no, they were only there until i got proper crush tubes, it's about a 2 year old picPete. Can those be ordinary plastic cable ties securing your advance cable to itself? I never woulda thought they'd give you any peace of mind in an application like that.

Thanks for your reply Eric, very good info, I will post more pics in a bitWelcome to the forum. Why do you think it’s a 1980 80”? Do you have paperwork for the engine? If so what does it say? Some engines have a state-assigned number for one reason or another but often they contain at least one letter to identify the state concerned. Often but not always.
As Andy mentioned, those are not pre-70s numbers. Your R-H case is 70 or later if H-D or it could be AM. Did you remove the paint from the front of the case and if so what did you find? Photo?
And did you look for numbers under the cases? H-D Shovel cases usually have crankcase production numbers (CPNs) under both halves for 1974 and earlier. As of 1975 models the left case still had its CPN underneath but the R-H case had it inside the gear compartment.
Also about 1975 H-D began stamping extra ID on each case. For example A123. Some left cases have it near the CPN but most have it at the back. R-H cases usually have it at the back, just inboard of the oil pump.
Anything stamped on top of the cases near the rear mounting bolts? Depending on engine model and year some H-D Shovel cases have Hs or 7s. Photo?
Some AM cases also have ID in that position. For example some STD cases have several characters there which are an abbreviated version of their main ID number. Anyway, a photo of that area would be a good idea. Close-ups of the entire both sides of your cases may also help because I can’t tell a lot from your other pictures.
I have an "H" close to the rear left case mounting bolt
Re the heads, in your other photos the 66 looks like it is near the spark plug hole and it is probably part of a casting number. Front heads had 05 66 and rear heads had 07 66. These were introduced for 1966 models and they remained in use for some time.
On top of each head on the R-H side you may find date codes indicating the month and year the heads were cast. For example 4 75 would indicate April 1975. These codes are normally near the reliefs for the pushrod tubes but may be hard to spot so look closely.
Do I see a marking on the base of your front cylinder? If so what is it? In your other pictures it looks like one cylinder has casting number 16568-66? Can you confirm please.
The other cylinder may have casting number 16587-66? If so can you confirm. And what other markings does it have? Thanks.
