well as u know i picked up small little suzuki for my daylie it has 1.3 block and 1.6 head

was going great when i first got it lots of power after a few times off road it starting coughing spluttering i changed the fuel filter and it started going good then it went bad again so i thought it was dirty fuel droped tank filtered all the

fuel and its basicly the same as it was when you put your foot down there just seems to be a lack of power now untill revs get up .. when i first got it i could drop Rubber easy .. now after looking at the whole fuel system i think it could be carby maby dirty any ideas what i should look at after i take the carby off .. i also think it could be the electronic fuel pump messing up its quite nosy now any as it was not mounted properly and was just hanging getting whacked around when i first got it .. any way to test the pump any ideas thanks guys

Take the jets out, give em a clean (Scratch around inside with a needle of blow through with a compressor). Get some carby cleaner/throttle body cleaner and spray everything in the carby.

yes it is

Let's hope it's not the carb.

Check fuel pump by disconnecting fuel line input to carb and direct to a clear bottle. Turn ignition on and check for constant flow of fuel without hesitation. These little carbs need stuff all fuel pressure but do need a constant feed.

Hopefully it's the pump because these Mikunis are a POS.

I dont know the type of carby set up, but its sounds like vacuum advance is not working.

If it was a fuel supply prob id feel it would splutter not lack power.

I agree, although I am not familiar with this model suzuki it sounds like a vacuum hose has come loose or is broken causing a lack of suction for the advance. Had this problem a few times with cars from the 60's and 70's when I was young.
