Last year I had several cases of the carbs on my T9.9 blocking up requiring a teardown and cleaning
the jets with a fine wire. I took several steps this season, which appear to be helping. I replaced an old rubber fuel line from the tank to the engine. I installed an inline 10 micron water separator fuel filter. Lastly, I now only buy higher octane fuel, not for extra power, but perhaps there are more additives in there to keep the fuel stable (10 % ethynol). Of course, I continue to use stabil in the tank. So far this season, no starting problems.
However, I do have another problem with the engine
acceleration lagging after engaging the gears to go in forward or reverse. I have to crank the throtle handle a good amount before the engine picks up speed. This occurs on either a cold or
warm engine. Otherwise, the engine is running fine. Has adequate power and idles ok. Any ideas
on what is causing this lag?
