1946 2N w/ 1948 8N engine (front mount distributor) and 12volt conversion (6 volt coil) surges under finish mowing load.
My impression is a fuel issue, as tinkering with the carb helps, and the start is quick and idle smooth. However, when idling and I screw in the mix screw all the way, the engine doesn't falter like the FO4 manual says it should. Is it possible the end of the screw broke off in the carb?
When the engine was installed 6 years ago, it appears the mechanic used a squeeze tube of gasket material between the carb and manifold. I say this because it looks like tar is dripping out of that joint. I tightened the bolts that attach the carb to the manifold and perhaps the form a gasket material is wearing out because the bolts had some play.
Over the years I've seen how a lot of guys on this board misdiagnose a fuel problem as electrical. I want to make sure I'm not doing the opposite. Thanks for reading!
