318 or 360 Roller Swap
I'm in the same boat. Lately I've been very tempted to dig into one though. Harms wants $400 to restore one, which is more than I'd like to spend but probably worth it. There are also several sources for remans in the $200-225 range, but who knows what kind of bag of parts you'll be getting.
Well, here is the beauty of going through Scott Harms for your carb.
He does really nice work
It WORKS!
I’m sure he has some spare parts.
IF you decide to get a TQ for experimentation, talk to Scott directly and just ask for an early big primary model. Not the first year of the carb.
The larger primary carb works best on modified 340’s and up.
Cut the cheaper AFB rods down 3/4 of an inch and re bend to fit the TQ. Be accurate at the bend point. Grab the secondary tuning tool. It just makes life a lot easier to tune the secondary opening point with the tool. Do not cap the bowl vent on the top part of the carb.
Do not get frustrated. It’s a tricky carb until you get to know it a little and then you realize, it ain’t that tricky. It has settings that need to be measured and adjusted. Real close is good enough for most settings.
If you want to give one a shot and rebuild it yourself, you may need to bush the throttle shafts. That can be a pain. Otherwise, there not a hard carb to rebuild at all.
Just have fun and tinker with it.
