1998 Yamaha Timberwolf

[KINGSIZE]

Howdy,

 

I was given a 2008 Yamaha Timberwolf by my in laws a few weeks back. Of course my FIL said it hasn’t run in 8 years but all it needs is gas and oil!

 

That hasn’t been the case...so far I’ve replaced the spark plug, changed air filter, replaced battery, replaced fuel and oil filters, fresh oil and gas. I tried starting her up and no luck, it turns over but won’t get going.

 

Now I’ve moved on to cleaning the carburetor which I’ve heard is a common problem area. I can’t figure out how to remove the bowl at the bottom, any suggestions? I removed the four screws that I thought were holding it in place but the bowl won’t budge

 

Thanks and looking forward to getting her running!

Should come off, may have to pry it off with a flathead screwdriver, gasket may just be corroded on. Maybe light tap with a rubber mallet.  If it’s been sitting for a while, check the float, sometimes they get stuck from sitting for years.

Have you checked to see if it's making a spark?

usually a good smack to the fuel bowl with a screwdriver handle will bust it loose.

if you need cheap parts they make a chinese copy, the jianshe 250. i use one of their CDI`s. Bought it for $30 instead of an original for $400 and it has been good for the last 4 years. i have also replaced the carby with a $35 chinese one that works good after i reused the original carbs jets and needle

Thanks for all of the advice. It is making a spark when holding the plug against the engine side and pressing the starter button.

I cleaned the carb bowl which still has minor corrosion and it’s still not starting. Does it have to be squeaky clean?

The needle, spring, and float all seem to be functioning properly within the carb l.

I’m thinking about taking it to a small engine mechanic because they may be able to diagnose the problem immediately.

Hey @KINGSIZE welcome to Quadcrazy. 
wen taking the carb apart to clean you have to break it all the way down to make sure all the passages are clear. Here is a topic on properly cleaning a carb, give it a shot and take your time. After this is done she will fore right up and it will be a matter a making some minor final adjustments to dial it in.

Thanks for the suggestion Frank, that is a very thorough write up. Now I just need to find some time to get started on a detailed clean
