Getting a hesitation at WOT somtimes, power down goes away. Idles and now starts fine, have just done a de-carb. Original problem was hard starting and low idle fixed those problems with learning how to use the fast idle lever and installing new diaphram and fuel pump gasket and tightening and replacing a missing screw from the fuel pump housing, the boat would not start or idle very well but ran great at wot to 40mph. Now after having replaced those items and setting my idel mixture screws they were both out 8 turns from a seated position the engine has developed a hesitation at wot and slowed down a little, the hesitation only lasts for a few seconds the I power down and all is ok the idle screes are now 2-3 turns out and it does not stall going in and out of gear. The fuel in the boat is about 1 month old and the compression was ok when it was checked 3 months ago. Someone told me to now adjust the high speed idle screw, but I do not belive I have one. Any help would be appreciated.
<br />May try to go a little richer on my carb setting. The original setting from the previous owner was 7 to 8 turns from seated, it had idle trouble but great top end no lag. Now with all the changes and 2 to 3 turns out great idle no stall, but wot has a bogg or miss sometimes. Be patient we will get some answers from some very knowledgable people on this board.
