Engine surges cleaned carb still have a surge problem

did you clean all the jets good sounds like it may be in the jets and needle part of the carbs

The carbs may need to be cleaned. Try running seafoam in the tank first and see if that clears some of it up. The slow jets may be plugged up inside the carbs. If the snorkel had been removed from the airbox, it could cause siminlar problems as well. have you changed the spark plugs yet? be sure to check out the Honda Magna forums for more info:

Its not your transmission because its not engaged in the gears you stated . The oil pump inside the converter is on but that would not cause this. The TCS better work in drive otherwise you'd have bigger problems. There are several different sensors that can cause this. Its best to bring the vehicle to a repair shop and have them scan the ECU for codes and if that doesn't work, scope out the vehicle to determine which system is malfunctioning.

If you leave gas in it during the off season, this is mostly your problem. It leaves residue in the bowl.and all the tiny holes in the carb. best thing to do is remove it and disassemble it. clean it with the best carb cleaner you can get. blow out all the holes with air and make sure they are free. Just a note. Some times you can buy a carb for a few more dollars than what it costs for a rebuild kit

Hi sndlys,
When the engine surges (we call it hunting) like that it usually means, the carburetor or the governor need adjustment. You have cleaned the carb. but did you clean or replace the air filter, and did you try to adjust the carb? Since it was running good before I doubt it is the governor. Try to adjust the high speed mixture screw by 1/8 turn at a time and waiting a few seconds to let that adjustment work it's way in the carb. Start by turning the screw out (counterclockwise) a few times. If nothing happens or gets worse turn the screw in (clockwise) a few times, but do not go less than 1 turn out from a lightly seated position. (turned clockwise until lightly seated so no damage is done to the seat or the needle screw) to prevent running in too lean a mixture to prevent overheating and possible engine damage. You could try the low (idle) speed mixture screw adjust a bit, but make sure you remember the position you started from whenever you any adjustment at all. I think if the carburetor is clean and the air filter is clean, also that there is a good fuel flow to the carb. you should be OK. I hope this helps out a bit.Get back to me if you need help. All the best and good luck. Denis.
