Hello All.... I'm helping a guy out with this new to him Speedster. Both engines start and idle fine, when you try to accelerate the miss and will not rev. Compression is a bit north of 135psi on all cylinders. I pulled the carbs off the port engine found a couple of issues. Pop-off is at 46psi. I noticed fuel dripping into the barrel from the main jet area on both sets of carbs. That's whyI pulled the carbs. They were recently rebuilt. Installed the carbs and no change. I did a spark check and it looks like the PTO cylinder is getting intermittent spark when you try to reve the engine. I checked the Starboard engine and it does the same thing. I've never worked on one of these so be gentle.
I say the issue is definitely spark.
Just a note, only ran the engines a few seconds and the water hose was not connected.
