I have a 2000 DS, When it is cool out my DS is very hard to start. Any ideas?

 

check valve clearance, and maybe a larger pilot jet. new plugs. should be in there some where

 

if you have to hold you'r hand over the mouth of the carb to get it started you need to check valve clearance.

 

Thanks, Dose any one know what the valve clearance is?

 

the manual says .10-.15mm or .004-.006 in. you need to have the piston locked at top dead center. there is a locking bolt on the bottom left of the engine case. do a search and you will find a lot of info on this subject.

 

Did you recently improve flow? (New pipe, air filter, etc.) This will let more air in at the low end as well at the high end. I have noticed a big difference in Pilot size when I change something. I had recently checked my valve clearances and all was good.

Are you running the stock carb or the TM45?

If you have the TM45 a 40 pilot is probably needed.

Also, check your air mixture screw.

If however, you have never checked your valve clearances on your DS. . . it is probably that.

 

All stock still I'am the 2nd owner and I haven't checked valves yeat.

 

hey dune me they put a 47.5 pilot in my 45mm i have noticed i don't need the choke what does this do at other points, it seems to start when it is warm. but was wondering if i'm losing somewhere else? i live in acold area it is at freezing most mornings but when i go to the coast it seems fine.

 

What size is a stock jet?

 

i think the stock pilot is 40 i have a 50 in my stock carb. the main is 165 small round
