My 670 does not like to start very well when she's warm. Usually, if I don't give a little bit of thorttle, she won't go. If I just pull the rope, sometimes it will start but barely idle. I have heard that some of the "older" sleds (90's) are tough to start that way.
Is there a fix for it or do I just have to give it a bit of gas every time?
I have a 97' mxz 670 that does the same thing. It starts better when it is cold than when it is hot. All I know to do is sit on your seat, give about 1/4 throttle with one hand and pull with the other hand. I would also like to read sugestions on how to fix this.
Rocketman: One of the main causes could be wear on the crankcase at the R.V. openings. As these motors get older is becomes more of a problem. As you pull the engine over it has very little vacuum signal to pull fuel in to start, thats why all of the R.V. engines have primers and not enrichment valves. Dino
For whatever reason, my '00 700 MXZ with DPM was the same way. If it was warm, you'd have to give it a little throttle to start it. The '01 800 seems to be OK in this regard.
My 00' MXZ 700 W/DPM has the same problem also. It starts cold on the 2nd or 3rd pull everytime, but when it's warm it sometimes takes about 4. I find that holding the throttle open a hair helps though.
I have a 2000 MXZ 700 with the same problem. I crack my throttle 1/2 open and pull. It starts on the first pull everytime. Cold starts, second to third time. Most of the series 3 motors are like this.
Rocketman : Yes behind the R.V., As the motor sucks it a fresh charge, it also tries to suck in the R.V. as well and it wears just above the mag port and below the pto port. Skidoo changed the design back a few years ago to prevent this and from what I see it helped. Dino
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
