Hi, Background: I recently acquired a 1993 dr350s and I cannot fix a rich condition; I am about to purchase a TM33 pumper carb off of eBay but I hate when I am not able to figure something out. Hopefully someone here is able to give some insight! Tried: The bike is 100% stock. I have replaced the vacuum petcock with a standard one, and replaced every jet and rubber piece float and needle with OEM Suzuki pieces, triple checked float height, the idle, main jet, and choke valve and seat surfaces appear to all be in perfect condition, etc. Symptoms: With the bike fully warm and choke off, the bike idles highest with the idle mixture screw all the way lean and dies if any choke is applied. It also smells rich, does not hot start, spits black soot, and pops on deceleration, low power, etc. The only unusual thing is where the idle mixture screw pulls fuel from there are three little pinholes drilled straight through into the throat of the carb. They do not look OEM, and I tried to epoxy them shut but I think I rushed it and the gas ate my JB weld... are these factory or did someone try to correct an old vacuum leak with this? Thank you!
So let me start by introducing myself, I'm shifty00 (I would tell you my real name but I don't trust the interwebs haha) am new to this forum. I am a welder/fabricator and I have decided to build something fun as a project. I got a Yamaha Warrior 350 for building my buddy a rack for his RZR. This thing was beat but it was free so whatever. Anyhow I went to drain the oil and found about 30lbs of magical pixy dust on the oil filter. I did manage to get it running but it was spewing smoke and didn't enjoy starting. long story short I decided it would be more fun to make a hybrid rather than dumping money into an already "Meh" engine. That leads me too my purchase of a 1993 XR600R engine on Craigslist. I looked it over, some things are missing but all and all it looks ok, it came with a carb and at the time I was skeptical about the carb because it just looked too damn busy for an xr motor. And now after knowing what that OEM carb looks like I know this is not at all an XR carb. It has features I wouldn't mind but I have no clue what it is or if it would even work on the motor. It is a CV and a pumper and has remote choke (dose not stay engaged, feels like a spring pulls it back closed?) Anyhow can someone please tell me what the heck it is... I can't find a single damn marking on it, so I assume its some china crap but I really don't know. here is a link the previous engine owner gave me after I txted him asking what the hell carb he gave me.... http://www.ebay.com/itm/262774188434 Also can anyone tell me if I will have oil starvation issues if it tilt the motor at a sharper angle than it would sit in the dirtbike frame? I figured dry sump would be very forgiving in that area but I worry about oil pooling to the front of the head and stuff like that. I will have about 1,000,000 questions but lets start here haha. Here is a pic of the infant stage of the build. (engine is just resting in there no mounts made yet). Thanks for any help with my Yamda/Honaha YFM600R...
