Hello all,
I am seeking some wisdom on an issue I have been trying to nail down for some time...
I recently purchased a '99 Yamaha C50TLRX 2-stroke and mounted it on my 15ft Javelin bass boat. Engine runs fantastic at idle. When on the water and trying to reach plane, the engine will begin to shudder / hiccup like it is not receiving enough fuel, or maybe overheating causing the limp mode to kick in.
A local mechanic told me based on the symptoms I described that it was the high-speed needle on my carbs and that he would rebuild them for $75/each.
I have tried to figure this issue out for sometime but have had no luck and decided to post here.
Here is a list of things I have checked:
- Replaced prop to eliminate the possibility of an off-center hub,
- Taken carbs all of and cleaned each with carb cleaner (looked very clean inside)
- Combed through the cooling system (impeller, water jackets thermostat) to make sure I am not overheating and causing the engine to be in 'limp' mode
Any advice would be greatly appreciated!
