Hello Coopart1

If it accelerates from any speed without hesitations [lean] or without "burbling/sputtering" then your jetting is very close. You need to check plug color at that point to fine tune jetting if you desire. If it runs fine and plug color is good as I previously described you do not need to rejet it to oem specs, this may cause.problems. If it ain't broke don't fix it.

Glad my previous suggestions helped.


Hope this new info helps.

"burbling/sputtering" = rich

Based upon your new cold start description and idle screw setting your pilot jet is ideal for your conditions.


sorry i have no edit button

not to keep a dead thread alive, just an update....yes i agree with your advise, i might just leave it alone (the jet) got home late (because i went and bought another 3 wheeler!) set the pilot another 1/4 turn rich, went for a ride after a normal startup, a few pulls, very little choking, took off while it was still a little cold but no choke on...ran a little blurpy on the lower end of the throttle till it warmed up then ran pretty good, went for about a twenty min ride...let it cool down then pulled the plug. now mind you up till this point that new plug was mostly sooty and somewhat wet, but i was glad to see it getting lighter at the spark points and looking normal...im pretty happy with the sound too..no backfire on throttle down..pretty smooth throtttle up...etc..its going to be a nice little trike! thanks for your help..!! two or twenty heads are always better than one!!
p.s....will start a new thread about this 84 200es i picked up last night for some barter service and a 100 bucks! wiring issues!!!! yuk!

Hello

Good news and congratulations on the new bike. Just curious did you turn the screw out or in? Either way the pilot jet sounds close but the main sounds big because you say it runs better the warmer it gets. It might spit and cough for about 2 minutes while riding it with the choke off until it warms up but this is normal under some conditions. I personally would lower the needle by raising the clip by 2-3 positions and try it again and also start with a new plug and check it again. I would also try a 1 size smaller main jet once I got around to it and set needle accordingly

Hello Barnett, you know, i see your point..because much of the carb fiddle faddle i did before was when i had multiple issues with it running right..maybe now that valve issue is resolved and other things have been fine tuned like rotor air gap, cleaner connections etc...might be good to revisit the carb setting all together...hey thanks man for helping me see many other options i DO appreciate!! i will take a look see on that jet tomorrow and will have time to try some dif settings, run it out on some multi terrain trails for the real test.

Hello

Thanks for the reply and info. Happy to help, it's strange but frequently I see people with potential jetting problems and some just tell the person to just run it till it dies then worry about it. Being too rich will cause premature ring wear, being too lean can cause other problems.

Might I suggest that you concentrate on how it carburetes from a stop and from cruising speed etc. Also if there is a "hesitation" upon acceleration then please concentrate on whether it is "burbling/sputtering" [too rich] or if it just has a "flat" spot with no burbling or stuttering etc. This is lean. These terms are easily understood by all people that know how to properly jet a carb and it makes it easier for one to offer the proper suggestions for jetting if needed.


Hope this info helps.
