when the motor is warmed up, it fouls the left cylinder. It only does it when its idling.I also have to pull it over about 10 times to get it started, and hold it to the bar. (when motor is already warm). Starts great when its a cold start
1. air mixture setting off?
2. pilot jet plugged?
3. carb just needs to be cleaned ?
Any helpful suggestions would be nice.
Also try checking the spark plug cap resistor. Should be 5k, I think, but it will be on the cap. Just take the spark plug cap off the plug, hold the plug wire and unscrew the cap. Polaris are famous for burning out the resistors in the cap. I've had it happen to some of my Ski-Doo's as well. Now I carry a couple with me. Sounds as though you have a weak spark on that side. You can also switch secondary and primary coil wires to see if the problem changes sides to test the coil.
If it was an ignition problem (cap,wires, etc.) it wouldn't cold start well either. I would bet the the enricher (choke) for the left carb is stuck partially in. I had a sled once that did this exact thing.
Rotary valved engines cannot run enrichers due to the engine pulses generated by the valve. That's why they had primers instead. But good point Mighty Mach to check the check valves in the primer. They have been known to leak fuel thru, into the carb, creating a hard start situation.
I also have a 98 form dlx 583. The left also has fouled on me, I also think it's form ideling.....and slow riding. Mine is also a pig to start when it's warm (thanks for elec. start
)
Does anyone know if they make HD rear springs for this model, as when I ride 2up it's a LITTLE soft.
Here are a few things to check. You could have to much fuel going to the left cly.
Your needle and seat is not sealing or you float level is to high. A plugged pilot jet would give you no fuel. The spark plug cap is a possible problem switch them side to side to see if the problem follows it.
A nother quick question, on both input fule lines on the carbs there are little tiny basket filters that are there, should they still be there, or were they just intended as breaking filters?
I have an early 1970s Bombardier Ski-Doo single cylinder. I need to lower the primary clutch engagement rpm. What spring and weights would make it possible to lower the engagement of the primary clutch. Thanks for any knowledge you can send my way... Chevysteve.
I wasn't interested in a new sled. Was satisfied with my 16 4-Tech 1200 Renegade and my 17 900 ACE Renegade. Dealer talked me into trying his personnal 19 900T Renegade with a chip and reflash. Claims it puts out 190 hp.
Besides being quick,and fast it doesn't lag and handled well. So I...
Hello
My snowmobile is skidoo Formula MX XTC, model year 1995. My skidoo front light work poorly (only 3 volts given) and i was wondering where is the battery located? Or does this skidoo have battery at all? Engine is rotax 467. Anyway there is something wrong with electrics.
I ride a 2001 ski doo touring 500fan, and over the past year have spent a lot of time fixing issues with it (it was sitting unprotected in a backyard for 5 years). I cleaned the carbs, fixed some electrical contact issues, and redid much of the fuel system. It used to bog down when I went past...
First time for the season the brakes lockup and got hot. and continued to do it all day. So replaced the caliper and dot 4 brake fluid cleaned reservoir and tried brakes seemed to work fine. Go out again brake lockup.
Can my rotor be warped causing this brake up?
Thanks in advance
