Hello everyone, i have a few questions about my 92 Yamaha 200hp TXRQ outboard. Im a newbie to 2 stroke outboards.
My problem is: After running 10-15 mins UNDER LOAD, if i decell to 1600-1100 rpms, i notice what seems to be a missfire, and running on 5? clys.
I have replace spark plugs,Rebuild the Carbs,replace water seperator, replace fuel pumps.
** the carbs were like new, as the original owner had them done last year but i still went through them. The Solec manual has a few adjustments for the neelde valves,a depends on wich 200 it is, how do i tell wich 200 i have,** it states on 1 model the port and star board will have different settings, and why ? and what are the engine variations?
** the spark plugs had a wierd issue. The port side was "wetter" than the starboard side....Could this be from the carbs not being properly adjusted originaly? and if not what could cause one side run richer or leaner? I could under stand if it were a carb it would be either the top middle or bottom 2 plugs with a difference or a fuel delivery issue all the plugs would be out of normal. I can only come up with a t-stat possiblity but a temp gun reads only 5deg differance between port and starboard .
The Solec Manual is Very Vauge on operation, and i would rater learn about the system operation before going at this blind, is there a factor manual available that has just the 200hp model instead of the 2-300hp 2 & 4 stroke engines. (it just seems to jump around alot)
Thanks in advance for your help!
