Polaris carb question

The marks are just marks from the factory,not identification.This pdf fuel break down can show the two different type carbs used on the two strokes. Smaller VM32 for the 250/300 engines,the VM34 for the 350/400 carbs. https://www.google.com/url?sa=t&rct=...U2gGlaHJWSIlbA Standard jetting for your VM34 was a 200 main jet,30 pilot jet. That may vary depending on altitude/temp. If your carb needs rebuilding/cleaning,these videos can help on these simple carbs.
Carb kits are cheap for these also.https://www.ebay.com/itm/Shindy-Carb...ZaAy9H&vxp=mtr Plenty of these carbs on ebay for around 45 bucks,but you' have to swap the manual choke lever for the cable type,plus swap jetting anyway..

Just get the kit if the carb isn't trashed out to where you can't just clean it and rebuild it. Don't think I've see one that couldn't unless it was physically broken. 200 main was too big imo to begin with especially for down here during the hot summers. 190 main was a good over all year round to use.Most cycle/atv shops have a selection of jets that you can buy individually or you can get them from jetsrus.https://www.jetsrus.com/a_jets_by_ca...2_main_Hex.htm IF the kit doesn't have a 190 jet in it..

Mr.old Polaris tech got the new carb. Vm 34 but the intake side throat is about half an inch bigger than the original. Will that still work ? I'll have to find a carb adapter that will fit on the air box. Is that ok to do and how does that affect performance? Sorry so many questions but rooky.thx

Sens it back and just get the $18 carb rebuild kit like I mentioned.Some of these aftermarket carbs are not the same internal/external dimensions as the oem VM34SS carb that the manual calls for.https://www.ebay.com/itm/92-93-Polar...!US!-1&vxp=mtr
