Yep, same with my 1888 B2200; my mechanic told me that some solenoid in my stock carb was bad, but he was going to be gone for two weeks, and he said he felt it was carb because when he added propane fuel it ran well. When I checked that dealer-only and expensive solenoid, it did seem to click and operate every time. So I figured maybe it was input to that very complicated carb, and I decided to go Redline Weber kit. When that didn't work well, took it back to the mechanic and by substitution they figured out that it was bad pick-up and ignitor in the distributor (he actually bolted-in his son's distributor to find this out). That was back in 2005, those parts weren't cheap, but good ever since.
So did the mechanic make an honest diagnosis mistake? Maybe. Maybe both issues had started. Anyway, I doubt that the stock carb would've laster another decade......
By the way, once my youngest needed 4WD and got her own vehicle (1998 4WD Pathfinder), that Frontier was a hand-me-up back to us, and Mrs. Cusser drives it daily, and I take it when I go out of town by myself.
