enticer 250 carb

so i just got a 1979 yamaha enticer 250 for free from a family member. it had been sitting in and open garage since 2000. was told it had bad crank seals and that the carb wasnt working right will. i stated pulling it apart today and cleaned gas tank out and put fresh gas in. so if i spray gas into the carb it will run until it burns off that gas. tomorrow im getting new fuel lines for it and new fuel filter.

here are some numbers i pulled off the carb.

QCO2 & 8G5O1 anyone know what these are for?

ive heard there is a good carb to run and a bad one. can someone tell me what carb exactly i have

Fuel lines and filter are the Least of what you need! With bad seals you will need to pull the motor out and Completely apart! Piston, gasket set and seals! A carb kit complete with the fuel pump diaphram!

Looks like a Keinin pumper.
Although, some of those did use a Carter carb.

looks like the standard keihin carb consistent with yamahas.

your 8G501 is the yamaha part number, the QC02 would be keihins' number.

wish there was. finding parts that fit is one of the larger hurdles, getting the associated parts out with out damage is typically next on the list.

i always wanted to find a replacement carb with corresponding flanges and do away with the tempermental pumper carb, add a remote fuel pump and be done with that hard to tune carb.

long time since i had one of those. when they run, they run good.

that would be a good start, but i think the bravos ran like a 32mm carb and the et250's had like a 38? never could figure that one out.

it will cost you a bit more if the parts are still available, but the oem parts will fit. problem i have run into with the kits from the aftermarkets is about half or better of the kit parts dont seem to fit.

there are a few out there that have specific kits for the keihin carbs, seems like winderosa had a good match.

assuming you can get all the hard parts out like jets, choke plunger, etc, its the diaphragms you need to refresh the carb. you need to take your time and not animal the parts you need to reuse and cant replace.

orientation is key as you have many options as to which way they could go. pictures or markings during the removal process will simplify the rebuild.

tear it down, dip it in some Gunk or any chemical dip (watch out for anything plastic or gaskets) Gunk eats them. After cleaning replace all the gaskets.. Make sure to blow out the jets with air after dunking.
if you want to replace the carb change it to a mikuni slidebore!(35mm?)
you will get better throttle response and its a all the way around better carb.

but i have rebuilt about 5 of those carbs.. not that hard.
