I have a 87’ Yamaha Phazer Deluxe I picked up a couple years ago that I’m trying to fix up as a backup sled and for ice fishing. Sled is in decent condition but I’ve run into numerous problems. Initially it was running on only one cylinder. So I have replaced the plugs, cleaned both carbs, tested plug wires, replaced the gas lines and did a compression test on both cylinders in the past couple days. Plugs were both wet when fired up, compression on the clutch side cylinder was 80psi, and 100psi on the other cylinder. Carb on the clutch side was corroded due to a bad gasket and bowl cap. That has been corrected. However, after firing up the engine, I found it is still only running on one cylinder. Engine has decent compression, gas and good air flow. Am I missing something? Has anyone run into anything similar? I’m thinking could be an electrical issue, any thoughts?
