and tappets elsewhere, but with no luck (much of the time is spent convincing parts rep that I really know what I need, and that it is different from later models!) I would appreciate any advice you can provide, alternatively to just coughing up the extra 20 pounds.
