Brand new oem carb or a Chinese knockoff? Ohming out the spark plug wire and coil would be a quick way to rule out ignition but it sounds like carb to me
Brand new oem carb or a Chinese knockoff? Ohming out the spark plug wire and coil would be a quick way to rule out ignition but it sounds like carb to mePut a brand new carb on
i've heard of people drilling out the cap but i was kinda hesitant on doing so for damaging the pilot underneathThe EPA makes them cap it. I'm yet to see one that can't be removed
didn't buy a ebay chinese special carb. I paid nearly 200 bucks for this damn thing. Plus the original carb that was on it was on its last leg and was giving me more issues than i wanted to try and rebuild it for. plus the original has long since been trashed by about 2 years ago. the one that was in the picture was its replacement and then this new one i got is giving me the same problems as the one in the pictureWhy did you replace the carb in the first place? Was it dirty or giving issues?
If possible clean the old carb and reinstall it. I suspect it will work better than the eBay Chinese special you installed.
Welcome aboard. Lots of information to keep that bike running for years yet.tag. Similar issues.
New to forum, new to Grizzly, gift from a friend. 2001 YFM600 with 602 miles on it, has been sitting for at least three years. Degunked tank, replaced plug, removed mouse nests (seriously), pulled carb and cleaned/reassembled, had engine running last night but wouldn’t idle well, some “missing” and occasional backfiring (carb AND exhaust).
Tried again today, ran a boatload of Seafoam into carb after getting it running again - but ONLY with choke on full - now it’ll run, and idle a bit better. Think a passage or jet might still be clogged, narrowed, but I like these old mikunis; been about 30 years since I worked on one, had yamahas in the 1970s, a Norton commando 850 I put a Mikuni on for a while. Parts are big enough these old eyes can still see ‘em.
I got an “OEM” parts/rebuild kit in the mail today, I’ll pull the carb again, clean, replace, and see what happens next.
Great forum, I’ve been lurking for a couple of days now (just picked up the ATV on Sunday, tore into it yesterday AM, changed oil, etc.), thanks for any answers/suggestions, hints/tips.
Seems like there’s a boatload of aftermarket (ie. cheap chicom knockoff) parts (CDIs, coils, magnetos, voltage regulators, carbs, etc) on ePay and amazon. I’d like to keep this alive for a few years yet, use it on my farm in TN when i finally retire there.
Got a ‘92 HMMWV 6.2L NA diesel I’ll be using around the property too, ATV’s easier to get in and out of the garage and on some trails I might need the HMMWV’s hydraulic winch to pull out of.
Thanks again.
