Ural Issues

Friday - Today's task is trying to get the Ural back on the road. It would start and only run if the right cylinder choke was on. And even then, it was running really lean. I pulled the right carb and dropped the bowl it had gas and was clean. I reinstalled the carb, moved the petcock to prime and fuel started flowing out of the bowl vent. The float valve wasn't sealing.

Yesterday, I started installing an HF antenna mount on the rear ladder of the RV. A week and a half ago, I picked up an HF radio, antenna and cable from Ham Radio Outlet in Plano, TX, but they didn't have a ladder mount. This was shipped to the RV park and it arrived the day before we left. I should've just ordered it from Amazon. Maybe. I ordered a telescoping mast to install the StarLink on and Amazon claims that it'll be delivered today. It hasn't even shipped yet.

Later - I pulled the right carb and the needle valve was sticking due to a buildup of varnish on the needle valve. I cleaned it and reassembled the carb and the Ural started and ran sort of okay. I took it for a ride and it really felt like only one cylinder was running. The EGT for the left cylinder was reading ambient temperature and after a mile of riding, the left head was barely warm.

Saturday - Bad news. The left cylinder is not working. The needle valve on the carb was all gummed up and not able to open so no fuel. After that was fixed, I swapped the plug wires and it still ran the same. Operating the throttle on the left cylinder did nothing. The valves are operating correctly. So the next step is to pull the head.
