    How is this possible

    OK here are the results as I just made it up on the mountain today. cyl #2 106 comp, 1/4" + spark gap. cyl # 4 106 comp, 1/4"+ spark gap. cyl #6 106 comp, 1/4"+ spark gap. cyl #1 106 comp, 1/4"+ spark gap, cyl #3 109 comp, 1/4"+ spark gap and cyl #5 106 comp, 1/4"+ spark...

    Makes perfect sense just such a pain to haul and launch every time I make a change or repair to test. Guess that's just the nature of the beast.

    Why not ??

    How is this possible

    Can I do something like put steel wool in the center of the prop to create resistance on the muffs ??

    Thanks for the input I have picked up the gap tester and will check both the spark gap and compression on my next trip up. Will let you know what I find.

    Sorry all for my computer illiteracy but the video is now available on youtube labeled as 1988 merc black max 200 I know you should not run in gear at high rpms on the muffs but getting desperate

    How is this possible

    Runs like a striped ass ape on muffs but won't accelerate above 1200 rpm in the lake. Have checked compression, spark, float level, vacuum leaks. It is a 1988 merc black max 200 2 stroke. I am in big bear altitude is about 6500' already have high altitude jets prop is a 19 pitch, fuel lines and...

    High altitude

    When running on muffs in neutral it rev's up just fine but not with a load on it.

    High altitude

    That's what I thought however I can't get beyond a fast idle it just stumbles and die's like it's starving for fuel I'm thinking sucking in air with fuel or improper float adjustment. What do you think ?

    High altitude

    I have already ordered the replacement jets but being somewhat of an oldschool automotive mechanic it doesn't seem to me that the jets should cause this acceleration issue. I hope it is just sucking to much air at the bad fuel can connection.

    High altitude

    Have already done both I have replaced both the stator and switch boxes compression is good on all 6

    High altitude

    I was able to find the jet info However do any of you old pro's know if the altitude would cause the acceleration issue ?

    High altitude

    Outboard is a 1988 Black Max 200 HP 2-stroke serial number 0B304145 took it out for my first time today and it will not accelerate it lugs and dies, idles perfectly we idled around for about an hour and a half using 6 gallons of fuel. I know the fuel fitting at the tank does not have a perfect...
