jag afs wont start

It has compression, spark and it's getting fuel. BUT it wont start. I put some mixed fuel down the plug holes, even though I KNEW it was getting gas, and then it fired, but thats it.

I just had it running a few days ago, then it sat out in an ice storm and snow storm. I thought I would take it for a spin but it wont start now.

Any ideas?

Re: jag afs wont start

If it fired when you put fuel in the cylinders then it is not getting adequate fuel supply, plain and simple. It's time for a good carb cleaning.

The carb does need to be cleaned, but the plugs were plenty wet every time I looked at them, I almost thought it was flooded.

I was going to go through the carb regardless when I have some room in the shed.

get new plugs. week spark will not keep up with the fuel and will flood your engine. also make sure you have enough gas! pull the gas lines off at the carbs and pull til it spurts out gas or let it run off premix dropped in the cylinder til gas comes out of the lines. reconnect the fuel and run off premix again to fill carbs.

Weak spark is probably it, now lets just hope it's just spark plugs. Thanks josh.

I know its getting gas, I can see fuel in the line at the carb.

Does it matter if I use br9es or br8es plugs? There is br8es in it now, but I looked it up on NGK website and that says to use br9es.

Re: jag afs wont start

If it says to use br9es, use them. Br8es is a hotter plug and can cause issues. I would highly recomend using the spark plug specifically designed for the sled. I bought new plug wires from oreilly auto parts. Cost 15 for 3 of them (triple) so bout 10 for a twin. Also got some new plugs to go with it. Does your plugs have threaded tops or solid tops?

Re: jag afs wont start

Might have water in the fuel if this happened after ice snow storm

Got the new plugs in, and went to start it, now the recoil takes a good 10 seconds or more to rewind it self..

Do I need a new spring? I have another recoil that's taken apart..do I try putting that spring in to see if it's better?

How do I put a recoil spring in?

I had the same problem, so I did in fact clean it, but now it's the problem is back.

I could use some pointers on cleaning it!

Any certain thing I need to pay attention to while I'm cleaning the recoil?

Re: jag afs wont start

This happened to me before after mine sat in the rain and then got cold . Water got in the recoil and froze. Try putting de-icer on the rope. This may not be the problem but it can't hurt to try it.

I get the recoil off and take it inside to have a good look at it.
