    175 2 stroke wont rev past 2k

    removed fuel qds and blew through accessible lines. no obstructions removed carbs and manifold to inspect reeds. no issues noted. going to tear apart that bottom carb for a 3rd time and look for issues. also considering moving it to the middle to see if the issue follows the carb. might do...

    agreed. do you have any thoughts on the reeds?

    175 2 stroke wont rev past 2k

    Not trying to ignore ya here.based on your comments I placed a see through fuel line between fuel pump and carb ( downstream of qds) and fuel flow looked great. So this to me says the lines/qds are clear. Should rule out entire system pre carbs. The reason I said "I assume" would be due to...

    Spent some time adjusting idle mixture screws. Started at 2 turns out then went in until idle got worse then backed out 1/2 turn from there. Bottom two mixture screws did not effect idle even when screwed all the way in.... Verified once again had blue spark jumping 3/8 to 1/2 inch on...

    Put clear line between fuel pump and carburetor. Looks good very few air bubbles on initial start. Then after one minute zero air bubbles.

    Does anyone know why both my meters/DVA wig out when i try to measure coil voltage? one shuts off the other moves so fast i cant read the numbers.

    I have spot checked the connectors and fuel lines (they are the grey kind). No deterioration or debris found in the lines are filters. I am buying a section of clear fuel line on the way home to install to check for air bubbles to hopefully rule that out for good. Drained the big fuel filter. I...

    Water test results Outer box 1000rpm Low speed 212 High speed 130 Inner box High speed 125-130 Low speed 213 Bias 5.5 All this seems to be in spec. I can't get it to 3000 rpm in gear and I don't want to rev in neutral to 3000 so that is all the info I have to go on. I am unable to get...

    Possibly a Bad Stator

    Yellow black wire is the kill circuit. Seems like your on the right track to a simple solution.

    Possibly a Bad Stator

    You also have to test the voltage using a dva. The resistance isn't the whole story. No spark could also be switch boxes

    Ok guys here's the results following stator dva at cranking speed. Per manual Stator high speed (red wire) 400 rpm 25-50 volts With spark advance box plugged in 3.x volts Without spark advance box plugged in 17 volts Both of these are below spec one obviously more than the other. So here's my...

    I changed both. seems weird I am now having the same issue with the low max rpm but have spark on all cylinders (i changed boxes because I only had spark on one bank)

    I will check the stator high speed later this week. I have a DVA but I have been having trouble getting it to work with my multi meter. Need to get that figured out Would an intermittent stator high speed toast a switch box? Wondering if that is why my switch box went out originally and a...

    Could it be stator high speed winding? Just because it has good spark at idle doesn't mean it has good spark at RPM. is there anything else that can cause bad spark at RPM? I checked resistance on the stator windings earlier this year and they were in spec but I guess I should check again.

    I checked most of those things when I initially ran into this problem. switch boxes was the problem then so I struggle to think its fuel now. I do have the grey lines too. I will check the qd for build up, had this happen on a kicker before only found that by luck. earlier this season: new fuel...

    i have been considering doing this. what should i set timing after the box is removed? stick with the standard 0-9 ATDC at idle and max 20 BTDC?

    Checked timing today in garage. While cranking engine 9 def atdc While cranking with throttle advanced 19 btdcthis is with white wire to spark box disconnect. Didn't seem to change when I plugged it back in? Also checked spark again with my new cdi adjustable tester. 3/8 blue spark all day long...

    Cleaned carbs. Spotless inside. So that doesn't seem to be the issue. Will be checking idle and timing advance next.

    175 2 stroke wont rev past 2k

    Symptom persisted today on a test run. Components would have been cool to start test run. So I don't think it's a issue. If it's not spark what else could cause my symptoms? Could the advance module be limiting timing?
