Hi
I have a bought a used LT1500 mower with Briggs and Stratton engine 31C707 3346 G6 engine Code 110510ZD It has a Nikki Carburetor
It starts right up but surges for a minute or so before it warms up. Then it seems to run fine. Maybe a surge when the PTO is first engaged but I have not used it more than a test.
I did the basics to start fresh with the machine, New : spark plug, fuel filter, oil change, air filter. I also changed the gas. I also tried this with the gas cap and air filter off and it did not change the surging.
It had always been garaged and I am assuming in winter was stored with gas in. So I could see how the carb could have blockage and need a break down and clean. I have not done this but seen quite a few videos are posted about this carburetor and it looks easy enough.
1. if it is only running this way at start up , is it the carb or could it just be an adjustment?
2. If just an adjustment, how should I proceed to give a tune up ? the carb?
I have read some say they either did a clean or even replaced the carb and it still surged after. I never saw them post if they found the cause.
I also see allot of kits on amazon and ebay cheap but mixed reviews. It concerns me I do a rebuild and it does not fix if that is not the issues
So i am asking for help as this could just be an adjustment for cold start and I donot need a clean. I don't understand enough about how they work to know what would only cause the surge at cold start.
And when I say cold.... I mean it is NOT cold. It was High 60s and if I turn off for 10 minutes after it smoothed out. It starts to surges again but not as hard and smooths out quicker When it is cold it surges harder at first and as things warm up it surges quieter and quieter and less frequent until it is running smooth.
3. Is there a good aftermarket kit? I don't want to over spend on a $55 briggs kit if many say it does not fix their surging and does concern me that some replaced the carb and it still did not fix.
4. it seemed the owner knew of this and just played with the choke until it cleared out. when I put the joke up the surge stops for a few seconds and then there is too much fuel so it starts to act up and he dropped it back to fast, the surge was start and he would move the choke back up and repeat . I guess he did this so he did not have to listen to the surge.
But this info might give an expert here an idea if it is more of an adjustment than something in the carb.
Thanks in advance for any advice.
So what do I do
