I'd start by making sure the air filter is clean and then get any info available regarding valve cam clearances. Depending on the hours and milage on the machine there may be the need for some maintenance.

Testimonial: "Hi Ted. Regards from Namibia / Southern Africa. Thanx for your advice. Trying to be a perfectionist, may I say, all the Basic maintance like air filter clean, Throttle Body Filter taken out already etc are done. Tell me about the fuel tank, is there a filter inside aswell...?"

    And Good Day from Vancouver Island Canada.
    Motorcycles rarely (Never that I know of) have a filter inside the gas tank. It is not uncommon for there to be contaminants (rust, water) inside the tank. Fast test is to shut off fuel valve, disconnect fuel line, hold glass or plastic container to catch fuel, turn valve on and get fuel sample, valve off so you don't spill, then check the fuel. if it is clean and flowing freely, that will not be the problem.

    Afterthought:
    I have a KLR650 and a grandson in Johannesburg.
    Would bringing riding a similar machine there be a realistic adventure?

Blower bogs down and kills at full throttle


Check the following, then clean or replace:
  • Fuel Filter - Located IN the fuel tank
  • Spark Plug
  • Spark Arrestor - at muffler port, creates resistance of exhaust flow, engine then bogs
  • Carburetor - may need a rebuild kit
Then watch this...

and...

Jet adjustment


The carb has an L screw, an H screw and an idle screw, both screws are fuel, not air screws, the L screw will increase the fuel mixture from idle to half throttle, the H screw will increase the fuel mixture at full revs, this will also govern the maximum revs the saw will do, it is very important you do not exceed the manufacturers recommended max rpm, if the saw will not rev clean up throught the revs, increase the L screw bit at a time until it does.

32LC trimmer will start and idle but bogs when trying to advance throttle. I can not get it to rev up. I put fresh fuel mixture in it, changed the spark plug, cleaned air filter, even purchased a new...


Did you try cleaning the carburetor before installing it? It may have factory oils and greases that are obstructing fuel flow.

If it runs fine at idle but bogs down when reving, then you are either not getting enough air or not getting enough fuel.

Have you notices any black smoke from the exhaust when you try to rev it? If so then you are running too rich and aren't getting enough air. You may want to check the path of air travel for other restrictions.

I Have a Ryobi Trimmer. I cleaned out the carb and put it back together but forgot the High and Low needle settings. I have got it to start but am having trouble tuning it. I have put a carb kit in it and...


adjust the needles both all the way in until they stops. unscrew both 1 1/2 turns and start engine. slowly accelerate and if it bogs down unscrew the HIGH SLOWLY until full speed is gain. some times you have to unscrew a little the low speed too. is a matter of playing with it. be patient you will get it. if you are still having problems you may have to take the bottom of carb. out and make sure the gas inlet needle is letting pass gas into the carb. chamber.

Engine bogs down when speed is increased.


Ok I have r Royobi Tiller (30CC Gas) And last year it ran fine after rebuilding the Carb. This year it was "hard starts" Idles fine, (Tiny whisps of blue smoke in exhaust with correct ratio) Even seems to run better with the choke "on" but still...at idle only. as soon as I touch the throttle...its bogs down in tune with how much gas I give it. Little throttle? Little bog down, Little more throttle? Almost stalls, a normal throttle rev? it stalls dead! Then starts right back up again in 1 pull and idles fine again!? WTF? So after cleaning a clean carb again, (twice) and seeing no change I thought I'd go look at the original diaphragm and compare it with the rebuild kit diaphragm (which is the one in the carb.) And guess what? The replacement has a larger rivet by a factor of "2". So basically it was flooding the carb, I bent the needle tang down, better but no cigar. But I could rev it half way now. A second disassemble to bend it yet a bit further and Vrooom vroom vrooom ****! So check your needle valve even though you think its 100%. (Especially if you rebuilt the carb with a kit!)
