    I had the same trouble but cleaning the carb didn't fix it. I took the float out and shook it. Something was inside so i replaced it. Problem solved.

Serges up and down and stalls after a fes coleman maxa 5000 er plus


Hi mxdidit,

Surging is generally caused by carburetor problems. Squirt some carb cleaner in it and see if that helps it at all. If that helps but does not do a lot, then the carb probably needs to be rebuilt. The carb could also just need some adjusting. Check for fuel leaks around the carb and also be sure the air filter is clean.
Good luck.

Hope this helps. If it does, I'd appreciate your vote. Thanks,

Coleman 5000 watt generator Tecumseh 10 hp engine. Surging r.p.m. Carburetor has been gone through 2 times, and still not correct. Any information will help!!!


it's running lean.....try resetting the choke partially when it begins to surge.....not completely closed, but enough to richen the fuel mixture (that's all a choke does btw..)
if that helps or clears the problem, your carb is outta whack.....cheaper to buy a new carb than keep taking back into the shop.

Coleman Powermate 3000 surging


Check your air filter to make sure it is clean, especially if the gen. has been run in dirty, dusty conditions. Make sure the gas tank vent is not clogged.

Also, pour some combustion cleaner into the carb. through the air intake to clean the carb. It sounds like it is starving for gas.

Hope this helps.

Surging 5000w Coleman Generator


I had a Colman that only surged when it had a large load on it. ConsumerReports.org says that some Coleman generators just can't hold a constant voltage. Hondas are expensive but very good,.

Coleman 6875, Does it have an auto idle???


Hi,
If you've got an auto idle function you'll also have a switch somewhere to shut it off, so look for that first.
Engine surging is almost always a problem somewhere in either the air cleaner or the carb. Check the air cleaner, if it's not dirty take the bowl off the carb and look for dirt in the bottom.

Carl

No electric power generated from my Coleman Powermate Maxa 5000W.


the gensets on coleman generators are definately nothing to brag about but i would start by checking the windings and make sure the brushes have a clean armature to ride on

Coleman generator OHV3000


The carburetor is probably clogged up. Mix a bottle of carburetor cleaner with the gas to see if that would help. Also check/replace the fuel filter.
