Hi all,
it was so sad when I was cleaning the carb on my 1988 trail boss 250 and broke the carb body when I was taking the float arm pin and one of the legs on which the float arm hangs just cracked and broke off!

I searched ebay there are no exact carbs that I have. There are a lot of carbs for Trailblazer that are simular.

Could someone tell me what would be the closest match to replace my carb?

Thanks!

 

Seen this happen a lot. Doesn't help you now,but any time you use a pin punch you have to place your thumb over the float posts or you'll break one if the pin is stuck. You can use any Trail Blazer or Trail Boss carb as they all use vm30ss Mikuni carbs. You might try as some have done,once you get it back together use JB quick set epoxy under and around the broken post when the pin is replaced and let it sit over night. Worth a try before you spring for another carb.

 

Thank you OLD POLARIS TECH for the tips. I did actually think to use JB Weld to fix it but wasn't sure if it would withsdand in gasoline.

One other option I was thinking is to take it to a good aluminum welder and have it welded. What do you think?

 

I've used jb weld on carbs that people have brought in like this and don't think I had one come back. Main thing is don't gob it on,just enough around and under the post to hold it without interfering with the float arm or getting it close to the bowl gasket.

 

Thanks Old Polaris Tech!
Today I made a stop at my buddy's shop, he is very good welder, and asked if he thinks this can be welded, he said let's try now.
He tried and said looks liek it can be welded, so he did weld it right than and it worked out good!
Here is how it looks now, I'm so happy!

 

Looks like he is a good welder. Takes a good one to weld aluminum/magnesium without over heating and making a mess. If the pin goes straight into the other post that's all that matters and if the bowl fits flush without interference.Looks better than some of my Jb weld jobs.. Hopefully this is a lesson to others on how to safely remove float arm pins. If you use a pin punch to remove the pin or even if you have enough room to grab the head of the pin with small pliers and pull it out,always put firm pressure on both posts with your thumb.
