I have a Wright Sentar with a Kawasaki 25HP FH921V-BS07 with a Nikki that is labeled 150037048 266401 - although the Kawasaki documentation states that I should have a Nikki P/N 621266. I have not been able to find any documentation on the Nikki carbs. I also suspect that the shut-off solenoid is not working. Can it be bench tested?
In any case, the engine has always been had to start - from day 1. It had gotten so bad that I had to pour gas into the carb to get it to start when cold.
Recently I had the cover off the engine exposing the fan to check the resistance of the coils while hot. One thing lead to another and the fan broke and I overheated the engine. This created a crack on the block behind the starter and a huge backfire was heard when it shut down. Backfiring is nothing new - it always backfired when I shut down.
With the crack in the block, oil smoke billowed from the engine and oil was spraying everywhere when I stopped. While on the way back to the garage after the fan broke, the throttle had little to no effect on the speed of the engine - seemed odd at the time, but I assumed the cable was slipping what with all the oil that was spraying around, or that something had come un done.
In the process of repairing the block (with JB Weld - it worked great, so far), I decided it was time to disassemble the carb for cleaning to correct the hard starting.
All is now well. It starts almost immediately, but I still don't have any throttle control. I have confirmed that the choke and throttle butterflies are operating as they should, but I still get no change in engine speed with throttle movement. I'm at my whit's end, PLEASE CAN ANYONE HELP.
