TMR member supply shortage with 4-month lead time
VM14/147 O-ring and nozzle guide have a 4-month lead time…. That means February next year. Now I’m in a bind…. I checked everywhere but no one has them in stock, so I have no choice but to adapt existing products. If you know the sealing clearance of the O-ring, you can adapt it.
TMR float level (oil level) is 12mm ±1mm I pulled out this manual for the first time in a while. The float level had been changed, so I reset it to standard.
Adjust the synchronization with just the carburetor. Being able to adjust forced open/close on the unit alone is really convenient.
You can work comfortably without worrying about oil temperature
Proper preparation before starting
First, change the engine oil and filter to get it in fresh condition.
The spark plug condition looks questionable too, so I’ll replace it with a new JR8B. Then with the plug out, I’ll do some good dry cranking to circulate the engine oil thoroughly.
Since I’m reusing most parts and only replacing the minimum O-rings, I honestly didn’t have high expectations, but it’s running better than I thought. I’m somewhat relieved (*´ω`*)
Adding a throttle holder stopper
This is a pretty old design Yoshimura throttle holder. This product doesn’t have a stopper, so I’ll add one with custom machining.
This way it looks simple without a lock nut.
Without a stopper, “Adjusting throttle play by balancing the accelerator wire OPEN/CLOSE” becomes very difficult to adjust and lacks that satisfying click when releasing the throttle.
In short, with a stopper, “You can adjust play on the OPEN side only” The CLOSE side is just a safety backup, which makes it easier to understand.
The reason lock nuts are often attached to stopper bolts is “To adjust according to the throttle sleeve winding diameter” If the winding diameter is fixed, matching the length and using ultra-low-head bolts looks sleek
For future reference, it’s good to check the winding diameter too. Currently it’s 32φ.
Anyway, the engine started, so I’m relieved (*´ω`*) To be continued
