Brand new 1776 engine is stumbling/weak

[Alstrup]

Alright.
It is almost certainly not the carbs fault, its the combo. You can most likely make it work, but it will take some work.
Need the EXACT specs on the engine. Which heads, CR cam, rockers Then we will see what we can do.

PS. just found his website. Judging from the parts used I´d say it is either a Scat or Empi/Engle cam and most likely a set of Empi GTV heads. But it is speculation. We need to know.

Ok. So I have some information.

The heads are FPD 40mm intake 35.5mm exhaust.

The camshaft is an Engle 110 and the rocker arms are 1-1 racial.

Glad to know the carbs are likely not at fault, however when I talked to Jeff at the Kaddie Shack he was certainly not a fan of these specific carburetors.

Thanks!
