This is actually for a 4 stroke gas carb, but I figured this might be the best spot to ask since someone in the vintage karting world might know or have some ideas. I have a large bore tilly HL and I want to use velocity stack/air horn on it. I never payed attention till the other day when I noticed this thing is a way bigger bore and bolt pattern than the HL's I have on my 2 stroke kart engines.
When searching around for flanged stack, I saw a reference to an airhorn (I think it was a vantech) that just stated for the big bore carbs on a certian mac and it was 2 bolt not hte 3 bolt, no measurements though. Just wondering if anyone would know of one that might fit this thing so I know what to look for.
Here is the bore pattern:
What I am hoping to find (something like the 2 on the left. I can modify that air cleaner assembly on the right by opening up the intake hole and redrilling for the bigger bolt pattern, as its for the smaller pattern, but it not really the look I want and it would be easier to force choke a stack if needed)
