Alright I've got actually a 2150 carb installed it yesterday when I first put it one adjusted to float to 16/32 witch I seen would be correct kicked it
Down decently...but still has rough idle the jets in it are .48f and I seen a forum saying run 46 to 47 jets will this help the rough idle any FYI I live in northern Illinois idk if any of the guy around my parts can give me an idea what they are running that would be amazing! Or some sort of other help
There is a little more to setting the carb than just having the correct jets which is important. Timing must be correct. You must set the fuel/air mixture screws based upon vacuum. You need to set idle correctly at around 720 rpm. Also, you cannot have other issues such as vacuum leaks. Search this forum or the web for details on setting this carb. A lot of good info available. Good luck.
Rough idle can be result of many things, Timing is one, Jet size is another, Float setting is a third, Vacuum leaks a third, dirty fuel filter a fourth, Spark plug gap a fifth bad spark plug wires.
So tell us everything you have checked first.
Also what size is the venturii because 46 to 48 is a swag based on your engine and compression and alot of things...best way to check if jets are right is run a quarter mile turn engine off do not let it idle and pull a spark plug is it black too rich to big a jet size, is it all white to lean not big enough a jet size light brown close to perfect.....but that is after you fix all the other potential issues.
Well let's see I've checked the timing was dead nuts. Jet size in it is a 49. Float level is 16/32. I think I found a big issue with a vac leak...new filter with carb. Spark plugs new cap rotor wires and been nuttered
Well...I think I've found my problem. I used a tdp 2089. this adapter on the back side instead of being a straight Line going across to the it's just got ears going all the why around to mount the carb. Well the front of the carb has the ears or tabs that match up but the back side it's square and has a gap that I think is sucking air...kinda hard to explain but I'll try to get a pic. Instead of the 2150 i might have to just go and buy the 2100 instead...anyone have some part numbers or years I could use??
And anyone having this problem here is the fix. If from eBay guy makes them in Colorado. 2150 adapter plate. Seller and producers name on eBay is ehrmannmp(9791
Again sorry for the troubles guys my dumb ass fault for not looking into it a bit more
